Clean up check_snmp output

[thenomad]

the output from check_snmp while correct is pretty nasty looking.
I simply want the status of the query not the whole query as an output

Code: Select all

/usr/bin/snmpget -Le -t 1 -r 5 -m '' -v 1 [authpriv] no.no.no.no:161 .1.3.6.1.4.1.9.9.171.1.2.1.1.0
iso.3.6.1.4.1.9.9.171.1.2.1.1.0 = Gauge32: 0
SNMP OK - 0

I just want SNMP OK - 0

Thanks

You can make a wrapper script that calls check_snmp, and then pipes the output into a tail -n1 command.

Code: Select all

#!/bin/bash

check_snmp something something something | tail -n1

Then you set your command definition to use that script instead of check_snmp. Obviously substitute "something something something" for more useful information.

works from the terminal ok but I seem not to be able to build the pipe into the service as it causes the command to malform from the service configuration

Code: Select all

COMMAND: /usr/local/nagios/libexec/check_snmp -H no.no.no.no  -v 2c -C myspace -o .1.3.6.1.4.1.9.9.171.1.2.1.1.0 -w3 -c6   \| tail -n1
OUTPUT: Usage:
check_snmp -H <ip_address> -o <OID> [-w warn_range] [-c crit_range]
[-C community] [-s string] [-r regex] [-R regexi] [-t timeout] [-e retries]
[-l label] [-u units] [-p port-number] [-d delimiter] [-D output-delimiter]
[-m miblist] [-P snmp version] [-L seclevel] [-U secname] [-a authproto]
[-A authpasswd] [-x privproto] [-X privpasswd]
