MMarshall:

System statistics provide information about overall performance and
status of the Online system.
Some identically named statistics might also be available on the user, file, subsystem, or task level.
Generally, an identically named statistic for a different context will have a similar meaning to the system context.

In RKWeb, you can display all the system statistics and view their descriptions by selecting <code>Performance > Custom</code> from the <code>Monitor</code> tab, then clicking the System radio button.

Using system statistics

2025-08-21T23:19:40Z

MMarshall:

==Overview==

The tables on this page are provided for your use in identifying and tracking statistics that are reported by <var class="product">Model 204</var> in various situations. The offsets, given in decimal and hexadecimal, are to help you locate particular statistics within statistical output. The length is in bytes.

The statistics are collected in the [[Tracking_system_activity_(CCAJRNL, CCAAUDIT, CCAJLOG)#Introducing CCAJRNL|CCAJRNL]] data set, or if allocated, in [[Tracking system activity (CCAJRNL, CCAAUDIT, CCAJLOG)#Introducing CCAAUDIT and CCAJLOG|CCAJLOG]]. The offsets in the tables below locate each statistic in the corresponding record. To accommodate sites that need to run <var class="product">Model 204</var> around the clock for many days at a time, space for most <var class="product">Model 204</var> statistics is a double word.

==Description of statistics==

The "Statistics with descriptions" table lists the statistics that are collected and that you can evaluate. It also describes the purpose of each statistic followed by the circumstances when you can collect the information and an offset in the journal record. 

To collect several statistics you must preset a parameter to a nonzero value. Statistics that require a parameter are also noted in the "Statistics with descriptions" table. The table in [[Tracking system activity (CCAJRNL, CCAAUDIT, CCAJLOG)#Setting parameters to collect certain statistics|Setting parameters to collect certain statistics]] lists those statistics with the required parameter. 

Tables, identified by type, later in this topic, describe the layouts of the various journal records.

Since Imagine guarantees identical results for identical finds in the same transaction (if no candidate files were updated) the result of the previous find can be used in the case of a duplicate, eliminating an interaction with the broker and all the overhead that entails. The H in IMGTFDH stands for Hits. It can be useful to compare IMGTFDH with IMGTFND (finds sent to the broker) to determine the percentage of finds that were essentially optimized away as duplicates</td>

===Recovery flags===

Flags used by recovery can have the value of X'00' or a sum of any of the following: 
<table>
<tr class="head">
<th>Value</th>
<th>Block contains these records...</th>
</tr>

<tr>
<td>X'80'</td>

</table>

===Sequence numbers===

The sequence number represents the number of each journal record, starting at 0 and increasing by 1. A merged journal (output of the MERGEJ utility) sequence number consists of a 2-byte hexadecimal number at offset 12(0C), which indicates the input file this journal record came from, and a 2-byte hexadecimal field at offset 14(0E), which indicates the sequence within the INPUT journal.

===Trailer entries (Type 0)===

Trailer entries have the format shown in the following table: 
<table>
<caption>Trailer entry formats</caption>

</table>

==Recovery entries (Types 1-6)==

Entry types X'01' through X'06' contain information used for recovery. They follow the same general format as all other journal entries. There is no type X'07' journal entry. 

The format of the recovery entries is meaningful only in the context of the <var class="product">Model 204</var> ROLL FORWARD algorithm. However, entry types might be of interest in some statistics gathering applications, as follows: 
<table>
<tr class="head">
<th>Type </th>
<th>Contains recovery information from...</th>
</tr>

<tr>
<td>1 </td>
<td>Discontinuity</td>
</tr>

<tr>
<td>2 </td>
<td> Begin update unit.

More than one type 2 entry can be written for each update unit. The update unit number appears as a 4-byte binary number at offset 16(10).
</td>
</tr>

<tr>
<td>3 </td>
<td> End update unit.

The update unit number appears in the same format and location as the type 2 entry.
</td>
</tr>

<tr>
<td>4</td>
<td>File state information: opened, closed, dumped, file parameter list (FPL) page preimage logged or open at the time of a checkpoint</td>
</tr>

<tr>
<td>5 </td>
<td>Checkpoint</td>
</tr>

<tr>
<td>6 </td>
<td>File update </td>
</tr>
</table>

==System statistics entries (Type 8)==

Cumulative statistics, listed by offset in the [[#System performance statistics|Layout of system subtype X'02' entries]] table, are kept for the entire system. Final, partial, and performance system statistics are written to the journal during <var class="product">Model 204</var> termination in a line that begins with:
ST $$$ SYSTEM='version#'


For additional information about:
<ul>
<li>Using system statistics for performance monitoring, see [[Performance monitoring and tuning]]. </li>

<li>Disk buffer monitor statistics and parameters, see [[Performance monitoring and tuning#Disk buffer monitor statistics and parameters|Disk buffer monitor statistics and parameters]]. </li>
</ul>

===Final statistics===

The system final statistics line, similar to the following, is produced as part of system termination: 
ST $$$ SYSTEM='5A 'AUDIT=43 OUT=38 IN=14 WAIT=19 ...


===Partial statistics===

Statistics in a system partial statistics line, similar to the following, accumulate from the beginning of the run, if the User 0 <var>[[ACCTIM parameter|ACCTIM]]</var> parameter is nonzero: 
ST $$$ SYSTEM='6.1.0'PARTIAL=3 AUDIT=19 OUT=10 IN=5 WAIT=3 ...


===Performance statistics===

System performance statistic lines, similar to the following, are written if the User 0 <var>[[RPTCNT parameter|RPTCNT]]</var> and <var>[[SMPLTIM parameter|SMPLTIM]]</var> parameters are nonzero: 
ST $$$ SYSTEM='6.1.0' PERFORMANCE=n


The numbers determined at the performance sample points are averaged for the entire run. 

===Entry formats===

System statistics entries have the format shown in the following table:

==User statistics entries (Type 9)==

User lines report on an individual user's activity. These statistics include:
<ul>
<li>Final (logout) and partial statistics</li>

<li>Since-last and ordered index statistics</li>

<li>Performance statistics</li>
</ul>

Each user line starts with the following statistics:
ST $$$ USERID='userid' ACCOUNT='account'


The subtype, in this case PERFORMANCE, follows USERID and ACCOUNT statistics:
ST $$$ USERID='userid' ACCOUNT='account'
PERFORMANCE=n


The format of user statistics entries is shown in the following table:

==User final and partial statistics==

===Final (logout) statistics===

Final (logout) statistics, listed in the [[#Partial statistics|Layout of user subtype X'00' and X'02' entries]] table, summarize a user's activities since the last login. A LOGOUT statistics line, such as the following, is written after each logout if the parameter following ACCOUNT is not PARTIAL, LAST, or PERFORMANCE: 
yydddhhmmssnnnsssuuuuu ST $$$ ACCOUNT='NO ACCOUNT' SQRD=5 ...

<ul>
<li><var class="term">yyddd</var> is the year and Julian day.</li>

<li><var class="term">hhmmss</var> is the time of day in hours, minutes, and seconds.</li>

<li><var class="term">nnn</var> is a counter to distinguish lines produced in the same second.</li>

<li><var class="term">sss</var> is the number of the server currently handling the user. Leading zeros are suppressed.
</li>

<li><var class="term">uuuuu</var> is a 5-digit user number associated with the audit trail line. Leading zeros are suppressed.</li>
</ul>

In some cases, the account name appears as "NO USERID NO ACCOUNT". Statistics in this category are not chargeable to any one user and should be considered system overhead.

Final lines are recognized by the absence of an indicator for another type of line.

===Partial statistics===

Optional partial statistics, listed in the "Layout of user subtype X'00' and X'02' entries" table below, can be provided for a run up to a few minutes before a system failure that prevents normal termination and production of final user and system statistics. 

User partial statistics lines, such as the following, are made available for active users: 
ST $$$ ACCOUNT='NO ACCOUNT' PARTIAL=21 ...


Statistics accumulate either:
<ul>
<li>As long as the user is logged in</li>
</ul>

or
<ul>
<li>From the first terminal input to disconnection when a login is not required </li>
</ul>

Partial statistics are requested by setting the time interval, in minutes, between successive partial lines on User 0's parameter line with the <var>ACCTIM</var> parameter. <var>ACCTIM</var> must be nonzero. 

The contents of the statistics portion of the entry, starting at offset <code>40(28)</code>, depends upon the subtype of the entry. 

Partial statistics lines are indicated on the journal by the parameter <code>PARTIAL=n</code>, where <var class="term">n</var> is a counter from the beginning of the run. <code>PARTIAL=n</code> immediately follows the type parameter.

For subtypes X'00' (logout statistics), and X'02' (partial statistics), the layout of the remainder of the entry is shown in the following table. Each statistic in the table is: Length, 4; Data type, Binary. For the meaning of each statistic, see the [[#Description of statistics|Statistics with descriptions]] table.

==User since-last statistics==

===Since-last statistics===

Statistics are kept for each SOUL request, host language interface call, and a number of <var class="product">Model 204</var> system commands. When each request or command completes, a since-last statistics line is written. The line includes the <var>ACCOUNT</var> parameter at the beginning, followed by the <var>IODEV</var> parameter and the <var>LAST</var> parameter.

