Loading MIB Definitions - Help me get out of SNMP Hell!

[joe at gonetforward.com (Joe Renwick)]

Problem solved.  NANOG is awesome!  Thanks much to all who assisted.

It is actually quite easy to load the MIB definitions to you Ubuntu machine.
 I just downloaded the complete Cisco MIB tree to make life easier "
ftp://ftp.cisco.com/pub/mibs/v2";.  Downloaded the "v2.tar.gz file".
 Unpacked the MIB(s) into '$HOME/.snmp/mibs' directory and life is good.
 Note that when the tarball unpacks it creates a weird directory structure.
 Just find the .my files and move them to $HOME/.snmp/mibs.

Here is success:

*jozo at crdtools:~/.snmp$ snmpget -v 1 -c 'ptasa2etb' 192.168.10.2
CISCO-PROCESS-MIB::cpmCPUTotal5min.1*
*CISCO-PROCESS-MIB::cpmCPUTotal5min.1 = Gauge32: 0*

Now that my servers understand the MIB I can get the numerical OID for
Cacti:

*jozo at crdtools:~/.snmp$ snmptranslate -On
CISCO-PROCESS-MIB::cpmCPUTotal5min.1*
*.1.3.6.1.4.1.9.9.109.1.1.1.1.5.1*

Hope this helps someone down the road.

Cheers,

Joe
