This device has a broken SNMP stack that doesn't return anything outside of its limited enterprise tree.

This device is set to the unix OS type, the one that works is set to messpc-ethernetbox, which has workarounds for the broken SNMP stack.

If you delete the device and re-add it, it should be added with the correct OS.

Subject: [Observium] Unable to poll a once working Device

Hi there,

I have multiple environmental Devices which are working fine for years now.

A view weeks ago one of was shown as unable to poll.

A SNMPwalk for the Device works fine.

I've tried to add the device via it's IP no luck there.

I've rebooted the Server and the Device multiple times. I flushed the DNS cache.

Attached are the debug Output of a poller run of a working Device poll_tempboxnl.txt and of the non-working Device poll_tempboxnz.txt as well as the discovery and snmpwalk output.

xxx_tempboxnl.txt working.

xxx_tempboxnz.txt not working.

Any suggestions are welcome.

Best regards

Andras
