Zabbix - SMS with Gammu

Create an sms script (and make it executable) on the zabbix server in the AlertScriptsPath (=/etc/zabbix/alert.d/ on ubuntu)

#!/bin/sh
HOME=/etc
PATH=/bin:/sbin:/usr/bin:/usr/sbin
LOGFILE="/var/log/zabbix-server/zabbix-sms.log"
echo "Recipient='$1' Message='$3'" >> ${LOGFILE}
MOBILE_NUMBER=`echo "$1" | sed s#\s##`
# Log it
echo "echo $3 | /usr/bin/sudo /usr/bin/gammu --sendsms TEXT ${MOBILE_NUMBER}" >>${LOGFILE}
# Send it
echo "$3" | /usr/bin/sudo /usr/bin/gammu --sendsms TEXT "${MOBILE_NUMBER}" 1>>${LOGFILE} 2>&1
# EOF

Add:

zabbix ALL = NOPASSWD:/usr/bin/gammu

to the sudoers to make it available for the zabbix user

Configure a media type (menu administration) with the same name as your script (without path, without parameters)

Link this media type to a user (menu administration) and use the phone number as Send to parameter.

Dont forget to give zabbix a shell in /etc/passwd and permissions to write in the log file...

Note: if you have gammu configured as a daemon use gammu-smsd-inject instead of gammu --sendsms or

echo "$3" > /var/spool/gammu/outbox/OUT"${MOBILE_NUMBER}".txt

If you are using the files backend

I use a hawaii usb gsm modem and my /etc/gammurc looks like this:

[gammu]
port = /dev/ttyUSB0
model =
connection = at19200
synchronizetime = yes
logfile =
logformat = nothing
use_locking =
gammuloc =
