[mrtg] SNMP v2 issues with queries

Fri Apr 12 00:15:18 CEST 2013
Actually I didn't use cfgmaker. I'm generating the config files using a
perl script that I wrote using data (hostname, community, interface,
maxbytes, title, etc.) from a MySQL database that I've been using
successfully for years. It's just recently that the system has started
failing to find the interfaces when querying devices using SNMP v2. No
changes were made to the mrtg binary when this issue started cropping and
it's happening across multiple devices.
Thanks,
