act_cpu_time_top - Activity CPU time top monitor element

The high watermark for processor time used by activities at all nesting levels in a service class, workload, or work class. This value is reported in microseconds.

The monitor element returns -1 when COLLECT AGGREGATE ACTIVITY DATA for the service class or workload in which the activity runs is set to NONE. Activities contribute towards this high watermark only when request metrics are enabled. If activity metrics are not enabled, a value of 0 is returned.

For service classes, when you remap activities between service subclasses with a REMAP ACTIVITY action, only the act_cpu_time_top high watermark of the service subclass where an activity completes is updated, provided that a new high watermark is reached. The act_cpu_time_top high watermarks of other service subclasses an activity is mapped to but does not complete in are unaffected.
