Nagios Plugin To Check XenServer License

with 4 comments


Hi guys,
since xenserver license is active for 1 year, happens sometimes that i forgot to reactivate the license, and then if u shut down the vm machine they don’t start up if license is expired, i create a nagios plugin to check the days remaining for the license.

here’s the script updated thanks to Martin:

#!/bin/bash
#
# retrieve remaining day for xenserver license
#
# Date: 2010-04-15
# Author: Filippo Zanardo
#

# get arguments

while getopts ‘w:c:hp’ OPT; do
case $OPT in
w) int_warn=$OPTARG;;
c) int_crit=$OPTARG;;
h) hlp=”yes”;;
*) unknown=”yes”;;
esac
done

# usage
HELP=”
usage: $0 [ -w value -c value -h ]

syntax:

-w –> Warning integer value
-c –> Critical integer value
-h –> print this help screen

if [ “$hlp” = “yes” -o $# -lt 1 ]; then
echo “$HELP”
exit 0
fi

# get license expiry date
EX=`xe host-license-view |grep expiry | awk ‘{ print $2; }’`
DEX=${EX:0:8}

today=`date +%Y%m%d`
timeStampToday=`date +%s -d $today`
timeStampOfPast=`date +%s -d $DEX`
secondsInDay=86400
dayDiff=`echo \($timeStampOfPast – $timeStampToday\) / $secondsInDay – 1 | bc`

#dayDiff is the day remaining

OUTPUT=”$dayDiff days remaining”

if [ -n “$int_warn” -a -n “$int_crit” ]; then

err=0

if (( $dayDiff <= $int_warn )); then
err=1
elif (( $dayDiff <= $int_crit )); then
err=2
fi

if (( $err == 0 )); then

echo -n "OK – $OUTPUT"
exit "$err"

elif (( $err == 1 )); then
echo -n "WARNING – $OUTPUT"
exit "$err"

elif (( $err == 2 )); then

echo -n "CRITICAL – $OUTPUT"
exit "$err"

fi

else

echo -n "no output from plugin"
exit 3

fi
exit

just copy it save with some name for example check_xenlicense.sh in the nagios plugins directory and configure to use for example with nrpe.
basic usage is:

check_xenlicense.sh -w 15 -c 5

where “w” is the days remaining for a warning message and “c” is the days remaining for a critical message

if you don’t use nagios you can use as a simple script in a cron job or whatever.

Maybe if someone find this useful i will add the ability to send an email notification.

Cheers
