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.
Selecting any option from this menu transfers the user into a "scrollable screen"
(see Scrollable screen format) displaying specific statistics for all
open files in an Online system.
The PF1 key displays definitions for the presented statistics.
File Monitor menu
| 4.U Update the selection menu | Allows SirMon administrators to customize the File Monitor menu. |
|---|---|
| 4.A User AD-HOC | An adhoc view of file statistics specific to each SirMon user. |
| 4.1 File Activity | Display of disk activity, file enqueue counts, total page buffer utilization, and critical file resource conflicts. |
| 4.2 Buffer Usage | Detailed breakdown of each file's disk buffer usage by table together with disk read and write rates. |
| 4.3 Critical File Resource | Shows each category of resource conflict as a rate and the total number if users waiting on various critical file resources. |
| 4.4 File Table Usage | Shows file space utilization information for each open Model 204 file, broken down by table type. |
| 4.5 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.
A number of special commands 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. |
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.
- 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.
