1. Preamble

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" 4.1 kernel 2.0.27). 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.

2. Introduction

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.
