Description
Hello!
I could really use some help. We noticed most of our graphs had disappeared. Unfortunately, exactly what went on to break this is a mystery for now and I'm trying to unravel the issue and fix it.
While manually running a discovery on all devices, I saw this error in the mibs module output for every single device:
Empty oids passed to snmp_command(). THIS SHOULD NOT HAPPEN. PLEASE REPORT TO DEVELOPERS.
The system hosting Observium can snmpwalk any of our devices as normal, but the "mibs" module in Observium is unable to do the walks needed during a run of discovery.php. The result is all of our traffic graphs for all devices have basically disappeared and I just can't see why calls to the snmp_command() function is failing.
All the usual mibs are in the /opt/observium/mibs directory and permissions are all readable.
I've run out of ideas and need help on where to look next. Any clues would be super appreciated! If any other information is needed to figure this out, please let me know and I'll post.
Thanks!
Example of an snmpwalk working just fine outside Observium on one of our faithful old switches:
[root@nms observium]# snmpwalk -v1 -c redacted switch01 sysDescr

An example of one specific device running against only the mibs module, for output brevity's sake:
[root@nms observium]# /opt/observium/discovery.php -h 80 -m mibs
