6.5.1 Setting up an accounting system
The following is an overview of the steps you must take to set up an accounting
system. Refer to the commands and files noted in these steps for more specific
information.
1. Use the nulladm command to ensure that each file has the correct access
permission: read (r) and write (w) permission for the file owner and group, and
read(r) permission for others by typing:
# /usr/sbin/acct/nulladm wtmp pacct
This provides access to the pacct and wtmp files.
2. Update the /etc/acct/holidays file to include the hours you designate as prime
time and to reflect your holiday schedule for the year.
3. Turn on process accounting by adding the following line to the /etc/rc file or by
deleting the comment symbol (#) in front of the line if it exists:
/usr/bin/su - adm -c /usr/sbin/acct/startup
The startup procedure records the time that accounting was turned on and
cleans up the previous day’s accounting files.
4. Identify each file system you want included in disk accounting by adding the
following line to the stanza for the file system in the /etc/filesystems file:
account = true
5. Specify the data file to use for printer data by adding the following line to the
queue stanza in the /etc/qconfig file:
acctfile = /var/adm/qacct
6. As the adm user, create a /var/adm/acct/nite, a /var/adm/acct/fiscal, and a
/var/adm/acct/sum directory to collect daily and fiscal period records:
# su - adm
# cd /var/adm/acct
# mkdir nite fiscal sum
# exit
7. Set daily accounting procedures to run automatically by editing the
/var/spool/cron/crontabs/root file to include the dodisk, ckpacct, and runacct
commands.
8. Set the monthly accounting summary to run automatically by including the
monacct command in the /var/spool/cron/crontabs/root file. For example, type:
15 5 1 * * /usr/sbin/acct/monacct
Be sure to schedule this procedure early enough to finish the report. This
example starts the procedure at 5:15 a.m. on the first day of every month.
