Is there a way to automatically restart the probes when status is unknown?



I'm running PRTG Network Monitor and some times my sensors status go to unknown. When this happens my monitoring stops. Is there a way to correct this? It didn't happen on older versions.

Does this affect mainly WMI sensors? If so, please update to the latest release, version and see if this reduces the issue.

This happens with all sensors, SNMP, WMI and even pings. I updated to and will see what happens.

I have the same problem, but only with WMI sensors. I'm already running version Anything else I can try?

The status can be unkown for a couple of hours suddenly they are up.
