Usage

This element can be used to help determine whether or not the UOWTOTALTIME threshold is effective and can also help to determine how to configure such a threshold.

For service classes, this monitor element returns -1 when COLLECT AGGREGATE ACTIVITY DATA for the service class is set to NONE.

For workloads, this monitor element returns -1 if COLLECT AGGREGATE ACTIVITY DATA for the workload is set to NONE.

For a service class, measurements taken for this high watermark are computed for the service class assigned by the workload. Any mapping by a work action set to change the service class of an activity does not affect this high watermark.
