6 Auditing and billing
WLM produces audit information when you activate a configuration
using the -t option with either the WLM daemon wlmd or the WLM
global arbiter daemon wlmpard:
# wlmd -t -a configfile
or
# wlmpard -t -a configfile
Once you’ve activated a configuration using -t, use the wlmaudit
command to display the audit data:
# wlmaudit
The wlmaudit command allows you to specify a date range for the data to
display. By default, the output is plain text; however, you can display
output in formatted HTML as well.
For command syntax, see the Appendix A, “WLM command reference,”
on page 363 or see wlmaudit(1M).
NOTE To ensure the smooth running of the operating system and key HP-UX
daemons, WLM runs these system processes in a special workload called
PRM_SYS. This group is not restrained by WLM: It consumes system
resources as needed. As a result, a workload’s CPU usage may be less
than its allocation (or entitlement as it is seen in the wlmaudit report)
because PRM_SYS requires some of the group’s resources. However, the
low usage could also be the result of the group’s low CPU resource
demands, or a combination of the two factors. Also, there may be times
when CPU usage is slightly above the allocation due to dynamics in the
CPU scheduler that WLM uses. Likewise, if memory management is
enabled, a workload’s memory usage may be less than the number of
memory shares for reasons similar to those just stated. It could also be
slightly above the memory shares value due to extreme paging pressure
or when the current group allocation is being reduced.
