@call_krushna,

You need to run this script from your Nagios libexec directory.
For my example, it is /usr/local/nagios/libexec

You can find missing utils.sh there: http://n2rrd-wiki.diglinks.com/display/n2rrd/utils.sh

#! /bin/sh

STATE_OK=0
STATE_WARNING=1
STATE_CRITICAL=2
STATE_UNKNOWN=3
STATE_DEPENDENT=4

if test -x /usr/bin/printf; then
ECHO=/usr/bin/printf
else
ECHO=echo
fi

}

We had to change only one thing:

Before:
free=${freeunit:0:-2}

Returns the following error:
"line 101: -2: substring expression Molina:

This works very well for me. I've created a github repo for this at https://github.com/customink/nagios-nrpe-check_glusterfs

I've checked in carrillm's mod to support TB sized gluster volumes, and an additional mod to output all errors on a critical alarm, not just free space. That way a lack of free space alert won't hide the fact that you're volume has bricks in a healing state, for instance.

Feel free to submit pull requests via git.

Thanks for the great work, Mark.

I tested with gluster 3.4.2 and it's working very well i just modificate the script to manage TB volume with freespace on TB :

so on disk part of script replace this:

Disk)
key=${field[@]:0:3}
if [ "${key}" = "Disk Space Free" ]; then
freeunit=${field[@]:4}
free=${freeunit:0:-2}
unit=${freeunit#$free}
if [ "$unit" != "GB" ]; then
Exit UNKNOWN "unknown disk space size $freeunit"
fi
free=$(echo "${free} / 1" | bc -q)
if [ $free -lt $freegb ]; then
freegb=$free
fi
fi
;;


by this :

Disk)
key=${field[@]:0:3}
if [ "${key}" = "Disk Space Free" ]; then
freeunit=${field[@]:4}
free=${freeunit:0:-2}
freeconvgb=`echo "($free*1024)" | bc`
unit=${freeunit#$free}
if [ "$unit" = "TB" ]; then
free=$freeconvgb
unit="GB"
fi
if [ "$unit" != "GB" ]; then
Exit UNKNOWN "unknown disk space size $freeunit"
fi
free=$(echo "${free} / 1" | bc -q)
if [ $free -lt $freegb ]; then
freegb=$free
fi
fi
;;



Thanks a lot
