So out of the blue, our sensors are reporting false values. WMI Disk Space sensors are reporting 0% free space, pings are timing out, WMI service sensors are reporting services to not be running, it's just chaos. I have tried increased the scanning intervals and doubled the amount of probes. I have also gone through the logs and find nothing out of the ordinary. To PRTG, the sensors are functioning just fine because they are returning values but those values are relative zeros. There are about 100 failing sensors with little or no relation to each other.
No changes have been made to PRTG or the host machines. All the hosts are physicals and don't get any automatic updates. I want to go as far to say our setup has not changed in any way.
We are running version 13.1.2.1463.
What can cause this?