Several <var>MONITOR</var> commands produce displays containing the user's last or current activity in the <code>FUNC</code> column. When this activity completes, statistics are also written to CCAAUDIT and the activity is described in ST lines as <code>LAST='activity'</code>.

====Syntax====
ST $$$ USERID='userid' ACCOUNT='accountname' IODEV='devicetype' LAST='acty'

<var class="term">acty</var> can be one of the following:

===Since-last highwater marks===

The since-last statistics include highwater marks of various work tables used by SOUL requests. Values are reported in terms of the units in which each table is allocated. For example, QTBL is allocated in units of 16 bytes.

===Since-last in relation to final and partial statistics===

Many since-last statistics, such as CNCT, CPU, and DKRD, are also reported on user final and partial statistics lines. (See the [[#Description of statistics|Statistics with descriptions]] table.) The statistics on these lines are roughly equal to the sum of all of the preceding since-last statistics for the user.
Because since-last statistics are not maintained for every <var class="product">Model 204</var> command, final statistics are generally larger.

For subtype X'01' (since-last statistics), the layout of the remainder of the entry begins as shown in the following table.
For the meaning of each statistic in this table and in the [[#Conflict statistics|Layout of user subtype X'01' entries (CFRJRNL=0)]] table, see the [[#Description of statistics|Statistics with descriptions]] table.
The layout of the end of the entry depends on whether you chose to collect conflict statistics:
<ul>
<li>If you do not collect conflict statistics, the end of the entry is described in the [[#Conflict statistics|Layout of user subtype X'01' entries (CFRJRNL=0)]] table.</li>

<li>If you do collect conflict statistics, the end of the entry is described in the [[#Conflict statistics|Layout of user subtype X'81' entries (CFRJRNL=1)]] table. When you collect conflict statistics, the subtype changes to X'81'. </li>

===Conflict statistics===

Whether you are collecting conflict statistics determines the layout at the end of the entry. Two of the conflict statistics keep track of critical file-resource conflicts, and two keep track of record-locking conflicts. Whether these statistics are collected and journaled depends on settings of the parameters <var>[[CFRLOOK parameter|CFRLOOK]]</var> and <var>[[CFRJRNL parameter|CFRJRNL]]</var>.


These statistics are not displayed with the output of the <code>MONITOR SL</code> command. Instead, you can view them (with all the other since-last statistics) by issuing the <var>MONITOR</var> command with the keyword <var>CONFLICT</var>.

The remainder of the entry depends on the setting of <var>CFRJRNL</var>.

The following table shows the layout when <var>CFRJRNL</var> is set to 0: 
<table>
<caption>Layout of user subtype X'01' entries (CFRJRNL=0)</caption>
<tr class="head">
<th>Offset dec(hex)</th>

The following table shows the layout when <var>CFRJRNL</var> is set to 1. It reflects the change in offset and that the user subtypes are now X'81' entries.

Note:
The conflict statistics, BLKCFRE, BLKRLK, WTCFR, and WTRLK, are inexact. Although a user might at times conflict with multiple other users, only the first conflict encountered is counted.

==User performance statistics==

Optional performance statistics lines provide information about the operation of the <var class="product">Model 204</var> scheduler during a short period of time. Information about the length of the scheduler queues, the number of active users and servers, and the queue distribution for each user, is obtained by sampling. 

A performance line starts with:
ST $$$ USERID='userid' ACCOUNT='accountname'
PERFORMANCE=n


===Parameters to activate performance statistics===

To request performance statistics, specify the number of samples to take between performance statistics lines (<var>RPTCNT</var> parameter) and the time interval between samples (<var>SMPLTIM</var> parameter) on User 0's parameter line. When you request scheduler and server performance data (<var>SMPLTIM</var> parameter), an asynchronous operating system task, called the performance subtask, is created. Both <var>RPTCNT</var> and <var>SMPLTIM</var> must be nonzero.

===Sampling===

The performance subtask spends most of its time in a wait state. Every <var>SMPLTIM</var> milliseconds, it records the current state of the system. Data from the most recent sample is available at an Online terminal through the <var>MONITOR</var> command, described in [[Controlling system operations (CCAIN)#ONLINE monitoring|ONLINE monitoring]]. 

The number of samples taken during a run (<var>RPTCNT</var>), times the number of users in the run (<var>NUSERS</var>), must be less than 4.2 million. In large systems that run for a very long period of time, the time interval between samples cannot be extremely short. If the limit is exceeded, an OC1 interrupt occurs when the SMPLS statistic value is calculated during the printing of the system statistics, either a performance or final line.

====Layout of performance statistics====

For subtype X'04' (performance statistics), the layout of the remainder of the entry is shown in the following table.
Each statistic in the table is: Length, 4; Data type, Binary. For the description of each statistic, see the [[#Description of statistics|Statistics with descriptions]] table.

==File statistics entries (Type 10)==

File statistics, summarized in the [[#File statistics journal records layout|File statistics entry formats]] table, are kept for every file opened during a run, including CCAGRP, CCASYS, and CCATEMP. The activity of a file for all users is summarized from the time the file is first opened until the last user issues a <var>CLOSE</var> command. The statistics appear after the last <var>CLOSE</var> command in lines that follow the date and time information (yyyydddhhmmssnnnsssuuuuu) with: 
ST $$$ FILE='filename'


System termination writes file statistics for each file still open at the end of the run.

===Final statistics===

A final statistics line similar to the following is produced when the last user of a file closes the file: 
ST $$$ FILE='PAYABLES'DKRD=25 DKRD=25 DKWR=15 REQ=3 RECADD=6 ...


===Partial statistics===

File partial statistics lines similar to the following are furnished for each open file: 
ST $$$ FILE='PAYABLES'PARTIAL=3 ...


===File statistics journal records layout===

File statistics entries have the format shown in the following table.
For a description of each statistic, see the [[#Description of statistics|Statistics with descriptions]] table.

==Text entries (Type 11, Type 13)==

Type 11 (X'0B') and Type 13 (X'0D') entries record most of the actual text of the audit trail.

===Noncontinued text entries, Type 11 (X'0B')===

Each Type 11 journal entry corresponds to one logical entry in the audit trail, even though it might generate more than one line of physical output in the audit trail. 

The format of a Type 11 entry is shown in the following table:

==System Management Facilities==

You can write certain statistics to the System Management Facilities (SMF) data set by: 
<ul>
<li>Setting the <var>[[SMFSLRN parameter|SMFSLRN]]</var> and <var>[[SMFLORN parameter|SMFLORN]]</var> parameters on the User 0 command line to activate the SMF feature. (z/OS and z/VM)</li>

<li>Modifying the program that processes the SMF data set to handle the records written by <var class="product">Model 204</var>. (z/VM only)</li>
</ul>

See the [[#z/VM requirements|z/VM requirements]] and the the [[#z/OS requirements|z/OS requirements]] sections for details.

Since-last statistics or logout statistics can be written concurrently with statistics that are written to the journal. Logout statistics are more complete than since-last statistics. Many more since-last records than logout records are usually written. 

If the operating system crashes before a user logs out, the SMF data set has a since-last record for every request run, but no logout record. 

File and system statistics cannot be written to the SMF data set.

During system initialization, <var class="product">Model 204</var> issues a message reporting the SMF system ID, the run's job name, the step name, and the JES ID. For operating systems other than z/OS, the JES ID is blank.

===z/VM requirements===

In the CMS interface to <var class="product">Model 204</var>, you can incorporate a user-written accounting exit that invokes the ACCTEXIT routine to process each statistics record as it is written. The following considerations apply:
<ul>
<li>Take care to preserve the CMS environment in which <var class="product">Model 204</var> is running. Do not change the contents of general registers 13 and 14.</li>

<li>You must specify the <var>SMFLORN</var> and/or <var>SMFSLRN</var> parameters on User 0's parameter line to activate accounting record production.</li>

<li>TEXT file for the ACCTEXIT module must be available on an accessed disk when generating M204CMS using M204GEN. For complete installation procedures, see the <var class="book">Rocket Model 204 z/VM Installation Guide</var>.</li>
</ul>

===z/OS requirements===

To write since-last SMF records in a z/OS environment, activate the SMF feature. 

To activate SMF, set the following parameters on User 0's parameter line: 
<ul>
<li>SMFSLRN — SMF record number for since-last records</li>

<li>SMFLORN — SMF record number for logout records </li>
</ul>

The following considerations apply:
<ul>
<li>Since-last SMF records are written only if the SMFSLRN parameter is set to a non-zero value at the beginning of the run.</li>

<li>Logout SMF records are written only if the SMFLORN parameter is set to a non-zero value at the beginning of the run.</li>

<li>If both parameters are set, each type of record is written.</li>
</ul>

SMF record numbers, which identify the record type to the programs that process the SMF data set, are written as part of the header of the SMF records. The record numbers must be between 128 and 255.

See the "System Management Facility record layout and statistics" section, which follows.

MMarshall:

System statistics provide information about overall performance and
status of the Online system.
Some identically named statistics might also be available on the user, file, subsystem, or task level.
Generally, an identically named statistic for a different context will have a similar meaning to the system context.

In RKWeb, you can display all the system statistics and view their descriptions by selecting <code>Performance > Custom</code> from the <code>Monitor</code> tab, then clicking the System radio button.

