 Deactivating and Reactivating Monitoring Tree Elements


You can deactivate individual monitoring tree elements (MTEs). This means that the system collects no values and generates no alerts for these MTEs. This is useful if, for example, you are working on a particular component on which an error occurred. You can avoid the system generating additional alerts for this component while you are working on the problem. As the data collection methods for the deactivated MTEs are also no longer executed, you also reduce the workload created by monitoring.

You can also Delete nodes. Deleted nodes are no longer displayed in the alert monitoring tree, are explicitly deleted in shared memory, and can only be recreated by restarting the relevant application server or associated startup method (see Deleting and Recreating Nodes in the Alert Monitoring Tree).


To be able to change the Alert Monitor, you must first activate the maintenance functions.


You cannot deactivate virtual nodes.


  1. Choose CCMS → Control/Monitoring → Alert Monitor, or call transaction RZ20.
  2. Expand the monitor set that contains the monitors that you require and choose Start Monitor.
  3. Choose Extras → Activate Maintenance Function.
  4. Select the desired node in the Alert Monitor, and choose Edit → Node (MTE) → Deactivate.
  5. The node now contains the description <<<<Node is deactivated>>>>. If you also no longer want to display the node, you must change the appropriate monitor definition (see Creating and Changing Monitors). This is, however, only possible for your own monitors, as you cannot change the monitors delivered by SAP.


The MTE still exists in the monitoring segment of the shared memory, but is no longer used. As the data collection methods are also no longer performed for this MTE, this does not affect performance.

The deactivation of the data collection method applies only to the selected MTEs. If the same method is still assigned to other MTEs, the deactivation of a method for one node does not affect other nodes with the same method.

No alerts are generated in the selected MTEs until you reactivate them. To do this, repeat the procedure above, but choose Edit → Node (MTE) → Activate.
