Daily Command Summary
The Daily Command Summary report shows the system resource use by command.
With this report, you can identify the most heavily used commands and, based
on how those commands use system resources, gain insight on how best to tune
the system.
These reports are sorted by TOTAL KCOREMIN, which is an arbitrary gauge but often a good one for calculating
drain on a system.
A sample daily command summary follows.

The following table describes the data provided in the Daily Command
Summary.
Table 20-5 Daily Command Summary
Column | Description |
|---|
COMMAND NAME | Name of the command.
Unfortunately, all shell procedures are lumped together under the name sh because only object modules are reported by the process accounting
system. You should monitor the frequency of programs called a.out or core or any other unexpected name. You
can use the acctcom program to determine who executed an
oddly named command and if superuser privileges were used. |
NUMBER CMDS | Total number of times
this command was run during prime time. |
TOTAL KCOREMIN
| Total cumulative measurement
of the Kbyte segments of memory used by a process per minute of run time. |
TOTAL CPU-MIN
| Total processing time
this program accumulated during prime time. |
TOTAL REAL-MIN | Total real-time (wall-clock)
minutes this program accumulated. |
MEAN SIZE-K | Mean of the TOTAL KCOREMIN over the number of invocations
reflected by NUMBER CMDS. |
MEAN CPU-MIN | Mean derived between the NUMBER CMDS and TOTAL CPU-MIN. |
HOG FACTOR | Total CPU time divided
by elapsed time. Shows the ratio of system availability to system use, providing
a relative measure of total available CPU time consumed by the process during
its execution. |
CHARS TRNSFD | Total number of characters
pushed around by the read and write system calls. Might be negative due to
overflow. |
BLOCKS READ | Total number of the physical block
reads and writes that a process performed. |
Monthly Command Summary
The format of the Daily Command Summary and the Monthly Command Summary
reports are virtually the same. However, the daily summary reports only on
the current accounting period while the monthly summary reports on the start
of the fiscal period to the current date. In other words, the monthly report
is a cumulative summary that reflects the data accumulated since the last
invocation of the monacct program.
A sample report follows.

This report gives the date when a particular login was last used. You
can use this information to find unused logins and login directories that
can be archived and deleted. A sample report appears follows.

Looking at the pacct File With acctcom
At any time, you can examine the contents of the /var/adm/pacctn files, or any file with records in
the acct.h format, by using the acctcom
program. If you do not specify any files and do not provide any standard input
when you run this command, the acctcom command reads the pacct file. Each record read by the acctcom
command represents information about a terminated process. Active processes
can be examined by running the ps command. The default
output of the acctcom command provides the following information:
Sample acctcom output follows:
# acctcom
