SNMPwalk and data units

[jpipitone]

I used the configuration wizard to perform an snmpwalk, and I am monitoring interfaces on a remote Sonicwall. Nagios is pulling the values correctly, however I'd like to translate the values into human readable format - such as megabytes.

For example - the values for our interfaces look simiar to: 1914976279

The counters appear to be of type "Counter32"

How can I translate this into MB? When NagiosXI displays the oid values after an snmpwalk, there are a few text fields that I can enter values into - one that stuck out was Data Units. How can I do this?

Thank you

If this is something such as interface speed, I would highly suggest trying the Network switch and router wizard. It will handle all of this for you! Otherwise you will likely have to write a wrapper script for check_snmp that will modify the output as you need. Unfortunately check_snmp does not provide functionality to manipulate the data once it is received. The only other option would be to use the --rate flag and its fellow modifiers to get a delta of the two most recent checks. You could certainly do it, but it is not the same value as you are currently getting.

Well that seems to be working great - thank you!
