This subsection describes examples of definitions for memory monitoring.
Memory-related monitoring template alarms
Memory-related alarms in the monitoring template are stored in the alarm table for PFM UNIX Template Alarms [MEM] 09.00.
Table 3-10 Memory monitoring template alarms
Monitoring template alarm | Record | Field | Error threshold | Warning threshold | Description |
---|---|---|---|---|---|
Pagescans | PI | Page Scans/sec | > 150 | > 100 | If the number of page scans that occurred is greater than the threshold, memory might be insufficient. |
Swap Outs | PI | Swapped-Out Pages/sec | > 200 | > 100 | If the number of pages is greater than the threshold, memory might be insufficient. |
Alloc Mem Mbytes | PI | Alloc Swap Mbytes | >= 1800 | >= 1024 | If the amount of used memory continues to be at or above the threshold (the Total Physical Mem Mbytes field value of the PI record), physical memory might be insufficient. |
For details about the settings for the existing alarms, see 7. Monitoring Templates.
Memory-related monitoring template reports
Table 3-11 Memory monitoring template reports
Report name | Displayed information |
