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 into 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. No longer do you 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.
