What is Hardware Monitoring?

Hardware monitoring is the process of watching a hardware resource (such as a disk) for the occurrence of any unusual activity, called an event. When an event occurs, it is reported using a variety of notification methods (such as email). Event detection and notification are all handled automatically with minimal involvement on your part.

To achieve a high level of system reliability and availability, it is essential that you know when any system resource is experiencing a problem. Hardware monitoring gives you the ability to detect problems with your system hardware resources. By providing immediate detection and notification, hardware monitoring allows you to quickly identify and correct problems—often before they impact system operation.

Another important feature of hardware monitoring is its integration with applications responsible for maintaining system availability, such as MC/ServiceGuard. It is vital that these applications be alerted to hardware problems immediately so they can take the necessary action to avoid system interruption. Hardware monitoring is easily integrated with MC/ServiceGuard, and the necessary notification methods are provided for communication with other applications such as HP OpenView.

Hardware monitoring is designed to provide a high level of protection against system hardware failure with minimal impact on system performance. By using hardware monitoring, you can virtually eliminate undetected hardware failures that could interrupt system operation or cause data loss.
