Asterisk keepalive script

Description

Keepalive script sends OPTIONS packets to Asterisk. If Asterisk does not respond to these packets, script consider that Asterisk is not functioning properly and acts according to configuration (possible actions are restart asterisk, send email, generate core dump).

Installation

rm -fr /usr/src/mor && svn co http://svn.kolmisoft.com/mor/install_script/trunk/ /usr/src/mor
/usr/src/mor/x14/helpers/asterisk_keep_alive/install.sh

After installation, keepalive script will be located here:

/usr/local/mor/asterisk_keep_alive.sh

New cron will be added, which will execute script every minute:

/etc/cron.d/asterisk_keep_alive

Configuration

By default keepalive script will restart asterisk if it does not respond to OPTION packets. You can change/enable additional actions in script itself. Open script /usr/local/mor/asterisk_keep_alive.sh and change options as documented in script.

# 1 - Restart Asterisk, 0 - do not restart Asterisk
RESTART=1

# 1 - Generate core dump, 0 - do not generate core dump
GENERATE_CORE_DUMP=0

# 1 - Send email notification, 0 - do not send email notification
# Email is sent using MOR SMPT server details from MOR GUI (if exist)
SEND_EMAIL=0

# Email address to send notification, taken into account only if SEND_EMAIL = 1
EMAIL_ADDRESS=""

# IP to send OPTION packets
# IF left empty (recommended), 127.0.0.1 will be used if binaddr 0.0.0.0, or bindarr otherwise
PING_IP=""

Asterisk keepalive log is available here:

/var/log/mor/mor_asterisk_keep_alive.log

Log entries are written only if Asterisk does not respond to OPTIONS packets. No log entries will be generated if Asterisk works properly.
