-!!!2. Introduction
-
-This document describes how to enable system process accounting on
-a Linux host and the usage of various process accounting commands. It is
-intended for users running kernel versions greater than or equal to 1.3.73
-(tested on !RedHat(tm) 4.1 kernel 2..27). Kernels older than 1.3.73 may
-need a patch in order to use the process accounting feature.
-
-
-
-Feel free to send any feedback or comments to bertie@scn.org
-if you find an error, or if any information is missing. I appreciate it.
-

-!!!3. What is process accounting?
-
-Process accounting is the method of recording and summarizing
-commands executed on Linux. The modern Linux kernel is capable of keeping
-process accounting records for the commands being run, the user who executed
-the command, the CPU time, and much more.
-
-
-
-Process accounting enables you to keep detailed accounting
-information for the system resources used, their allocation among users, and
-system monitoring.
-
-----
-!!!4. Current Status of Process Accounting under Linux
-
-Process accounting support has been integrated into the newer
-kernels (version b= 1.3.73). If you are running an older kernel, you may
-need some patch files. The patches are available from
-ftp://iguana.hut.fi/pub/linux/Kernel/process_accounting
-
-
-----
-!!!5. Requirements for Process Accounting on Linux
-!!5.1. Kernel
-
-A Linux kernel version greater than or equal to version 1.3.73 is required, and I
-recommended 2.x. The kernel source is available from
-http://sunsite.unc.edu/pub/Linux/kernel/v2.
-
-
-----
-!!5.2. Process Accounting Software
-
-Depending on the Linux distribution you have, you may
-not have the process accounting software package installed on your system. If
-you don't have it, try downloading the package from
-http://sunsite.unc.edu/pub/Linux/system/admin/quota-acct-modified.tgz
-
-
-----
-!!!6. Process Accounting Setup on Linux
-
-
-
-
-#
-
-Compile and install process accounting software.
-
-
-
-The process accounting software package is available from
-http://sunsite.unc.edu/pub/Linux/system/admin/quota-acct-modified.tgz
-
-
-
-#
-#
-
-Modify your system init script and turn on process accounting
-at boot time.
-
-
-
-Here's an example:
-
-
-# Turn process accounting on.
-if
[[ -x /sbin/accton
]
-then
-/sbin/accton /var/log/pacct
-echo "Process accounting turned on."
-fi
-
-#
-#
-
-Create accounting record file "pacct."
-
-
-
-Your process accounting software will print out all commands
-executed to the file /var/log/pacct by default.
-
-
-
-To create the accounting record file:
-
-touch /var/log/pacct
-
-
-
-This record file should be owned by root, and it has read-write
-permission for root and read permission for anybody else:
-
-
-chown root /var/log/pacct
-chmod 0644 /var/log/pacct
-#
-#
-
-Reboot.
-
-
-
-Now reboot your system for changes you made to take effect.
-
-
-
-#----
-!!!7. Miscellaneous Process Accounting Commands
-
-
-
-; __ac__:
-
-__ac__ prints out statistics about users' connection times in
-hours based on the logins and logouts in the current /var/log/wtmp file. __ac__ is
-also capable of printing out time totals for each day (-d option), and for each
-user (-p option).
-
-; __accton__:
-
-__accton__ is used to turn on or turn off process accounting.
-The file is normally executed at system bootup or shutdown via system init
-scripts.
-
-; __last__:
-
-__last__ goes through the /var/log/wtmp file and prints out
-information about users' connection times.
-
-; __sa__:
-
-__sa__ summarizes accounting information from previously
-executed commands, software I/O operation times, and CPU times, as recorded in the
-accounting record file /var/account/pacct.
-
-; __lastcomm__:
-
-__lastcomm__ prints out the information about all previously
-executed commands, recorded in /var/account/pacct
