Revision as of 21:13, 2 November 2015

Option 3 from the SirMon main menu presents a menu of user statistics screens. This menu is also accessible by entering =3 in the command line of any SirMon screen.

Selecting any option from this menu transfers the user into a "scrollable screen" (see Scrollable screen format displaying specific statistics for all users in an Online system. The PF1 key from such a screen displays definitions for the presented statistics.

User Monitor menu

3.U Update the selection menu	Allows `SirMon` administrators to customize the User Monitor menu.
3.A User AD-HOC	An adhoc view of user statistics specific to each `SirMon` user.
3.1 Resource Usage	Broad measurements of users' consumption of CPU and I/O activity.
3.2 User State Display	Displays users state, wait type and other measures to indicate their level of activity.
3.3 Resource Usage and Subsys	Various resource consumption statistics and the current subsystem for each user.
3.4 Disk Buffer Usage	Various DKxxx statistics for each user.
3.5 Misc. Resource Usage	Aggregate measures of activity, making it easy to spot significant resource consumers.
3.6 Record Locking Table Usage	Statistics useful in determining utilization of the record locking table and highlighting poor enqueueing behaviour in applications.
3.7 Critical File Resources	Detailed statistics providing information about conflicts on critical file resources.

As many as 25 locally defined screens may also be accessed from the User Monitor menu. These screens are defined by a SirMon administrator as described in SirMon custom screens.

A number of special commands allow screen positioning and selection when viewing user statistics.

NO xxxxx	Positions the screen at the specified user number.
ACCOUNT xxxxxxx	xxxxxxxx is any valid wildcard string. This restricts the display to users with account ids that match the specified pattern. For example, this command limits the display to account IDs that begin with the letters "AB": ACCOUNT AB*
CHKP	Restricts the display to users that have an inflight updating transaction, hence preventing checkpoints. A checkpoint does not have to be in progress for this option to perform the indicated restriction, but if nobody is holding an open updating transaction, the display will be empty.
FILE xxxxxxxx	Restricts the display to users that have file xxxxxxxx open. Wildcards may not be used in the file name.
IODEV xxx	Restricts the display to users connected to the `Model 204` online via the specified IO device type. Wildcards are not allowed in the IODEV specification.
PNAME xxxxxxxx	This restricts the display to users currently running any procedure whose name matches the specified pattern. For example, this command limits the display to users running any procedure whose name ends with the letters "MENU": PNAME *MENU
SUBSYS xxxxxxxx	This restricts the display to users in any subsystem that matches the specified pattern. For example, this command limits the display to users in any subsystem that begins with the letters "TEST": SUBSYS TEST*
TERMID xxxxxxx	This restricts the display to users with terminal ids that match the specified pattern. For example, this command limits the display to terminal ids that begin with the letters "VT": TERMID VT*
USER xxxxxxxx	This restricts the display to user ids that match the specified pattern. For example, this command limits the display to user ids that begin with the letters "PROC": USER PROC*
WHAT xxxx	This restricts the display to users whose WHAT statistic matches the specified pattern. For example, this command limits the display to users with WHAT statistics that begin with the letters "EV", hence only EVAL users would be shown: WHAT EV*
ALL	ALL removes any restriction on the display. The display is returned to viewing all users.

All User Monitor screens give the option of 'ZOOMING' (the PF6 key) or obtaining a detail view (the PF10 key) on an individual user. The cursor must be on a valid 'user' line to determine the user for which ZOOM or DETAIL statistics are required.

ZOOM presents a non-scrollable (refer to Non-scrollable screen format) screen displaying the same statistics that were displayed on the original screen, but with screen lines representing time-sliced views of the selected user's performance.

DETAIL presents a display of most of the important statistics that can be displayed for any single user:

User Detail screen

The PF3 key from a ZOOM or DETAIL screen returns the user to the original User Monitor screen.
