Option 4 from the main menu presents a menu of file statistics screens. This menu is also accessible by entering =4 in the command line of any SirMon screen. In RKWeb, expanding the Performance > Files menu of the Monitor tab displays these statistics options in a sub-menu.

File Monitor menu

Selecting any of these numbered file statistics options presents a "scrollable screen" (see Scrollable screen format) of specific statistics for all open files in the Online system. The PF1 key displays definitions for the presented statistics:

Number Option Description
U Update the selection menu Allows SirMon administrators to customize the File Monitor menu.
A User AD-HOC An ad hoc view of file statistics specific to each SirMon user.
1 File Activity Display of disk activity, file enqueue counts, total page buffer utilization, and critical file resource conflicts.
2 Buffer Usage Detailed breakdown of each file's disk buffer usage by table together with disk read and write rates.
3 Critical File Resource Shows each category of resource conflict as a rate and the total number if users waiting on various critical file resources.
4 File Table Usage Shows file space utilization information for each open Model 204 file, broken down by table type.
5 Ordered Index Usage Information about ordered index data density and usage.

As many as 27 locally defined screens may also be accessed from the File Monitor menu. These screens are defined by a SirMon administrator as described in SirMon custom screens.

File Monitor commands

A number of special commands (TN3270 interface only) allow limiting the view of selected files:

FILE xxxxxxxx Restricts the display to files that match the pattern specified in xxxxxxxx. For example, this command limits the display of files to only those whose names begin with "GLB":

FILE GLB*

USER xxxx Restricts the display to files that are open by the user number specified. Wildcards are not allowed with this command.
SUBSYS xxxxxxxx Restricts the display to files that are open by the subsystem specified in xxxxxxxxxx. Wildcards are not allowed in subsystem specification.
ALL The command ALL removes any restrictions on the display. The display returns to showing all files.

Zoom and Detail views

All File Monitor screens give the option of zooming (the PF6 key) or obtaining a detail view (the PF10 key) on an individual file. The cursor must be positioned over a line of file statistics to determine the file for which Zoom or Detail statistics are required. In RKWeb, clicking a line of statistics opens a combined Zoom and Detail view.

  • Zoom presents a non-scrollable screen (refer to Non-scrollable screen format) with the same statistics as were presented on the original screen, but with screen lines representing time-sliced views of the selected file's performance.
  • Detail presents a display of most of the important statistics that can be displayed for any single file:

File Detail screen

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