Activating and Deactivating
Monitors
Inactive monitors have no history and do not pool data from the monitored resources automatically. These monitors can retrieve information only on demand. You can activate any deactivated monitor, but you cannot deactivate monitors that participate in the Java System Reports.
The deactivation of unused monitors minimizes the impact of the monitoring service on the CPU and memory consumption, and reduces the monitoring history by not storing the history for monitors that are rarely used.
You can also activate or deactivate more than one monitor from the monitoring tree at a time. The activation operations can be applied to both individual tree nodes and entire sub-trees.
You have opened the Monitor Browser.
