CQD
The CPU Queue Depth (CQD) sampler monitors the CPU active task queue and produces a warning message when the average queue depth of tasks that are ready to run and waiting for a processor exceeds a threshold you specify.
Syntax
The parameters are defined as follows:
Parameter | Description |
|---|---|
int | is the length of the sample period in intervals; the default sample period is 30 seconds (one interval) |
depth | is the threshold number of tasks that are ready to execute and waiting for a processor |
Example
Assuming a report interval of 30 seconds, the following control statement displays warning messages at 30-second intervals if the average CPU queue depth exceeds 10:
CQD 1,10
Warning message
The following warning message is issued by the CQD sampler:
PWSCQD01 *WARNING* CPU QUEUE DEPTH IS xxx
Message PWSCQD01 indicates that xxx is the average number of tasks that are waiting for a processor.
