At work we’ve got some Tripp Lite battery backups. I wanted to add some of the data they have to our MRTG graphing (input voltage, output load, temperature, etc) so I started by using snmpwalk to see what data the Tripp Lite exposed via SNMP. Unfortunately I didn’t get MIB text descriptions, just the numbers. So after looking around for a bit I found the CD that came with the devices, it had some two MIB files, trpplite.mib and Rfc1628.mib. I dumped these into /usr/share/snmp/mibs on my PowerBook figuring that snmpwalk would just pick up on the extra MIB information. That turned out to not be the case. For some reason snmpwalk has a special option to tell it to use all of the MIB definitions. Go figure. After all of this I can now run ’snmpwalk -m ALL -Os -c public -v 1 tripplitehost’ and get back all of the SNMP information available.
