SNMP Error 222



Hey there!

I need somehelp with snmp monitoring for a Sophos SG Firewall. There is a MIB-file, but i cannot import them in our PRTG Monitoring Core Server with the converter tool. i tried to get a solution with the specific OID of the notification, but then the 222 Error appears.

CPU and RAM sensors are working fine, so there isn't a problem with the community string or something. I use SNMPv2c at the moment. Any ideas?

Thanks for some inspiration.

Please use our SNMP Tester (https://www.paessler.com/tools/snmptester), run it on the PRTG Host (or host of the Remote Probe), and perform a scan with the imported OIDLib against the target device. Which results do you get in the Tester? Please send us the result logfile from the Tester.

best regards

This may help you and others with Sophos firewalls, but we had to set the PRTG snmp version to V1. No matter what the Sophos version is, as long as the PRTG server is authorized to the Sophos, then set PRTG to V1. PRTG set to V2c and V3 seemed to balk and give no sensors. After changing to V1, everything lit up.