==Overview==

The tables on this page are provided for your use in identifying and tracking statistics that are reported by <var class="product">Model 204</var> in various situations. The offsets, given in decimal and hexadecimal, are to help you locate particular statistics within statistical output. The length is in bytes.

The statistics are collected in the [[Tracking_system_activity_(CCAJRNL, CCAAUDIT, CCAJLOG)#Introducing CCAJRNL|CCAJRNL]] data set, or if allocated, in [[Tracking system activity (CCAJRNL, CCAAUDIT, CCAJLOG)#Introducing CCAAUDIT and CCAJLOG|CCAJLOG]]. The offsets in the tables below locate each statistic in the corresponding record. To accommodate sites that need to run <var class="product">Model 204</var> around the clock for many days at a time, space for most <var class="product">Model 204</var> statistics is a double word.

==Description of statistics==

The "Statistics with descriptions" table lists the statistics that are collected and that you can evaluate. It also describes the purpose of each statistic followed by the circumstances when you can collect the information and an offset in the journal record. 

To collect several statistics you must preset a parameter to a nonzero value. Statistics that require a parameter are also noted in the "Statistics with descriptions" table. The table in [[Tracking system activity (CCAJRNL, CCAAUDIT, CCAJLOG)#Setting parameters to collect certain statistics|Setting parameters to collect certain statistics]] lists those statistics with the required parameter. 

Tables, identified by type, later in this topic, describe the layouts of the various journal records.

<ul>
<li>If the flag byte at offset 3 of type 00 has the X'02' bit on, then it is a header record from <var class="product">Model 204</var> version 7.4.0 or later with its length at offset X'1A'.</li>

<li>If that flag byte has the X'01' bit on, then the header is from version 7.1.0 and is 26 bytes in length. </li>

<li>If neither of those bits is on, then the header is a from a pre-7.1.0 version and is 16 bytes in length.</li>
</ul>

===Recovery flags===

Flags used by recovery can have the value of X'00' or a sum of any of the following: 
<table>
<tr class="head">
<th>Value</th>
<th>Block contains these records...</th>
</tr>

<tr>
<td>X'80'</td>
<td>Type 1</td>
</tr>

<tr>
<td>X'40'</td>
<td>Type 2</td>

<td>Type 4</td>
</tr>

<tr>
<td>X'08'</td>
<td>Type 5</td>
</tr>

<tr>
<td>X'04'</td>
<td>Type 6</td>
</tr>
</table>

===Sequence numbers===

The sequence number represents the number of each journal record, starting at 0 and increasing by 1. A merged journal (output of the MERGEJ utility) sequence number consists of a 2-byte hexadecimal number at offset 12(0C), which indicates the input file this journal record came from, and a 2-byte hexadecimal field at offset 14(0E), which indicates the sequence within the INPUT journal.

===Trailer entries (Type 0)===

Trailer entries have the format shown in the following table: 
<table>
<caption>Trailer entry formats</caption>
<tr class="head">
<th>Offset dec(hex)</th>
<th>Length</th>
<th>Data type</th>
<th>Description</th>
</tr>

<tr>
<td> 0(0)</td>

</tr>

<tr>
<td> 8(8)</td>
<td align="right"> 4</td>
<td>Unsigned packed data </td>
<td>Time = HHMMSSTH</td>
</tr>
</table>

==Recovery entries (Types 1-6)==

Entry types X'01' through X'06' contain information used for recovery. They follow the same general format as all other journal entries. There is no type X'07' journal entry. 

The format of the recovery entries is meaningful only in the context of the <var class="product">Model 204</var> ROLL FORWARD algorithm. However, entry types might be of interest in some statistics gathering applications, as follows: 
<table>
<tr class="head">
<th>Type </th>
<th>Contains recovery information from...</th>
</tr>

<tr>
<td>1 </td>
<td>Discontinuity</td>
</tr>

<tr>
<td>2 </td>
<td> Begin update unit.

More than one type 2 entry can be written for each update unit. The update unit number appears as a 4-byte binary number at offset 16(10).
</td>
</tr>

<tr>
<td>3 </td>
<td> End update unit.

The update unit number appears in the same format and location as the type 2 entry.
</td>
</tr>

<tr>
<td>4</td>
<td>File state information: opened, closed, dumped, file parameter list (FPL) page preimage logged or open at the time of a checkpoint</td>
</tr>

<tr>
<td>5 </td>
<td>Checkpoint</td>
</tr>

<tr>
<td>6 </td>
<td>File update </td>
</tr>
</table>

==System statistics entries (Type 8)==

Cumulative statistics, listed by offset in the [[#System performance statistics|Layout of system subtype X'02' entries]] table, are kept for the entire system. Final, partial, and performance system statistics are written to the journal during <var class="product">Model 204</var> termination in a line that begins with:
ST $$$ SYSTEM='version#'


For additional information about:
<ul>
<li>Using system statistics for performance monitoring, see [[Performance monitoring and tuning]]. </li>

<li>Disk buffer monitor statistics and parameters, see [[Performance monitoring and tuning#Disk buffer monitor statistics and parameters|Disk buffer monitor statistics and parameters]]. </li>
</ul>

===Final statistics===

The system final statistics line, similar to the following, is produced as part of system termination: 
ST $$$ SYSTEM='5A 'AUDIT=43 OUT=38 IN=14 WAIT=19 ...


===Partial statistics===

Statistics in a system partial statistics line, similar to the following, accumulate from the beginning of the run, if the User 0 <var>[[ACCTIM parameter|ACCTIM]]</var> parameter is nonzero: 
ST $$$ SYSTEM='6.1.0'PARTIAL=3 AUDIT=19 OUT=10 IN=5 WAIT=3 ...


===Performance statistics===

System performance statistic lines, similar to the following, are written if the User 0 <var>[[RPTCNT parameter|RPTCNT]]</var> and <var>[[SMPLTIM parameter|SMPLTIM]]</var> parameters are nonzero: 
ST $$$ SYSTEM='6.1.0' PERFORMANCE=n


The numbers determined at the performance sample points are averaged for the entire run. 

===Entry formats===

System statistics entries have the format shown in the following table: 
<table>
<caption>System statistics entry formats</caption>
<tr class="head">
<th>Offset dec(hex)</th>
<th>Length</th>
<th>Data type</th>

<li>[[#System performance statistics|System performance statistics]]</li>

<li>[[#Additional disk buffer monitor statistics|Additional disk buffer monitor statistics]]</li>

<li>[[#User since-last statistics|User since-last statistics]]</li>
</ul>
</td> </tr>
</table>

==System final and partial statistics==

For subtypes X'00' (final statistics) and X'01' (partial statistics), the layout of the remainder of the entry is shown in the following table.
For a description of each statistic, see the [[#Description of statistics|Statistics with descriptions]] table.
The following statistics are data type Binary. However, the length varies — either 4 or 8, to accommodate 64-bit system architecture.

==User statistics entries (Type 9)==

User lines report on an individual user's activity. These statistics include:
<ul>
<li>Final (logout) and partial statistics</li>

<li>Since-last and ordered index statistics</li>

<li>Performance statistics</li>
</ul>

Each user line starts with the following statistics:
ST $$$ USERID='userid' ACCOUNT='account'


The subtype, in this case PERFORMANCE, follows USERID and ACCOUNT statistics:
ST $$$ USERID='userid' ACCOUNT='account'
PERFORMANCE=n


The format of user statistics entries is shown in the following table:

<li><var class="term">uuuuu</var> is a 5-digit user number associated with the audit trail line. Leading zeros are suppressed.</li>
</ul>

In some cases, the account name appears as "NO USERID NO ACCOUNT". Statistics in this category are not chargeable to any one user and should be considered system overhead.

Final lines are recognized by the absence of an indicator for another type of line.

===Partial statistics===

Optional partial statistics, listed in the "Layout of user subtype X'00' and X'02' entries" table below, can be provided for a run up to a few minutes before a system failure that prevents normal termination and production of final user and system statistics. 

User partial statistics lines, such as the following, are made available for active users: 
ST $$$ ACCOUNT='NO ACCOUNT' PARTIAL=21 ...


Statistics accumulate either:
<ul>
<li>As long as the user is logged in</li>
</ul>

or
<ul>
<li>From the first terminal input to disconnection when a login is not required </li>
</ul>

Partial statistics are requested by setting the time interval, in minutes, between successive partial lines on User 0's parameter line with the <var>ACCTIM</var> parameter. <var>ACCTIM</var> must be nonzero. 

The contents of the statistics portion of the entry, starting at offset <code>40(28)</code>, depends upon the subtype of the entry. 

Partial statistics lines are indicated on the journal by the parameter <code>PARTIAL=n</code>, where <var class="term">n</var> is a counter from the beginning of the run. <code>PARTIAL=n</code> immediately follows the type parameter.

For subtypes X'00' (logout statistics), and X'02' (partial statistics), the layout of the remainder of the entry is shown in the following table. Each statistic in the table is: Length, 4; Data type, Binary. For the meaning of each statistic, see the [[#Description of statistics|Statistics with descriptions]] table.

==User since-last statistics==

===Since-last statistics===

Statistics are kept for each SOUL request, host language interface call, and a number of <var class="product">Model 204</var> system commands. When each request or command completes, a since-last statistics line is written. The line includes the <var>ACCOUNT</var> parameter at the beginning, followed by the <var>IODEV</var> parameter and the <var>LAST</var> parameter.

