We are running PRTG V220.127.116.112 and recently started using PRTG to monitor some of our Dell PowerEdge servers. We can add the Dell PowerEdge Heath Monitor and PRTG correctly raises an alarm when a hardware issue arises. Howerver when rebooting the OS, most of the time the Sensor goes in "No Such Instance SNMP error # 223". Deleting the sensor and recreating the sensor solves the problem. The problem can be also fixed by resetting the IDrac.
What can I do in PRTG to prevent the need to do one of the two workarounds ?
