Hardware Monitoring Overview
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.
