Problem setting Sensor to Error in a v8.1Clustered environment



Before migrating to a clustered PRTG setup we were able to log into a PRTG Node and set a sensor to error for testing purposes (this is part of our monthly test to ensure that our sensor notifications are being sent/received). Now, when setting a sensor to error (Right click -> Pause -> Set Sensor to Error) it must be completed on the Primary Node in the cluster (and cannot be completed on the secondary node as configuration changes are not accepted). This causes the sensor to go into a Partial Down state (Primary Node recognises it has been set to error, but secondary node does not because we cannot set it in that node) and the notification is never triggered because a Down (Full Down) state is never met.

Is there a way to set a sensor to error on both nodes to initiate a down state?
