Monitoring processor use by utilities

You can run traces to collect data about the amount of processor time that is used by online utilities.

Procedure

Begin program-specific programming interface information.

To monitor processor use by utilities:

Run a trace that writes IFCID 0025 trace records.
For a list of trace classes that include IFCID 0025, see Performance trace.

The following types of information are collected:

  • Whether DFSORT or DB2SORT was invoked.
  • The number of parallel data or index sorts that were performed.
  • The amounts of time that a utility job used:
    • Total elapsed time
    • Total CPU time
    • Total zIIP time (if an accounting class 1 trace is also activated)
    • CPU time for sorts
    • zIIP time for sorts (if the sort program provided this value)
End program-specific programming interface information.
