Fine-tuning your PRM conﬁguration

Using GlancePlus to analyze your conﬁguration

Using GlancePlus to analyze your

conﬁguration

The following steps guide you in using GlancePlus to determine

adjustments you may wish to make to your conﬁguration. GlancePlus

has both a text interface (glance) and an X-Windows interface (gpm).

Having PRM conﬁgured but not enabled allows you to track resource use

by PRM group through GlancePlus without having PRM actually control

the use of these resources. GlancePlus allows you to monitor CPU,

memory, and disk bandwidth resource usage.

NOTE GlancePlus does not correctly track the PRM ID at the process level for

HP-UX 11i v1 and later in versions C.02.65.00 through C.03.25.00. For

correct metrics reporting for FSS PRM groups, use GlancePlus Version

C.03.35.00.

Also, GlancePlus returns incorrect data for the PRM_SYS group for PRM

conﬁgurations with processor sets deﬁned. Use the prmmonitor

command instead of GlancePlus if you are using PSET PRM groups.

Step 1. Load the PRM conﬁguration you want to analyze with

prmconfig -ie APPL if it is not already loaded. This allows you to view

the PRM Group List under the Reports menu in GlancePlus.

Step 2. Compare the PRM resource shares against the reported usage in

GlancePlus during peak activity. Select the PRM Group List under the

Reports menu to see the active processes, users, and their resource use.

Determine if you need to adjust the shares or move users or processes to

different groups.

Step 3. Change your PRM conﬁguration based on your review of the GlancePlus

data.

Step 4. Load the changed PRM conﬁguration with prmconfig -ie APPL. This

load places processes in the owners’ initial groups and each conﬁgured

application in its assigned group.

Step 5. Repeat Step 2, Step 3, and Step 4 as needed.