Several <var>MONITOR</var> commands produce displays containing the user's last or current activity in the <code>FUNC</code> column. When this activity completes, statistics are also written to CCAAUDIT and the activity is described in ST lines as <code>LAST='activity'</code>.

====Syntax====
ST $$$ USERID='userid' ACCOUNT='accountname' IODEV='devicetype' LAST='acty'

Where:

<var class="term">acty</var> can be one of the following:

===Since-last highwater marks===

The since-last statistics include highwater marks of various work tables used by SOUL requests. Values are reported in terms of the units in which each table is allocated. For example, QTBL is allocated in units of 16 bytes.

===Since-last in relation to final and partial statistics===

Many since-last statistics, such as CNCT, CPU, and DKRD, are also reported on user final and partial statistics lines. (See the [[#Description of statistics|Statistics with descriptions]] table.) The statistics on these lines are roughly equal to the sum of all of the preceding since-last statistics for the user.
Because since-last statistics are not maintained for every <var class="product">Model 204</var> command, final statistics are generally larger.

For subtype X'01' (since-last statistics), the layout of the remainder of the entry begins as shown in the following table.
For the meaning of each statistic in this table and in the [[#Conflict statistics|Layout of user subtype X'01' entries (CFRJRNL=0)]] table, see the [[#Description of statistics|Statistics with descriptions]] table.
The layout of the end of the entry depends on whether you chose to collect conflict statistics:
<ul>
<li>If you do not collect conflict statistics, the end of the entry is described in the [[#Conflict statistics|Layout of user subtype X'01' entries (CFRJRNL=0)]] table.</li>

<li>If you do collect conflict statistics, the end of the entry is described in the [[#Conflict statistics|Layout of user subtype X'81' entries (CFRJRNL=1)]] table. When you collect conflict statistics, the subtype changes to X'81'. </li>

===Conflict statistics===

Whether you are collecting conflict statistics determines the layout at the end of the entry. Two of the conflict statistics keep track of critical file-resource conflicts, and two keep track of record-locking conflicts. Whether these statistics are collected and journaled depends on settings of the parameters <var>[[CFRLOOK parameter|CFRLOOK]]</var> and <var>[[CFRJRNL parameter|CFRJRNL]]</var>.


These statistics are not displayed with the output of the <code>MONITOR SL</code> command. Instead, you can view them (with all the other since-last statistics) by issuing the <var>MONITOR</var> command with the keyword <var>CONFLICT</var>.

The remainder of the entry depends on the setting of <var>CFRJRNL</var>.

The following table shows the layout when <var>CFRJRNL</var> is set to 0: 
<table>
<caption>Layout of user subtype X'01' entries (CFRJRNL=0)</caption>
<tr class="head">
<th>Offset dec(hex)</th>

Note:
The conflict statistics, BLKCFRE, BLKRLK, WTCFR, and WTRLK, are inexact. Although a user might at times conflict with multiple other users, only the first conflict encountered is counted.

==User performance statistics==

Optional performance statistics lines provide information about the operation of the <var class="product">Model 204</var> scheduler during a short period of time. Information about the length of the scheduler queues, the number of active users and servers, and the queue distribution for each user, is obtained by sampling. 

A performance line starts with:
ST $$$ USERID='userid' ACCOUNT='accountname'
PERFORMANCE=n


===Parameters to activate performance statistics===

To request performance statistics, specify the number of samples to take between performance statistics lines (<var>RPTCNT</var> parameter) and the time interval between samples (<var>SMPLTIM</var> parameter) on User 0's parameter line. When you request scheduler and server performance data (<var>SMPLTIM</var> parameter), an asynchronous operating system task, called the performance subtask, is created. Both <var>RPTCNT</var> and <var>SMPLTIM</var> must be nonzero.

===Sampling===

The performance subtask spends most of its time in a wait state. Every <var>SMPLTIM</var> milliseconds, it records the current state of the system. Data from the most recent sample is available at an Online terminal through the <var>MONITOR</var> command, described in [[Controlling system operations (CCAIN)#ONLINE monitoring|ONLINE monitoring]]. 

The number of samples taken during a run (<var>RPTCNT</var>), times the number of users in the run (<var>NUSERS</var>), must be less than 4.2 million. In large systems that run for a very long period of time, the time interval between samples cannot be extremely short. If the limit is exceeded, an OC1 interrupt occurs when the SMPLS statistic value is calculated during the printing of the system statistics, either a performance or final line.

====Layout of performance statistics====

For subtype X'04' (performance statistics), the layout of the remainder of the entry is shown in the following table.
Each statistic in the table is: Length, 4; Data type, Binary. For the description of each statistic, see the [[#Description of statistics|Statistics with descriptions]] table.

==File statistics entries (Type 10)==

File statistics, summarized in the [[#File statistics journal records layout|File statistics entry formats]] table, are kept for every file opened during a run, including CCAGRP, CCASYS, and CCATEMP. The activity of a file for all users is summarized from the time the file is first opened until the last user issues a <var>CLOSE</var> command. The statistics appear after the last <var>CLOSE</var> command in lines that follow the date and time information (yyyydddhhmmssnnnsssuuuuu) with: 
ST $$$ FILE='filename'


System termination writes file statistics for each file still open at the end of the run.

===Final statistics===

A final statistics line similar to the following is produced when the last user of a file closes the file: 
ST $$$ FILE='PAYABLES'DKRD=25 DKRD=25 DKWR=15 REQ=3 RECADD=6 ...


===Partial statistics===

File partial statistics lines similar to the following are furnished for each open file: 
ST $$$ FILE='PAYABLES'PARTIAL=3 ...


===File statistics journal records layout===

File statistics entries have the format shown in the following table.
For a description of each statistic, see the [[#Description of statistics|Statistics with descriptions]] table.

==Text entries (Type 11, Type 13)==

Type 11 (X'0B') and Type 13 (X'0D') entries record most of the actual text of the audit trail.

===Noncontinued text entries, Type 11 (X'0B')===

Each Type 11 journal entry corresponds to one logical entry in the audit trail, even though it might generate more than one line of physical output in the audit trail. 

The format of a Type 11 entry is shown in the following table:

==System Management Facilities==

You can write certain statistics to the System Management Facilities (SMF) data set by: 
<ul>
<li>Setting the <var>[[SMFSLRN parameter|SMFSLRN]]</var> and <var>[[SMFLORN parameter|SMFLORN]]</var> parameters on the User 0 command line to activate the SMF feature. (z/OS and z/VM)</li>

<li>Modifying the program that processes the SMF data set to handle the records written by <var class="product">Model 204</var>. (z/VM only)</li>
</ul>

See the [[#z/VM requirements|z/VM requirements]] and the the [[#z/OS requirements|z/OS requirements]] sections for details.

Since-last statistics or logout statistics can be written concurrently with statistics that are written to the journal. Logout statistics are more complete than since-last statistics. Many more since-last records than logout records are usually written. 

If the operating system crashes before a user logs out, the SMF data set has a since-last record for every request run, but no logout record. 

File and system statistics cannot be written to the SMF data set.

During system initialization, <var class="product">Model 204</var> issues a message reporting the SMF system ID, the run's job name, the step name, and the JES ID. For operating systems other than z/OS, the JES ID is blank.

===z/VM requirements===

In the CMS interface to <var class="product">Model 204</var>, you can incorporate a user-written accounting exit that invokes the ACCTEXIT routine to process each statistics record as it is written. The following considerations apply:
<ul>
<li>Take care to preserve the CMS environment in which <var class="product">Model 204</var> is running. Do not change the contents of general registers 13 and 14.</li>

<li>You must specify the <var>SMFLORN</var> and/or <var>SMFSLRN</var> parameters on User 0's parameter line to activate accounting record production.</li>

<li>TEXT file for the ACCTEXIT module must be available on an accessed disk when generating M204CMS using M204GEN. For complete installation procedures, see the <var class="book">Rocket Model 204 z/VM Installation Guide</var>.</li>
</ul>

===z/OS requirements===

To write since-last SMF records in a z/OS environment, activate the SMF feature. 

To activate SMF, set the following parameters on User 0's parameter line: 
<ul>
<li>SMFSLRN — SMF record number for since-last records</li>

<li>SMFLORN — SMF record number for logout records </li>
</ul>

The following considerations apply:
<ul>
<li>Since-last SMF records are written only if the SMFSLRN parameter is set to a non-zero value at the beginning of the run.</li>

<li>Logout SMF records are written only if the SMFLORN parameter is set to a non-zero value at the beginning of the run.</li>

<li>If both parameters are set, each type of record is written.</li>
</ul>

SMF record numbers, which identify the record type to the programs that process the SMF data set, are written as part of the header of the SMF records. The record numbers must be between 128 and 255.

See the "System Management Facility record layout and statistics" section, which follows.

Using system statistics

2025-08-20T23:16:03Z

MMarshall:

==Overview==

The tables on this page are provided for your use in identifying and tracking statistics that are reported by <var class="product">Model 204</var> in various situations. The offsets, given in decimal and hexadecimal, are to help you locate particular statistics within statistical output. The length is in bytes.

