I have a rather starnge issue with one of my physical servers and PRTG. In PRTG, I'm getting SNMP error #2, but the sensors were working fine a couple of days ago.
There has been no change to either PRTG og the server it self. Does anyone have any idea how I can get rid of this error, so the sensors can show normal again?
- stop/start sensors
- Pause/unpause sensors
- stop/start IBM Director services + SNMP service
- Reconfigured the SNMP service
- Rebooted the server
- Tried re-adding the sensors (I can't, because PRTG reports error #2)
Check this screenshot. Please notice that 4 of my hardware sensors are working, but only sensors associated with DISK are not working.
