GlusterFS checks

@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

print_revision() {
echo "$1 v$2 (nagios-plugins 1.4.13)"
$ECHO "The nagios plugins come with ABSOLUTELY NO WARRANTY. You may redistribute\ncopies of the plugins under the terms of the GNU General Public License.\nFor more information about these matters, see the file named COPYING.\n" | sed -e 's/\n/ /g'
}

support() {
$ECHO "Send email to nagios-users@lists.sourceforge.net if you have questions\nregarding use of this software. To submit patches or suggest improvements,\nsend email to nagiosplug-devel@lists.sourceforge.net.\nPlease include version information with all correspondence (when possible,\nuse output from the --version option of the plugin itself).\n" | sed -e 's/\n/ /g'
}

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

I am getting below error while running the script .

./check_glusterfs -v testvolume -n 2

./check_glusterfs: line 27: ./utils.sh: No such file or directory
./check_glusterfs: line 54: CRITICAL: no bricks found: command not found


Thanks and regards