The statistics are collected in the [[Tracking_system_activity_(CCAJRNL, CCAAUDIT, CCAJLOG)#Introducing CCAJRNL|CCAJRNL]] data set, or if allocated, in [[Tracking system activity (CCAJRNL, CCAAUDIT, CCAJLOG)#Introducing CCAAUDIT and CCAJLOG|CCAJLOG]]. The offsets in the tables below locate each statistic in the corresponding record. To accommodate sites that need to run <var class="product">Model 204</var> around the clock for many days at a time, space for most <var class="product">Model 204</var> statistics is a double word.

==Description of statistics==

The "Statistics with descriptions" table lists the statistics that are collected and that you can evaluate. It also describes the purpose of each statistic followed by the circumstances when you can collect the information and an offset in the journal record. 

To collect several statistics you must preset a parameter to a nonzero value. Statistics that require a parameter are also noted in the "Statistics with descriptions" table. The table in [[Tracking system activity (CCAJRNL, CCAAUDIT, CCAJLOG)#Setting parameters to collect certain statistics|Setting parameters to collect certain statistics]] lists those statistics with the required parameter. 

Tables, identified by type, later in this topic, describe the layouts of the various journal records.

==Recovery entries (Types 1-6)==

Entry types X'01' through X'06' contain information used for recovery. They follow the same general format as all other journal entries. There is no type X'07' journal entry. 

The format of the recovery entries is meaningful only in the context of the <var class="product">Model 204</var> ROLL FORWARD algorithm. However, entry types might be of interest in some statistics gathering applications, as follows: 
<table>
<tr class="head">
<th>Type </th>
<th>Contains recovery information from...</th>
</tr>

<tr>
<td>1 </td>
<td>Discontinuity</td>
</tr>

<tr>
<td>2 </td>
<td> Begin update unit.

More than one type 2 entry can be written for each update unit. The update unit number appears as a 4-byte binary number at offset 16(10).
</td>
</tr>

<tr>
<td>3 </td>
<td> End update unit.

The update unit number appears in the same format and location as the type 2 entry.
</td>
</tr>

<tr>
<td>4</td>
<td>File state information: opened, closed, dumped, file parameter list (FPL) page preimage logged or open at the time of a checkpoint</td>
</tr>

<tr>
<td>5 </td>
<td>Checkpoint</td>
</tr>

<tr>
<td>6 </td>
<td>File update </td>
</tr>
</table>

==System statistics entries (Type 8)==

Cumulative statistics, listed by offset in the [[#System performance statistics|Layout of system subtype X'02' entries]] table, are kept for the entire system. Final, partial, and performance system statistics are written to the journal during <var class="product">Model 204</var> termination in a line that begins with:
ST $$$ SYSTEM='version#'


For additional information about:
<ul>
<li>Using system statistics for performance monitoring, see [[Performance monitoring and tuning]]. </li>

<li>Disk buffer monitor statistics and parameters, see [[Performance monitoring and tuning#Disk buffer monitor statistics and parameters|Disk buffer monitor statistics and parameters]]. </li>
</ul>

===Final statistics===

The system final statistics line, similar to the following, is produced as part of system termination: 
ST $$$ SYSTEM='5A 'AUDIT=43 OUT=38 IN=14 WAIT=19 ...


===Partial statistics===

Statistics in a system partial statistics line, similar to the following, accumulate from the beginning of the run, if the User 0 <var>[[ACCTIM parameter|ACCTIM]]</var> parameter is nonzero: 
ST $$$ SYSTEM='6.1.0'PARTIAL=3 AUDIT=19 OUT=10 IN=5 WAIT=3 ...


===Performance statistics===

System performance statistic lines, similar to the following, are written if the User 0 <var>[[RPTCNT parameter|RPTCNT]]</var> and <var>[[SMPLTIM parameter|SMPLTIM]]</var> parameters are nonzero: 
ST $$$ SYSTEM='6.1.0' PERFORMANCE=n


The numbers determined at the performance sample points are averaged for the entire run. 

===Entry formats===

System statistics entries have the format shown in the following table: 
<table>
<caption>System statistics entry formats</caption>
<tr class="head">
<th>Offset dec(hex)</th>
<th>Length</th>
<th>Data type</th>
<th>Description</th>
</tr>

<tr>

<td align="right"> — </td>
<td align="right"> — </td>

Contents depend on subtypes, shown in tables in the following sections:
<ul>
<li>[[#System final and partial statistics|System final and partial statistics]]</li>

<li>[[#System performance statistics|System performance statistics]]</li>

<li>[[#Additional disk buffer monitor statistics|Additional disk buffer monitor statistics]]</li>

<li>[[#User since-last statistics|User since-last statistics]]</li>
</ul>
</td> </tr>
</table>

==System final and partial statistics==

For subtypes X'00' (final statistics) and X'01' (partial statistics), the layout of the remainder of the entry is shown in the following table.
For a description of each statistic, see the [[#Description of statistics|Statistics with descriptions]] table.
The following statistics are data type Binary. However, the length varies — either 4 or 8, to accommodate 64-bit system architecture.

==User statistics entries (Type 9)==

User lines report on an individual user's activity. These statistics include:
<ul>
<li>Final (logout) and partial statistics</li>

<li>Since-last and ordered index statistics</li>

<li>Performance statistics</li>
</ul>

Each user line starts with the following statistics:
ST $$$ USERID='userid' ACCOUNT='account'


The subtype, in this case PERFORMANCE, follows USERID and ACCOUNT statistics:
ST $$$ USERID='userid' ACCOUNT='account'
PERFORMANCE=n


The format of user statistics entries is shown in the following table:

==User final and partial statistics==

===Final (logout) statistics===

Final (logout) statistics, listed in the [[#Partial statistics|Layout of user subtype X'00' and X'02' entries]] table, summarize a user's activities since the last login. A LOGOUT statistics line, such as the following, is written after each logout if the parameter following ACCOUNT is not PARTIAL, LAST, or PERFORMANCE: 
yydddhhmmssnnnsssuuuuu ST $$$ ACCOUNT='NO ACCOUNT' SQRD=5 ...

<ul>
<li><var class="term">yyddd</var> is the year and Julian day.</li>

<li><var class="term">hhmmss</var> is the time of day in hours, minutes, and seconds.</li>

<li><var class="term">nnn</var> is a counter to distinguish lines produced in the same second.</li>

<li><var class="term">sss</var> is the number of the server currently handling the user. Leading zeros are suppressed.
</li>

<li><var class="term">uuuuu</var> is a 5-digit user number associated with the audit trail line. Leading zeros are suppressed.</li>
</ul>

In some cases, the account name appears as "NO USERID NO ACCOUNT". Statistics in this category are not chargeable to any one user and should be considered system overhead.

Final lines are recognized by the absence of an indicator for another type of line.

===Partial statistics===

Optional partial statistics, listed in the "Layout of user subtype X'00' and X'02' entries" table below, can be provided for a run up to a few minutes before a system failure that prevents normal termination and production of final user and system statistics. 

User partial statistics lines, such as the following, are made available for active users: 
ST $$$ ACCOUNT='NO ACCOUNT' PARTIAL=21 ...


Statistics accumulate either:
<ul>
<li>As long as the user is logged in</li>
</ul>

or
<ul>
<li>From the first terminal input to disconnection when a login is not required </li>
</ul>

Partial statistics are requested by setting the time interval, in minutes, between successive partial lines on User 0's parameter line with the <var>ACCTIM</var> parameter. <var>ACCTIM</var> must be nonzero. 

The contents of the statistics portion of the entry, starting at offset <code>40(28)</code>, depends upon the subtype of the entry. 

Partial statistics lines are indicated on the journal by the parameter <code>PARTIAL=n</code>, where <var class="term">n</var> is a counter from the beginning of the run. <code>PARTIAL=n</code> immediately follows the type parameter.

For subtypes X'00' (logout statistics), and X'02' (partial statistics), the layout of the remainder of the entry is shown in the following table. Each statistic in the table is: Length, 4; Data type, Binary. For the meaning of each statistic, see the [[#Description of statistics|Statistics with descriptions]] table.

==User since-last statistics==

===Since-last statistics===

Statistics are kept for each SOUL request, host language interface call, and a number of <var class="product">Model 204</var> system commands. When each request or command completes, a since-last statistics line is written. The line includes the <var>ACCOUNT</var> parameter at the beginning, followed by the <var>IODEV</var> parameter and the <var>LAST</var> parameter.

Several <var>MONITOR</var> commands produce displays containing the user's last or current activity in the <code>FUNC</code> column. When this activity completes, statistics are also written to CCAAUDIT and the activity is described in ST lines as <code>LAST='activity'</code>.

====Syntax====
ST $$$ USERID='userid' ACCOUNT='accountname' IODEV='devicetype' LAST='acty'

Where:

<var class="term">acty</var> can be one of the following:

===Since-last highwater marks===

The since-last statistics include highwater marks of various work tables used by SOUL requests. Values are reported in terms of the units in which each table is allocated. For example, QTBL is allocated in units of 16 bytes.

===Since-last in relation to final and partial statistics===

Many since-last statistics, such as CNCT, CPU, and DKRD, are also reported on user final and partial statistics lines. (See the [[#Description of statistics|Statistics with descriptions]] table.) The statistics on these lines are roughly equal to the sum of all of the preceding since-last statistics for the user.
Because since-last statistics are not maintained for every <var class="product">Model 204</var> command, final statistics are generally larger.

