Hardware Monitoring Overview

Beneﬁts of Hardware Monitoring

Hardware monitoring provides the following beneﬁts:

•Reduces system downtime by detecting hardware failures when they occur, allowing you to quickly identify and correct problems.

•Integrates with MC/ServiceGuard and other applications responsible for maintaining system availability. These applications can now add many hardware resources to the components they monitor.

•Minimizes the time required to isolate and repair failures through detailed messages describing what the problem is and how to ﬁx it.

•Includes a default monitoring conﬁguration that offers immediate protection for your system hardware without any intervention on your part after monitoring is enabled.

•Provides a common tool for monitoring a wide variety of system hardware resources.

•Offers a variety of notiﬁcation methods to alert you when a problem occurs. You no longer need to check the system console to determine if something has gone wrong.

•Requires minimal maintenance once installed and conﬁgured. New hardware resources added to the system are automatically included in the monitoring structure.
