[asterisk-users] Which tool to automatically restart Asterisk ?

[Victor Villarreal]

Hi, Oliver.

Maybe something like this (add this script to your crontab):

------------------------8<--------------------------

#!/bin/bash
#
# File:         asterisk-watchdog.sh
# Date:         2015.05.26
# Build:        v1.0
# Brief:        Secuencia para monitorizar procesos.
#
# ${PATH}: Variable de entorno con las rutas a los ejecutables.
PATH=/bin:/sbin:/usr/bin:/usr/sbin

# ${DAEMON}: Demonio a monitorizar.
DAEMON="asterisk"

# ${MSG}: Cuerpo del mensaje a enviar por mail.
MSG="$(date '+%F %T'): ${DAEMON} se ha caido!"

pidof ${DAEMON} > /dev/null 2>&1

[ $? -ne 0 ] && { echo ${MSG}; service ${DAEMON} start; }

exit 0