For subtype X'01' (since-last statistics), the layout of the remainder of the entry begins as shown in the following table.
For the meaning of each statistic in this table and in the [[#Conflict statistics|Layout of user subtype X'01' entries (CFRJRNL=0)]] table, see the [[#Description of statistics|Statistics with descriptions]] table.
The layout of the end of the entry depends on whether you chose to collect conflict statistics:
<ul>
<li>If you do not collect conflict statistics, the end of the entry is described in the [[#Conflict statistics|Layout of user subtype X'01' entries (CFRJRNL=0)]] table.</li>

<li>If you do collect conflict statistics, the end of the entry is described in the [[#Conflict statistics|Layout of user subtype X'81' entries (CFRJRNL=1)]] table. When you collect conflict statistics, the subtype changes to X'81'. </li>

===Conflict statistics===

Whether you are collecting conflict statistics determines the layout at the end of the entry. Two of the conflict statistics keep track of critical file-resource conflicts, and two keep track of record-locking conflicts. Whether these statistics are collected and journaled depends on settings of the parameters <var>[[CFRLOOK parameter|CFRLOOK]]</var> and <var>[[CFRJRNL parameter|CFRJRNL]]</var>.


These statistics are not displayed with the output of the <code>MONITOR SL</code> command. Instead, you can view them (with all the other since-last statistics) by issuing the <var>MONITOR</var> command with the keyword <var>CONFLICT</var>.

The remainder of the entry depends on the setting of <var>CFRJRNL</var>.

The following table shows the layout when <var>CFRJRNL</var> is set to 0: 
<table>
<caption>Layout of user subtype X'01' entries (CFRJRNL=0)</caption>
<tr class="head">
<th>Offset dec(hex)</th>

The following table shows the layout when <var>CFRJRNL</var> is set to 1. It reflects the change in offset and that the user subtypes are now X'81' entries.

Note:
The conflict statistics, BLKCFRE, BLKRLK, WTCFR, and WTRLK, are inexact. Although a user might at times conflict with multiple other users, only the first conflict encountered is counted.

==User performance statistics==

Optional performance statistics lines provide information about the operation of the <var class="product">Model 204</var> scheduler during a short period of time. Information about the length of the scheduler queues, the number of active users and servers, and the queue distribution for each user, is obtained by sampling. 

A performance line starts with:
ST $$$ USERID='userid' ACCOUNT='accountname'
PERFORMANCE=n


===Parameters to activate performance statistics===

To request performance statistics, specify the number of samples to take between performance statistics lines (<var>RPTCNT</var> parameter) and the time interval between samples (<var>SMPLTIM</var> parameter) on User 0's parameter line. When you request scheduler and server performance data (<var>SMPLTIM</var> parameter), an asynchronous operating system task, called the performance subtask, is created. Both <var>RPTCNT</var> and <var>SMPLTIM</var> must be nonzero.

===Sampling===

The performance subtask spends most of its time in a wait state. Every <var>SMPLTIM</var> milliseconds, it records the current state of the system. Data from the most recent sample is available at an Online terminal through the <var>MONITOR</var> command, described in [[Controlling system operations (CCAIN)#ONLINE monitoring|ONLINE monitoring]]. 

The number of samples taken during a run (<var>RPTCNT</var>), times the number of users in the run (<var>NUSERS</var>), must be less than 4.2 million. In large systems that run for a very long period of time, the time interval between samples cannot be extremely short. If the limit is exceeded, an OC1 interrupt occurs when the SMPLS statistic value is calculated during the printing of the system statistics, either a performance or final line.

====Layout of performance statistics====

For subtype X'04' (performance statistics), the layout of the remainder of the entry is shown in the following table.
Each statistic in the table is: Length, 4; Data type, Binary. For the description of each statistic, see the [[#Description of statistics|Statistics with descriptions]] table.

==File statistics entries (Type 10)==

File statistics, summarized in the [[#File statistics journal records layout|File statistics entry formats]] table, are kept for every file opened during a run, including CCAGRP, CCASYS, and CCATEMP. The activity of a file for all users is summarized from the time the file is first opened until the last user issues a <var>CLOSE</var> command. The statistics appear after the last <var>CLOSE</var> command in lines that follow the date and time information (yyyydddhhmmssnnnsssuuuuu) with: 
ST $$$ FILE='filename'


System termination writes file statistics for each file still open at the end of the run.

===Final statistics===

A final statistics line similar to the following is produced when the last user of a file closes the file: 
ST $$$ FILE='PAYABLES'DKRD=25 DKRD=25 DKWR=15 REQ=3 RECADD=6 ...


===Partial statistics===

File partial statistics lines similar to the following are furnished for each open file: 
ST $$$ FILE='PAYABLES'PARTIAL=3 ...


===File statistics journal records layout===

File statistics entries have the format shown in the following table.
For a description of each statistic, see the [[#Description of statistics|Statistics with descriptions]] table.

==Text entries (Type 11, Type 13)==

Type 11 (X'0B') and Type 13 (X'0D') entries record most of the actual text of the audit trail.

===Noncontinued text entries, Type 11 (X'0B')===

Each Type 11 journal entry corresponds to one logical entry in the audit trail, even though it might generate more than one line of physical output in the audit trail. 

The format of a Type 11 entry is shown in the following table:

==System Management Facilities==

You can write certain statistics to the System Management Facilities (SMF) data set by: 
<ul>
<li>Setting the <var>[[SMFSLRN parameter|SMFSLRN]]</var> and <var>[[SMFLORN parameter|SMFLORN]]</var> parameters on the User 0 command line to activate the SMF feature. (z/OS and z/VM)</li>

<li>Modifying the program that processes the SMF data set to handle the records written by <var class="product">Model 204</var>. (z/VM only)</li>
</ul>

See the [[#z/VM requirements|z/VM requirements]] and the the [[#z/OS requirements|z/OS requirements]] sections for details.

Since-last statistics or logout statistics can be written concurrently with statistics that are written to the journal. Logout statistics are more complete than since-last statistics. Many more since-last records than logout records are usually written. 

If the operating system crashes before a user logs out, the SMF data set has a since-last record for every request run, but no logout record. 

File and system statistics cannot be written to the SMF data set.

During system initialization, <var class="product">Model 204</var> issues a message reporting the SMF system ID, the run's job name, the step name, and the JES ID. For operating systems other than z/OS, the JES ID is blank.

===z/VM requirements===

In the CMS interface to <var class="product">Model 204</var>, you can incorporate a user-written accounting exit that invokes the ACCTEXIT routine to process each statistics record as it is written. The following considerations apply:
<ul>
<li>Take care to preserve the CMS environment in which <var class="product">Model 204</var> is running. Do not change the contents of general registers 13 and 14.</li>

<li>You must specify the <var>SMFLORN</var> and/or <var>SMFSLRN</var> parameters on User 0's parameter line to activate accounting record production.</li>

<li>TEXT file for the ACCTEXIT module must be available on an accessed disk when generating M204CMS using M204GEN. For complete installation procedures, see the <var class="book">Rocket Model 204 z/VM Installation Guide</var>.</li>
</ul>

===z/OS requirements===

To write since-last SMF records in a z/OS environment, activate the SMF feature. 

To activate SMF, set the following parameters on User 0's parameter line: 
<ul>
<li>SMFSLRN — SMF record number for since-last records</li>

<li>SMFLORN — SMF record number for logout records </li>
</ul>

The following considerations apply:
<ul>
<li>Since-last SMF records are written only if the SMFSLRN parameter is set to a non-zero value at the beginning of the run.</li>

<li>Logout SMF records are written only if the SMFLORN parameter is set to a non-zero value at the beginning of the run.</li>

<li>If both parameters are set, each type of record is written.</li>
</ul>

SMF record numbers, which identify the record type to the programs that process the SMF data set, are written as part of the header of the SMF records. The record numbers must be between 128 and 255.

Using system statistics

2025-08-20T22:00:06Z

MMarshall:

==Overview==

The tables on this page are provided for your use in identifying and tracking statistics that are reported by <var class="product">Model 204</var> in various situations. The offsets, given in decimal and hexadecimal, are to help you locate particular statistics within statistical output. The length is in bytes.

The statistics are collected in the [[Tracking_system_activity_(CCAJRNL, CCAAUDIT, CCAJLOG)#Introducing CCAJRNL|CCAJRNL]] data set, or if allocated, in [[Tracking system activity (CCAJRNL, CCAAUDIT, CCAJLOG)#Introducing CCAAUDIT and CCAJLOG|CCAJLOG]]. The offsets in the tables below locate each statistic in the corresponding record. To accommodate sites that need to run <var class="product">Model 204</var> around the clock for many days at a time, space for most <var class="product">Model 204</var> statistics is a double word.

==Description of statistics==

The "Statistics with descriptions" table lists the statistics that are collected and that you can evaluate. It also describes the purpose of each statistic followed by the circumstances when you can collect the information and an offset in the journal record. 

To collect several statistics you must preset a parameter to a nonzero value. Statistics that require a parameter are also noted in the "Statistics with descriptions" table. The table in [[Tracking system activity (CCAJRNL, CCAAUDIT, CCAJLOG)#Setting parameters to collect certain statistics|Setting parameters to collect certain statistics]] lists those statistics with the required parameter. 

