Using prmanalyze to quickly identify resource

use

The prmanalyze utility scans accounting ﬁles for information on the

desired resource type (disk, memory, or CPU) and orders the accounting

records by the requested sort key (user, UNIX group, command name, or

PRMID).

This section focuses on the prmanalyze functionality that is relevant to

quickly identifying resource use. Command options are used, but not

described, in this section. For information on the command, see the

section “prmanalyze” on page 203.

NOTE The following examples are for illustrative purposes only. They are not

from an actual machine.

Step 1. Collect UNIX accounting data in a ﬁle (/var/adm/pacct by default) using

accton filename if you do not already have any accounting ﬁles. Ideally,

collect the accounting data over a period of one to seven days before

using prmanalyze.

Step 2. Use prmanalyze to create a summary CPU report, sorted by command

and piped to a reverse sort on the “% total” column:

# prmanalyze -s command -r cpu -p -t summary -1 filename | sort -r +5

summary CPU report by command name : 57203 records processed

The biggest CPU consumer is mrkt_rsch, a market research program.

Because this program helps determine priorities in product development,

it should be placed in a PRM group of its own. The second biggest

consumer is financials. This is another critical program. It must run to
