Zabbix SMS queuing.

I had a problem with the sms program we use just dropping sms's if you tried to send too many at one time.

I'm using the following script in zabbix to interface with gammu the sms tool.

#!/usr/bin/env bash

LOCKFILE=/tmp/sms.lock

LOCKED="false"

echo "waiting for lock" |logger -t "sms" -i -p local3.info

while [ "${LOCKED}" = "false" ]

do

if [ ! -f ${LOCKFILE} ]; then

echo "$$" > ${LOCKFILE}

fi

if [ "$$" = "`cat ${LOCKFILE}`" ]; then

LOCKED="true"

fi

done

echo "got lock." |logger -t "sms" -i -p local3.info

trap "{ rm -f $LOCKFILE ; exit 255; }" EXIT

echo "sending sms to: $1" |logger -t "sms" -i -p local3.info

echo "$2 $3 $4 $5 $6 $7 $8 $9" | /usr/bin/gammu sendsms TEXT $1 > /dev/null 2>&1

exit 0

Maybe someone else will find this useful.