Tables, identified by type, later in this topic, describe the layouts of the various journal records.

==Header and trailer entries (Type 0)==

Each journal block begins with a header record and ends with a trailer record.

===Header entries (Type 0)===

Header entries have the format shown in the following table: 
<table>
<caption style="margin-right:6em">Header entry formats</caption>
<tr class="head">
<th>Offset dec(hex)</th>
<th>Length</th>
<th>Data type</th>
<th>Description</th>

<ul>
<li>If the flag byte at offset 3 of type 00 has the X'02' bit on, then it is a header record from <var class="product">Model 204</var> version 7.4.0 or later with its length at offset X'1A'.</li>

<li>If that flag byte has the X'01' bit on, then the header is from version 7.1.0 and is 26 bytes in length. </li>

<li>If neither of those bits is on, then the header is a from a pre-7.1.0 version and is 16 bytes in length.</li>
</ul>

===Recovery flags===

Flags used by recovery can have the value of X'00' or a sum of any of the following: 
<table>
<tr class="head">
<th>Value</th>
<th>Block contains these records...</th>
</tr>

<tr>
<td>X'80'</td>
<td>Type 1</td>
</tr>

<tr>
<td>X'40'</td>
<td>Type 2</td>
</tr>

<tr>
<td>X'20'</td>
<td>Type 3</td>
</tr>

<tr>

<td>Type 4</td>
</tr>

<tr>
<td>X'08'</td>
<td>Type 5</td>
</tr>

<tr>
<td>X'04'</td>
<td>Type 6</td>
</tr>
</table>

===Sequence numbers===

The sequence number represents the number of each journal record, starting at 0 and increasing by 1. A merged journal (output of the MERGEJ utility) sequence number consists of a 2-byte hexadecimal number at offset 12(0C), which indicates the input file this journal record came from, and a 2-byte hexadecimal field at offset 14(0E), which indicates the sequence within the INPUT journal.

===Trailer entries (Type 0)===

Trailer entries have the format shown in the following table: 
<table>
<caption>Trailer entry formats</caption>
<tr class="head">
<th>Offset dec(hex)</th>
<th>Length</th>
<th>Data type</th>
<th>Description</th>
</tr>

<tr>
<td> 0(0)</td>
<td align="right"> 2</td>
<td> Binary</td>
<td>Length of entry = X'000C'</td>

<td>Julian date = 0CYYDDDF</td>
</tr>

<tr>
<td> 8(8)</td>
<td align="right"> 4</td>
<td>Unsigned packed data </td>
<td>Time = HHMMSSTH</td>
</tr>
</table>

==Recovery entries (Types 1-6)==

Entry types X'01' through X'06' contain information used for recovery. They follow the same general format as all other journal entries. There is no type X'07' journal entry. 

The format of the recovery entries is meaningful only in the context of the <var class="product">Model 204</var> ROLL FORWARD algorithm. However, entry types might be of interest in some statistics gathering applications, as follows: 
<table>
<tr class="head">
<th>Type </th>
<th>Contains recovery information from...</th>
</tr>

<tr>
<td>1 </td>
<td>Discontinuity</td>
</tr>

<tr>
<td>2 </td>
<td> Begin update unit.

More than one type 2 entry can be written for each update unit. The update unit number appears as a 4-byte binary number at offset 16(10).
</td>
</tr>

<tr>
<td>3 </td>
<td> End update unit.

The update unit number appears in the same format and location as the type 2 entry.
</td>
</tr>

<tr>
<td>4</td>
<td>File state information: opened, closed, dumped, file parameter list (FPL) page preimage logged or open at the time of a checkpoint</td>
</tr>

<tr>
<td>5 </td>
<td>Checkpoint</td>
</tr>

<tr>
<td>6 </td>
<td>File update </td>
</tr>
</table>

==System statistics entries (Type 8)==

Cumulative statistics, listed by offset in the [[#System performance statistics|Layout of system subtype X'02' entries]] table, are kept for the entire system. Final, partial, and performance system statistics are written to the journal during <var class="product">Model 204</var> termination in a line that begins with:
ST $$$ SYSTEM='version#'


For additional information about:
<ul>
<li>Using system statistics for performance monitoring, see [[Performance monitoring and tuning]]. </li>

<li>Disk buffer monitor statistics and parameters, see [[Performance monitoring and tuning#Disk buffer monitor statistics and parameters|Disk buffer monitor statistics and parameters]]. </li>
</ul>

===Final statistics===

The system final statistics line, similar to the following, is produced as part of system termination: 
ST $$$ SYSTEM='5A 'AUDIT=43 OUT=38 IN=14 WAIT=19 ...


===Partial statistics===

Statistics in a system partial statistics line, similar to the following, accumulate from the beginning of the run, if the User 0 <var>[[ACCTIM parameter|ACCTIM]]</var> parameter is nonzero: 
ST $$$ SYSTEM='6.1.0'PARTIAL=3 AUDIT=19 OUT=10 IN=5 WAIT=3 ...


===Performance statistics===

System performance statistic lines, similar to the following, are written if the User 0 <var>[[RPTCNT parameter|RPTCNT]]</var> and <var>[[SMPLTIM parameter|SMPLTIM]]</var> parameters are nonzero: 
ST $$$ SYSTEM='6.1.0' PERFORMANCE=n


The numbers determined at the performance sample points are averaged for the entire run. 

===Entry formats===

System statistics entries have the format shown in the following table: 
<table>
<caption>System statistics entry formats</caption>
<tr class="head">
<th>Offset dec(hex)</th>
<th>Length</th>
<th>Data type</th>
<th>Description</th>
</tr>

<tr>

Contents depend on subtypes, shown in tables in the following sections:
<ul>
<li>[[#System final and partial statistics|System final and partial statistics]]</li>

<li>[[#System performance statistics|System performance statistics]]</li>

<li>[[#Additional disk buffer monitor statistics|Additional disk buffer monitor statistics]]</li>

<li>[[#User since-last statistics|User since-last statistics]]</li>
</ul>
</td> </tr>
</table>

==System final and partial statistics==

For subtypes X'00' (final statistics) and X'01' (partial statistics), the layout of the remainder of the entry is shown in the following table.
For a description of each statistic, see the [[#Description of statistics|Statistics with descriptions]] table.
The following statistics are data type Binary. However, the length varies — either 4 or 8, to accommodate 64-bit system architecture.

==User statistics entries (Type 9)==

User lines report on an individual user's activity. These statistics include:
<ul>
<li>Final (logout) and partial statistics</li>

<li>Since-last and ordered index statistics</li>

<li>Performance statistics</li>
</ul>

Each user line starts with the following statistics:
ST $$$ USERID='userid' ACCOUNT='account'


The subtype, in this case PERFORMANCE, follows USERID and ACCOUNT statistics:
ST $$$ USERID='userid' ACCOUNT='account'
PERFORMANCE=n


The format of user statistics entries is shown in the following table:

==User final and partial statistics==

===Final (logout) statistics===

Final (logout) statistics, listed in the [[#Partial statistics|Layout of user subtype X'00' and X'02' entries]] table, summarize a user's activities since the last login. A LOGOUT statistics line, such as the following, is written after each logout if the parameter following ACCOUNT is not PARTIAL, LAST, or PERFORMANCE: 
yydddhhmmssnnnsssuuuuu ST $$$ ACCOUNT='NO ACCOUNT' SQRD=5 ...

<ul>
<li><var class="term">yyddd</var> is the year and Julian day.</li>

<li><var class="term">hhmmss</var> is the time of day in hours, minutes, and seconds.</li>

<li><var class="term">nnn</var> is a counter to distinguish lines produced in the same second.</li>

<li><var class="term">sss</var> is the number of the server currently handling the user. Leading zeros are suppressed.
</li>

<li><var class="term">uuuuu</var> is a 5-digit user number associated with the audit trail line. Leading zeros are suppressed.</li>
</ul>

In some cases, the account name appears as "NO USERID NO ACCOUNT". Statistics in this category are not chargeable to any one user and should be considered system overhead.

Final lines are recognized by the absence of an indicator for another type of line.

===Partial statistics===

Optional partial statistics, listed in the "Layout of user subtype X'00' and X'02' entries" table below, can be provided for a run up to a few minutes before a system failure that prevents normal termination and production of final user and system statistics. 

User partial statistics lines, such as the following, are made available for active users: 
ST $$$ ACCOUNT='NO ACCOUNT' PARTIAL=21 ...


Statistics accumulate either:
<ul>
<li>As long as the user is logged in</li>
</ul>

or
<ul>
<li>From the first terminal input to disconnection when a login is not required </li>
</ul>

Partial statistics are requested by setting the time interval, in minutes, between successive partial lines on User 0's parameter line with the <var>ACCTIM</var> parameter. <var>ACCTIM</var> must be nonzero. 

The contents of the statistics portion of the entry, starting at offset <code>40(28)</code>, depends upon the subtype of the entry. 

Partial statistics lines are indicated on the journal by the parameter <code>PARTIAL=n</code>, where <var class="term">n</var> is a counter from the beginning of the run. <code>PARTIAL=n</code> immediately follows the type parameter.

