Im checking a LACP interface where I have NIC1 and NIC2

To make things simple: Lets say 1 is up and 0 is down. Also lets make up the OIDs…

1.2.3.4.5.6.7.8.9.9.9.1 is interface one with it returning a 1 or 0
1.2.3.4.5.6.7.8.9.9.9.2 is interface two with it returning a 1 or 0

Ideally:

./check_snmp -H myfqdn.host.com -o 1.2.3.4.5.6.7.8.9.9.9.1 -o 1.2.3.4.5.6.7.8.9.9.9.2 -P 3 --seclevel=authPriv --secname=user --authproto=SHA --authpasswd='blahblah' --privpasswd='blahblah' --privproto=AES -n

Up till that, everything is understandable.

Here is my thing: I want to return a warning, crit, ok, depending on a conditional: If one interface (either one) is down, it should return a warning. if both are down, it should return a crit and if both are up, it should return a ok. anything else: unknown.

How do I do this?

I don't see a way to return both a warning or critical in that specific manner. Unless I am mistaken.

There isn't a way to pass unknown as far as I know.

Currently this is how I am testing it. But my values change greater than just 0 to 1.

From the help options of check_snmp:

Code: Select all

Notes:
 - Multiple OIDs (and labels) may be indicated by a comma or space-delimited
   list (lists with internal spaces must be quoted).
 - See:
 https://www.nagios-plugins.org/doc/guidelines.html#THRESHOLDFORMAT
 for THRESHOLD format and examples.
 - When checking multiple OIDs, separate ranges by commas like '-w 1:10,1:,:20'
 - Note that only one string and one regex may be checked at present
 - All evaluation methods other than PR, STR, and SUBSTR expect that the value
   returned from the SNMP query is an unsigned integer.
