Workload management tier report
To print the tier report, specify the -T flag.
This report contains all the columns detailed in the common summary metrics as well as its own defined here:
- Tier
- Indicates the tier number
- Superclass
- The optional column heading indicates the superclass name when tier applies to a superclass (when the -a flag is used).
The -O subclass=on option can be added to display the list of subclasses. The -a <supclassname> option allows reporting only the details of a given super class.
Examples:
- To display memory statistics about all WLM tiers and superclasses
in the system, enter:

Each Tier has a summary header with the Inuse, Pin, Paging space, and Virtual memory, and then the list of all its classes.

and classes in the system, enter:

- To display memory statistics about a particular WLM superclass
in a tier, with segment and per page size details, enter:

The distribution between the different page sizes is displayed by the -O pgsz=on option. Then, as -O segment=on is specified, the subclass statistics are followed by its segments statistics. Finally, as -O pidlist=on' is specified for each segment, the list of process which uses it, is displayed.
