1.2.6 Operations in a cluster system

When a cluster system is used, you can configure a highly reliable system that can continue to operate even when an error occurs in it. This allows you to operate and monitor Performance Management around the clock.

The figure below shows an example of operations when an error occurs at the monitored host in a cluster system.

Figure 1‒8: Example of cluster system operations

Two environments with identical settings are configured, and the host that normally runs is defined as the executing node, while the host that is used when an error occurs is defined as the standby node.

For details about Performance Management operations in a cluster system, see 3. Operations in a Cluster System.
