Monitoring template alarmsRecordFieldError thresholdWarning thresholdDescription
I/O Wait TimePIWait %> 80> 60If 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 TimePI_DEVDAvg Service Time> 0.1> 0.06If 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_FSLFile System<> dummy<> dummyIf there is little unused area, disk space is insufficient.

Mbytes Free< 5120< 10240
Disk Busy %PI_DEVDDevice Name<> dummy<> dummyIf the disk busy rate continues to be at or above the threshold, I/O operations might be concentrated on a specific disk.
