Option 5 from the TN3270 SirMon main menu presents a menu of subsystem statistics screens. This menu is also accessible by entering =5 in the command line of any SirMon screen. In RKWeb, expanding the Performance > Subsystems menu of the Monitor tab displays these statistics options in a sub-menu.

Subsystem Monitor menu


Selecting any option from the subsystem statistics menu brings you to a scrollable screen displaying specific statistics for all defined or active subsystems in an Online system. The PF1 key displays explanatory text for the given statistics.

Number Option Description
U Update the selection menu Allows SirMon administrators to customize the Subsystem Monitor menu.
A User AD-HOC An adhoc view of subsystem statistics specific to each SirMon user.
1 Active/Inactive Subsystems Display of status, number of users, access (PRIVATE, PUBLIC, SEMIPUBLIC), non-precompiled prefix and precompiled prefix for all subsystems defined in the Online.

This is the only Subsystem Monitor screen from which subsystems may be STARTed or STOPped.

2 Resident QTBL Usage Detailed breakdown of key information about each subsystem's use of resident QTBL.

As many as 30 locally defined screens may also be accessed from the Subsystem Monitor menu. These screens are defined by a SirMon administrator as described in SirMon custom screens.

Subsystem Monitor commands

The displayed list of subsystems can be limited with the following commands.

FILE xxxxxxxx Limits the display to subsystems that have the specified file open. Wildcards are not allowed in the file specification.
SUBSYS xxxxxxxx Limits the display to subsystem names that match the specified wildcard string. For example, SUBSYS SIR* limits the display to only those subsystems that begin with the letters "SIR".
ALL Removes any restrictions on the subsystem display. All subsystems are presented.

Zoom and Detail views

All Subsystem Monitor screens give the option of zooming (the PF6 key) or obtaining a detail view (the PF10 key) on an individual subsystem. To determine the subsystem for which Zoom or Detail statistics are required, the cursor must be on a valid "subsystem" line.

  • Zoom presents a non-scrollable screen of the same statistics as were presented on the original screen, but screen lines represent time-sliced views of the selected subsystem's performance.
  • Detail presents a display of most of the important statistics and information that can be displayed for any single subsystem:

Subsystem Detail screen


The PF3 key from a Zoom or Detail screen returns the original Subsystem Monitor screen.
