3.3 Monitoring and Comparing Performance Status by Host

The dashboard allows you to monitor the entire system, as well as monitor specific departments of some of the systems.

For example, if your Web Reservation Services division has about four hosts for Web, you can create and monitor the following dashboards: By specializing in departments, you can reduce the granularity of monitored objects. In addition to the Node Status Monitor panel and the Alert Info panel, you can also monitor metric that you want to monitor specifically.
