Section 1, Task 2: Start Your Data Collection software
Action 1: Start the logging and collector software, if it is not already running.

Start process accounting to a disk file with the accton command on each system you want to monitor. Though the exact syntax of the accton command varies slightly from one UNIX operating system to the other, it is generally the case that process accounting is initiated when root or another authorized userid issues the accton command. As processes end, information on the resources they consumed is logged by the operating system. See the man file for the UNIX system in question for details on running the accton command.

Refer to the Collector - Specific Appendix Enhanced UNIX Accounting Support User Guide for more information.
