Monitoring your system

This chapter provides a high-level introduction to the concepts of monitoring. Because the monitoring application is provided by the RSCT product, detailed information about planning for monitoring your system, tracking system events, and using and modifying the predefined scripts, expressions, commands, and responses is provided with the RSCT publications (refer to the IBM RSCT for Linux: Guide and Reference).

The RSCT Monitoring application offers a comprehensive set of monitoring and response capabilities that lets you detect, and in many cases correct, system resource problems such as a critical file system becoming full. You can monitor virtually all aspects of your system resources and specify a wide range of actions to be taken when a problem occurs, from simple notification by e-mail to recovery that runs a user-written script. You can specify an unlimited number of actions to be taken in response to an event.

As system administrator, you have a great deal of flexibility in responding to events. You can respond to an event in different ways based on the day of the week and time of day. The following are some examples of how you can use monitoring:

CSM uses RMC to monitor the system and to perform many of its operations. For more information about RMC, see IBM RSCT for Linux: Guide and Reference. For information about the command line interface to the RMC subsystem, see IBM RSCT for Linux: Technical Reference.
