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 |
