We are trying to monitor some services on a Windows Failover Cluster, using the WMI Service sensor. The issues are that when PRTG is connecting to the cluster it connects to the node which has the cluster IP here and now, and it keeps the connection open. If the service is moved to another node in the cluster the PRTG WMI service sensor reports that the service is now down. It is correct that the service is no longer running a the first node, which is the one PRTG has a open connection to. But the service is still running on the cluster IP. Because Windows is moving both the service and the IP to the new node.
So how do we monitor this? How do we get PRTG to create a new connection to the new node? If we change the IPv4 Address/DNS Name settings on the PRTG device to/from IP or DNS name. PRTG create a new connection and show the service is running again. But we don't want to swap between IP/DNS name every time PRTG show that a service on a cluster is down.
Kind regards Jens
