Randomly today my VMware hardware status, host performance, and datastore sensors quick working. I get error PE002. There is a ping sensor for this device and it is working fine. We even rebooted the host and that did not help. The host is running VMware ESXi 6.0. I verified the machine that PRTG is installed on can ping the DNS name. I even tried to use the IP for the Device in PRTG. Nothing has changed on our VMware host recently. I am running PRTG version 188.8.131.529.
