Use this Knowledge Script to monitor physical disk activity and average response time. A disk is considered busy if the percentage of time the disk is in operation is high or the average response time is over the threshold. With this Knowledge Script, you can monitor the load for individual disks or the overall load across all physical disks in a computer.
Total disk activity and average response time threshold are reported separately. Each detailed message will contain both values and the value exceeding the threshold will be mentioned.
NOTE:If the total disk activity or average response time threshold is exceeded, the disk is considered overloaded and AppManager raises an event.
Physical disk folder or individual physical disks.
The default interval for this script is Every 10 minutes.
Set the following parameters as needed:

Description |
How to Set It |
|---|---|
|
Collect data for physical disk busy? (y/n) |
Set to y to collect data for charts and reports. If set to y, the script returns the percentage of time the disk is busy and the average response time for requests. The default is n. |
|
Collect data for average response time? (y/n) (unavailable on AIX) |
Set to y to collect data for charts and reports. If set to y, the script returns the average response time for requests. The default is n |
|
Event if disk activity and response time over threshold? (y/n) |
Set to y to raise events when both the disk activity and average response are over their respective thresholds. The default is y. |
|
Average response time maximum threshold (unavailable on AIX) |
Specify a threshold for the maximum response time in milliseconds. The default is 200 milliseconds. Do not use this parameter on computers running an AIX operating system. |
|
Maximum physical disk activity (% busy) threshold |
Specify a threshold for the maximum percentage of disk activity before raising an event. The default is 80% busy. |
|
Monitor overall physical disk load? (y/n) |
Set to y to monitor the overall disk load (for all physical disks on a system). Set to n to monitor individual disks separately. The default is n. |
|
Event severity level |
Specify the event severity level, from 0 to 40, to indicate the importance of the event. The default is 5. |
|
Event severity for internal failure |
Set the event severity level, from 1 to 40, to indicate the importance of an event in which this job experienced an internal error. The default is 5. |
|
Enable debugging? (y/n) |
Set to y to enable debugging. The default is n. |
