Using HP-UX Workload Manager: A quick reference

How do I monitor HP-UX Workload Manager?

There are several methods for monitoring WLM, as described in the following sections.

ps [-P] [-R workload_group]

The ps command has options that are specific to PRM, which WLM uses to define workload groups

when dividing resources within a single HP-UX instance:

•-P

This option adds the column PRMID, showing the workload group for each process.

# ps -P

PRMID PID TTY TIME COMMAND

g3 6793 ttyp1 1:52 loop.pl

g3 6463 ttyp1 7:02 loop3.pl

g2 6462 ttyp1 4:34 loop2.pl

•-R workload_group

This option lists only the processes in the group named by workload_group. The following output

shows processes in the workload group g3:

# ps -R g3

PID TTY TIME COMMAND

6793 ttyp1 1:29 loop.pl

6463 ttyp1 6:41 loop3.pl

wlminfo

The wlminfo command, available in /opt/wlm/bin/, displays information about SLOs, metrics,

workload groups, virtual partitions or nPartitions, and the current host. The following example displays

group information:

# wlminfo group

Workload Group PRMID CPU Shares CPU Util Mem Shares Mem Util State

OTHERS 1 65.00 0.00 6.00 2.10 ON

g2 2 15.00 0.00 64.00 32.43 ON

g3 3 20.00 0.00 30.00 9.17 ON

The following example shows partition information:

% /opt/wlm/bin/wlminfo par
