Spine and MIB Path Problem

[reub]

I've got an existing Cacti setup which works fairly well using cmd.php to do the polling, and thought I'd attempt to cut this across to using spine - for faster performance. I have successfully compiled 0.8.8b from Gentoo portage and configured my spine.conf as per the documentation.

However many of the polling runs are now generating the following message:

12/24/2014 10:50:31 AM - SPINE: Poller[0] Host[32] ERROR: Problems parsing Multi SNMP OID! (oid: PowerNet-MIB::upsAdvInputLineVoltage.0), Set MAX_OIDS to 1 for this host to isolate bad OID

I already had the MAX-OIDs for this and many other hosts host set to 1 - so this message is actually incorrect and misleading.

However running spine with debugging enabled shows the real reason for the problem:

spine is unable to load the MIB and therefore all of the textual defined SNMP queries are failing.

I have a whole lot of MIBs in /etc/snmp and directories under that. These are defined and work correctly in my snmp.conf file for net-snmp. They work when using cmd.php as well as the directories are picked up by php/snmp.

So my question is this. How do I add other MIB directories to the search path for spine? I'm not going to break everything on the system by moving these MIBs to /usr/share/snmp/mibs, so it would make sense to just include them in the SNMP MIB path. But how?

Is this a bug and/or should I be filing this in the bug tracking system or is this feature missing by design?

1) you should upgrade to cacti/spine 0.8.8c -- just in case.
2) Typically its better if you use the OID instead of the conceptual name. To test, if you switch PowerNet-MIB::upsAdvInputLineVoltage.0 to its OID, does the spine error go away? If so, then yes please create a bug http://www.cacti.net/bugs.php

Just tested - no change with 0.8.8c

Changing the OID to numeric instead of textual results in a successful poll, so looks like there is indeed a problem. I'll log a bug now.
