4.36 PhysicalDiskIO

Use this Knowledge Script to monitor the physical disk I/O activity in kilobytes per second. The Knowledge Script monitors the size of physical disk reads and physical disk writes per second.

On Solaris, Linux, and AIX AppManager raises an event if the size of disk reads per second, the size of disk writes per second, or the overall throughput per second exceeds the threshold you set.

On HP-UX, this Knowledge Script only monitors overall throughput and raises an event if the total size of reads and writes per second is over the threshold.

NOTE:Oracle Solaris ZFS and ZFS Storage Pools file system monitoring is not available for this Knowledge Script.

Set the following parameters as needed:

Description

How to Set It

General Settings

Event? (y/n)

Select Yes to raise events. The default is Yes.

Event severity level

Set the event severity level, from 1 to 40, to indicate the importance of the event. The default is 8.

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.

Threshold settings Collection

Maximum reads per second (KB) threshold

Specify the threshold for the maximum rate of read operations in KB per second. The default is 50 KB per second.

Maximum writes per second (KB) threshold

Specify the threshold for the maximum rate of write operations in KB per second. The default is 50 KB per second.

Maximum throughput per second (KB) threshold

Specify the threshold for the maximum rate of read and write operations in KB per second. The default is 100 KB per second.

Maximum reads per second threshold

Specify the threshold for the maximum number of read operations per second. The default is 50 operations per second.

NOTE:This parameter is not supported on Solaris 11 or later versions.

Maximum writes per second threshold

Specify the threshold for the maximum number of write operations per second. The default is 50 operations per second.

NOTE:This parameter is not supported on Solaris 11 or later versions.

Maximum throughput per second threshold

Specify the threshold for the maximum number of read and write operations per second. The default is 100 operations per second.

NOTE:This parameter is not supported on Solaris 11 or later versions.

Data Collection

Collect data for reads per second (KB)?

Select Yes to collect data for charts and reports. If set to Yes, the script returns the rate of disk read operations in KB per second for each disk. The default is unselected.

Collect data for writes per second (KB)?

Select Yes to collect data for charts and reports. If set to Yes, the script returns the rate of disk write operations in KB per second for each disk. The default is unselected.

Collect data for throughput per second(KB)?

Set to Yes to collect data for charts and reports. If set to Yes, the script returns the rate of disk read and write operations in KB per second for each disk. The default is unselected.

Collect data for reads per second?

Set to Yes to collect data for charts and reports. If set to Yes, the script returns the number of disk read operations per second for each disk. The default is unselected.

NOTE:This parameter is not supported on Solaris 11 or later versions.

Collect data for writes per second?

Set to Yes to collect data for charts and reports. If set to Yes, the script returns the number of disk write operations per second for each disk. The default is unselected.

NOTE:This parameter is not supported on Solaris 11 or later versions.

Collect data for throughput per second?

Set to Yes to collect data for charts and reports. If set to Yes, the script returns the number of disk read and write operations per second for each disk. The default is unselected.

NOTE:This parameter is not supported on Solaris 11 or later versions.

Enable debugging? (y/n)

Select Yes to enable debugging. The default is unselected.
