Retrieve subsystem's statistics into string
Note: Many $functions have been deprecated in favor of Object Oriented methods. There is currently no OO equivalent for the $SsStat function.
This function allows retrieval of a specific subsystem's statistics into a string.
Syntax
%string = $SsStat(stat_list, subsystem_name)
| %string | A string of data. If the string contains exactly four bytes, it is a binary error code.
Otherwise, the first four bytes contain the unsigned binary number of milliseconds that the Online has been up. This provides a convenient number for calculating rates for the statistics. The next ten bytes contain the blank-padded file name, then follow two bytes containing the binary file number. This means that the actual statistical data starts at offset 16 (byte number 17) in the result string. |
|---|---|
| stat_list | A string of blank delimited words indicating the statistics to be returned. The length of each returned statistic is always a multiple of 4 bytes. This facilitates the use of $StatD with the returned string.
For more information about available statistics, see the SirMon M204wiki pages. |
| subsystem_name | The name of the subsystem for which data is to be returned. |
Return codes
-5 Required parameter not specified -12 Invalid parameter (argument 2 > NUSERS, or invalid name in stat_list) -13 STAT not linked in -14 Result string would be longer than 255 bytes -15 Subsystem not active
Example
The following program displays some totals for subsystem SIRMON.
B %DATA IS STRING LEN 255 %DATA = $SsStat('NUSER RESEVAL RESSWCH', 'SIRMON') IF $LEN(%DATA) = 4 THEN PRINT '$SSSTAT ERROR... RC = ' WITH - $UNBIN(%DATA) STOP END IF PRINT 'SUBSYSNAME = ' WITH $SUBSTR(%DATA, 5, 10) PRINT 'NUSER = ' WITH - $UNBIN( $SUBSTR(%DATA, 17, 4) ) PRINT 'RESEVAL = ' WITH - $UNBIN( $SUBSTR(%DATA, 21, 4) ) PRINT 'RESSWCH = ' WITH - $UNBIN( $SUBSTR(%DATA, 25, 4) ) END