For subtypes X'00' (logout statistics), and X'02' (partial statistics), the layout of the remainder of the entry is shown in the following table. Each statistic in the table is: Length, 4; Data type, Binary. For the meaning of each statistic, see the [[#Description of statistics|Statistics with descriptions]] table.

==User since-last statistics==

===Since-last statistics===

Statistics are kept for each SOUL request, host language interface call, and a number of <var class="product">Model 204</var> system commands. When each request or command completes, a since-last statistics line is written. The line includes the <var>ACCOUNT</var> parameter at the beginning, followed by the <var>IODEV</var> parameter and the <var>LAST</var> parameter.

Several <var>MONITOR</var> commands produce displays containing the user's last or current activity in the <code>FUNC</code> column. When this activity completes, statistics are also written to CCAAUDIT and the activity is described in ST lines as <code>LAST='activity'</code>.

====Syntax====
ST $$$ USERID='userid' ACCOUNT='accountname' IODEV='devicetype' LAST='acty'

Where:

<var class="term">acty</var> can be one of the following:

===Since-last highwater marks===

The since-last statistics include highwater marks of various work tables used by SOUL requests. Values are reported in terms of the units in which each table is allocated. For example, QTBL is allocated in units of 16 bytes.

===Since-last in relation to final and partial statistics===

Many since-last statistics, such as CNCT, CPU, and DKRD, are also reported on user final and partial statistics lines. (See the [[#Description of statistics|Statistics with descriptions]] table.) The statistics on these lines are roughly equal to the sum of all of the preceding since-last statistics for the user.
Because since-last statistics are not maintained for every <var class="product">Model 204</var> command, final statistics are generally larger.

For subtype X'01' (since-last statistics), the layout of the remainder of the entry begins as shown in the following table.
For the meaning of each statistic in this table and in the [[#Conflict statistics|Layout of user subtype X'01' entries (CFRJRNL=0)]] table, see the [[#Description of statistics|Statistics with descriptions]] table.
The layout of the end of the entry depends on whether you chose to collect conflict statistics:
<ul>
<li>If you do not collect conflict statistics, the end of the entry is described in the [[#Conflict statistics|Layout of user subtype X'01' entries (CFRJRNL=0)]] table.</li>

<li>If you do collect conflict statistics, the end of the entry is described in the [[#Conflict statistics|Layout of user subtype X'81' entries (CFRJRNL=1)]] table. When you collect conflict statistics, the subtype changes to X'81'. </li>

===Conflict statistics===

Whether you are collecting conflict statistics determines the layout at the end of the entry. Two of the conflict statistics keep track of critical file-resource conflicts, and two keep track of record-locking conflicts. Whether these statistics are collected and journaled depends on settings of the parameters <var>[[CFRLOOK parameter|CFRLOOK]]</var> and <var>[[CFRJRNL parameter|CFRJRNL]]</var>.


These statistics are not displayed with the output of the <code>MONITOR SL</code> command. Instead, you can view them (with all the other since-last statistics) by issuing the <var>MONITOR</var> command with the keyword <var>CONFLICT</var>.

The remainder of the entry depends on the setting of <var>CFRJRNL</var>.

The following table shows the layout when <var>CFRJRNL</var> is set to 0: 
<table>
<caption>Layout of user subtype X'01' entries (CFRJRNL=0)</caption>
<tr class="head">
<th>Offset dec(hex)</th>

Note:
The conflict statistics, BLKCFRE, BLKRLK, WTCFR, and WTRLK, are inexact. Although a user might at times conflict with multiple other users, only the first conflict encountered is counted.

==User performance statistics==

Optional performance statistics lines provide information about the operation of the <var class="product">Model 204</var> scheduler during a short period of time. Information about the length of the scheduler queues, the number of active users and servers, and the queue distribution for each user, is obtained by sampling. 

A performance line starts with:
ST $$$ USERID='userid' ACCOUNT='accountname'
PERFORMANCE=n


===Parameters to activate performance statistics===

To request performance statistics, specify the number of samples to take between performance statistics lines (<var>RPTCNT</var> parameter) and the time interval between samples (<var>SMPLTIM</var> parameter) on User 0's parameter line. When you request scheduler and server performance data (<var>SMPLTIM</var> parameter), an asynchronous operating system task, called the performance subtask, is created. Both <var>RPTCNT</var> and <var>SMPLTIM</var> must be nonzero.

===Sampling===

The performance subtask spends most of its time in a wait state. Every <var>SMPLTIM</var> milliseconds, it records the current state of the system. Data from the most recent sample is available at an Online terminal through the <var>MONITOR</var> command, described in [[Controlling system operations (CCAIN)#ONLINE monitoring|ONLINE monitoring]]. 

The number of samples taken during a run (<var>RPTCNT</var>), times the number of users in the run (<var>NUSERS</var>), must be less than 4.2 million. In large systems that run for a very long period of time, the time interval between samples cannot be extremely short. If the limit is exceeded, an OC1 interrupt occurs when the SMPLS statistic value is calculated during the printing of the system statistics, either a performance or final line.

====Layout of performance statistics====

For subtype X'04' (performance statistics), the layout of the remainder of the entry is shown in the following table.
Each statistic in the table is: Length, 4; Data type, Binary. For the description of each statistic, see the [[#Description of statistics|Statistics with descriptions]] table.

==File statistics entries (Type 10)==

File statistics, summarized in the [[#File statistics journal records layout|File statistics entry formats]] table, are kept for every file opened during a run, including CCAGRP, CCASYS, and CCATEMP. The activity of a file for all users is summarized from the time the file is first opened until the last user issues a <var>CLOSE</var> command. The statistics appear after the last <var>CLOSE</var> command in lines that follow the date and time information (yyyydddhhmmssnnnsssuuuuu) with: 
ST $$$ FILE='filename'


System termination writes file statistics for each file still open at the end of the run.

===Final statistics===

A final statistics line similar to the following is produced when the last user of a file closes the file: 
ST $$$ FILE='PAYABLES'DKRD=25 DKRD=25 DKWR=15 REQ=3 RECADD=6 ...


===Partial statistics===

File partial statistics lines similar to the following are furnished for each open file: 
ST $$$ FILE='PAYABLES'PARTIAL=3 ...


===File statistics journal records layout===

File statistics entries have the format shown in the following table.
For a description of each statistic, see the [[#Description of statistics|Statistics with descriptions]] table.

==Text entries (Type 11, Type 13)==

Type 11 (X'0B') and Type 13 (X'0D') entries record most of the actual text of the audit trail.

===Noncontinued text entries, Type 11 (X'0B')===

Each Type 11 journal entry corresponds to one logical entry in the audit trail, even though it might generate more than one line of physical output in the audit trail. 

The format of a Type 11 entry is shown in the following table:

==System Management Facilities==

You can write certain statistics to the System Management Facilities (SMF) data set by: 
<ul>
<li>Setting the <var>[[SMFSLRN parameter|SMFSLRN]]</var> and <var>[[SMFLORN parameter|SMFLORN]]</var> parameters on the User 0 command line to activate the SMF feature. (z/OS and z/VM)</li>

<li>Modifying the program that processes the SMF data set to handle the records written by <var class="product">Model 204</var>. (z/VM only)</li>
</ul>

See the [[#z/VM requirements|z/VM requirements]] and the the [[#z/OS requirements|z/OS requirements]] sections for details.

Since-last statistics or logout statistics can be written concurrently with statistics that are written to the journal. Logout statistics are more complete than since-last statistics. Many more since-last records than logout records are usually written. 

If the operating system crashes before a user logs out, the SMF data set has a since-last record for every request run, but no logout record. 

File and system statistics cannot be written to the SMF data set.

During system initialization, <var class="product">Model 204</var> issues a message reporting the SMF system ID, the run's job name, the step name, and the JES ID. For operating systems other than z/OS, the JES ID is blank.

===z/VM requirements===

In the CMS interface to <var class="product">Model 204</var>, you can incorporate a user-written accounting exit that invokes the ACCTEXIT routine to process each statistics record as it is written. The following considerations apply:
<ul>
<li>Take care to preserve the CMS environment in which <var class="product">Model 204</var> is running. Do not change the contents of general registers 13 and 14.</li>

<li>You must specify the <var>SMFLORN</var> and/or <var>SMFSLRN</var> parameters on User 0's parameter line to activate accounting record production.</li>

<li>TEXT file for the ACCTEXIT module must be available on an accessed disk when generating M204CMS using M204GEN. For complete installation procedures, see the <var class="book">Rocket Model 204 z/VM Installation Guide</var>.</li>
</ul>

===z/OS requirements===

To write since-last SMF records in a z/OS environment, activate the SMF feature. 

To activate SMF, set the following parameters on User 0's parameter line: 
<ul>
<li>SMFSLRN — SMF record number for since-last records</li>

<li>SMFLORN — SMF record number for logout records </li>
</ul>

The following considerations apply:
<ul>
<li>Since-last SMF records are written only if the SMFSLRN parameter is set to a non-zero value at the beginning of the run.</li>

<li>Logout SMF records are written only if the SMFLORN parameter is set to a non-zero value at the beginning of the run.</li>

<li>If both parameters are set, each type of record is written.</li>
</ul>

SMF record numbers, which identify the record type to the programs that process the SMF data set, are written as part of the header of the SMF records. The record numbers must be between 128 and 255.

See the "System Management Facility record layout and statistics" section, which follows.
