Setting Up System Accounting

You can set up system accounting to run while the system is in multiuser mode (system state 2). Generally, this task involves:

  1. Creating the /etc/rc0.d/K22acct and /etc/rc2.d/S22acct startup scripts

  2. Modifying the /var/spool/cron/crontabs/adm and /var/spool/cron/crontabs/root crontab files

The following table describes the default accounting scripts.

Table 19–2 Default Accounting Scripts

Accounting Script 

Man Page 

Purpose 

Run Frequency 

ckpacct

ckpacct(1M)

Checks the size of the /usr/adm/pacct log file and makes sure it does not get too large.

Periodically 

runacct

runacct(1M)

Processes connect, disk, and fee accounting information. You can remove the commands from this script for the accounting features you do not want processed. 

Daily 

monacct

monacct(1M)

Generates fiscal accounting summary reports on a monthly basis. You can determine how often this script is run. You can remove the commands from this script for the accounting features you do not want generated. 

On a fiscal basis 

You can choose which accounting scripts run by default. After these entries have been added to the crontab files, accounting should run automatically.

How to Set Up System Accounting

  1. Become superuser.

  2. If necessary, install the SUNWaccr and SUNWaccu packages on your system by using the pkgadd command.

  3. Install /etc/init.d/acct as the startup script for Run Level 2. 


    # ln /etc/init.d/acct /etc/rc2.d/S22acct

  4. Install /etc/init.d/acct as the stop script for Run Level 0.


    # ln /etc/init.d/acct /etc/rc0.d/K22acct

  5. Add the following lines to the adm crontab file to start the ckpacct, runacct, and monacct scripts automatically.


    # EDITOR=vi; export EDITOR
# crontab -e adm
0 * * * * /usr/lib/acct/ckpacct
30 2 * * * /usr/lib/acct/runacct 2> /var/adm/acct/nite/fd2log
30 7 1 * * /usr/lib/acct/monacct

  6. Add the following line to the root crontab file to start the dodisk script automatically.


    # crontab -e
30 22 * * 4 /usr/lib/acct/dodisk

  7. Edit /etc/acct/holidays to include national and local holidays.

    For more information, see holidays(4) and the example that follows.

  8. Reboot the system, or start accounting manually by typing: 


    # /etc/init.d/acct start

Examples—Setting Up Accounting

This modified adm crontab contains entries for the ckpacct, runacct, and monacct scripts. 


#ident  "@(#)adm        1.5     92/07/14 SMI"    /* SVr4.0 1.2   */
#
# The adm crontab file should contain startup of performance 
# collection if the profiling and performance feature has been 
# installed.
0 * * * * /usr/lib/acct/ckpacct
30 2 * * * /usr/lib/acct/runacct 2> /var/adm/acct/nite/fd2log
30 7 1 * * /usr/lib/acct/monacct

This modified root crontab contains entries for the dodisk program. 


#ident  "@(#)root       1.19    98/07/06 SMI"   /* SVr4.0 1.1.3.1       */
#
# The root crontab should be used to perform accounting data collection.
#
# The rtc command is run to adjust the real time clock if and when
# daylight savings time changes.
#
10 3 * * * /usr/sbin/logadm
15 3 * * 0 /usr/lib/fs/nfs/nfsfind
1 2 * * * [ -x /usr/sbin/rtc ] && /usr/sbin/rtc -c > /dev/null 2>&1
30 3 * * * [ -x /usr/lib/gss/gsscred_clean ] && /usr/lib/gss/gsscred_clean
30 22 * * 4 /usr/lib/acct/dodisk
