If you no longer want to monitor a remote system, you can remove it from the Enterprise View. Removing a remote system does not take it off-line.
To remove a remote system:
In the menu bar, select Remote, select Remove managed system, then click the system you want to remove.
The Remove Managed System window opens.
If you want to continue receiving events from the remote system after it has been removed from the local system, select Continue to receive events from the remote system from the drop-down menu.
Click OK.
