Help with thresholds on check_snmp calculation wrapper

[nbradshaw45]

Hello -

I needed a way to take a value and divide it by 100 - so I found an article that explained how to use awk to come up with the needed value - and this works great - however, it does not return the warning;critical values.

Code: Select all

[icode]#!/bin/bash
hostaddress=$1
/usr/local/nagios/libexec/check_snmp -H $hostaddress -C R3adM3 -m ALL -o .1.3.6.1.4.1.7309.4.1.1.1.0 | awk -F'|' '{split($1,array_left,"-");} {split($2,array_right,"=");} {print array_left[1]"- "array_left[2]/100"|"array_right[1]"="array_right[2]/100;}'[/icode]

How can I adapt this bash script to use the proper exit codes for warning and critical?

Much appreciated!

You would need to have the plugin run again, executing normally do display the proper exit code / other data, or write a full on wrapper to handle your logic for warning / critical as well.

Feel free to base it off something like this - https://github.com/rcknag/nagios-plugin ... netstat.sh

Thanks for the response -

I have put the plugin together - however, the output is always "CRITICAL - 54". Even when I don't set -w -c...it always returns CRITICAL.

[root@CRLNAGP01 libexec]# ./check_snmp_argus_battery_charge_in_volts.sh 10.150.101.20 -w9000 -c10000
CRITICAL - 54

Code: Select all

#!/bin/bash
hostaddress=$1
#snmp=$(/usr/local/nagios/libexec/check_snmp -H $hostaddress -C R3adM3 -m ALL -o .1.3.6.1.4.1.7309.4.1.1.1.0 | awk -F'|' '{split($1,array_left,"-");} {split($2,array_right,"=");} {print array_left[1]"- "array_left[2]/100"|"array_right[1]"="array_right[2]/100;}')

snmp=$(/usr/local/nagios/libexec/check_snmp -H $hostaddress -C R3adM3 -m ALL -o .1.3.6.1.4.1.7309.4.1.1.1.0 |cut -b 11-14)

#snmp=$(/usr/local/nagios/libexec/check_snmp -H $1 -C 'mycommunity string' -o .1.3.6.1.4.1.7309.4.1.1.1.0|cut -b 11-14)

I would add an debug to echo what $snmp is equal to before dividing by 100.

Code: Select all

value=$(expr $snmp / 100)

[nbradshaw45]

Thanks for the reply...yes - I can echo the original value just fine.

I think what is going on is that the -w -c flags are not being interpreted by my script...can you take a look and see why it is not passing - mistake in my script I'm Sure.

[rkennedy]

Is it debugging to what you'd expect? Try this with spaces after the vars - ./check_snmp_argus_battery_charge_in_volts.sh 10.150.101.20 -w 9000 -c 10000 - to take -w / -c out you could always just get sloppy with $2 and $3.

Just checking in since we have not heard from you in a while. Did @rkennedy's post clear things up or has the issue otherwise been resolved?
