The psacct
package implements the process
accounting service in addition to the following utilities that you
can use to monitor process activities:
- ac
Displays connection times in hours for a user as recorded in the
wtmp
file (by default,/var/log/wtmp
).- accton
Turns on process accounting to the specified file. If you do not specify a file name argument, process accounting is stopped. The default system accounting file is
/var/account/pacct
.- lastcomm
Displays information about previously executed commands as recorded in the system accounting file.
- sa
Summarizes information about previously executed commands as recorded in the system accounting file.
As for any logging activity, ensure that the file system has
enough space to store the system accounting and
wtmp
files. Monitor the size of the files
and, if necessary, truncate them.
For more information, see the ac(1)

accton(8)
