This is a tracking issue for an enhancement that should be included in OpenNMS 2.0
The manage/unmanage interface panel in the GUI is kludgy. Currently one must uncheck a particular box next to a service or and interface, and then force a rescan for the behaviour to take effect. Depending on whether or not capsd is being used or whether or not the service is provisiond this can take some time and have uncertain results.
An admin user should be able to check or uncheck a particular service and then apply it immediately. We should also log the name of the user and the time they performed the action.
Note that this is exception management. If a service isn't in a poller package, it won't be polled even if managed.
