Hi,

I'm using check_ifoperstatus to get the status of host interface. However, this does not graph the status so that you can check historically when an interface does down.

How can I enable perfdata output from this check_ifoperstatus check command? There does not seem to be an option for this.

This plugin doesn't have performance data as there is not a numeric value to associate with. You can check historical values in the State History report.

Hi,

There is the numeric value of the return status code (0,1,2,3) that could be graphed. I think that is all I need to be graphed.

I have found the State History report but this just shows a table fo the states, not a nice visual graph that I would like.

A workaround I can think of is piping the results to a script that adds the perfdata text based on the returned status code.

Yes, you could make a wrapper script.

Here's the information on the format of the performance data

Hi,

Rather than a 'wrapper' script I wrote a 'check_ifoperstatus_perfdata.sh' script to pipe to:

All this does is repeat the input it gets, and then creates the perfdata based on what it finds and exits with the appropriate code. I don't need any thresholds yet, so this is good enough for me, for now.
So the check command would be something like this: I'll probably create a custom check command that uses this format/template.

Code: Select all

#!/bin/bash
read input
echo $input
case "$input" in
  *OK*)
    echo "| status=0"
    exit 0
    ;;
  *WARNING*)
    echo "| status=1"
    exit 1
    ;;
  *CRITICAL*)
    echo "| status=2"
    exit 2
    ;;
  *UNKNOWN*)
    echo "| status=3"
    exit 3
    ;;
esac

So the check command would be something like this:

Code: Select all

/usr/local/nagios/libexec/check_ifoperstatus -H <HOST> -C <COMMUNITY> -d <interface> -v 2 -p 161 | /usr/local/nagios/libexec/check_ifoperstatus_perfdata.sh

I'll probably create a custom check command that uses this format/template.

sounds good
