This step removes a monitored system from the monitoring pool, all its Collector jobs as well as deletes all collected data including saved intervals. Before deletion you must stop all running Collector jobs linked to the monitored system.
To delete a system from the monitoring pool, go to the Collector jobs tab. Click Stop by all the Collector jobs for the system you are going to delete. Then select the system in system landscape and go to Edit > Delete system.
Warning in the case Collector jobs are not stopped before deletion
