This subsection describes examples of definitions for disk monitoring.
Disk-related monitoring template alarms
Disk-related alarms in the monitoring template are stored in the alarm table for PFM UNIX Template Alarms [DSK] 09.00.
Table 3-14 Disk monitoring template alarms
Monitoring template alarms | Record | Field | Error threshold | Warning threshold | Description |
---|---|---|---|---|---|
I/O Wait Time | PI | Wait % | > 80 | > 60 | If the percentage of time during which the processor is waiting for I/O is greater than the threshold, I/O operations, such as updating a database, might be delayed. |
Disk Service Time | PI_DEVD | Avg Service Time | > 0.1 | > 0.06 | If the average operating time is greater than the threshold, the amount of information being input or output might be very large. |
File System Free(L) | PD_FSL | File System | <> dummy | <> dummy | If there is little unused area, disk space is insufficient. |
Mbytes Free | < 5120 | < 10240 | |||
File System Free(R) | PD_FSR | File System | <> dummy | <> dummy | If there is little unused area, disk space is insufficient. |
Mbytes Free | < 5120 | < 10240 | |||
Disk Busy % | PI_DEVD | Device Name | <> dummy | <> dummy | If the disk busy rate continues to be at or above the threshold, I/O operations might be concentrated on a specific disk. |
Busy % | >= 90 | >= 80 | |||
Disk Queue | PI_DEVD | Device Name | <> dummy | <> dummy | If the queue length continues to be at or above the threshold, the device is congested. |
Queue Length | >= 5 | >= 3 |
For details about the settings for the existing alarms, see 7. Monitoring Templates.
