A nagios plugin for checking asterisk using AMI
Inspired by https://github.com/nicolargo/nagisk

Add a AMI user in /etc/asterisk/manager.conf:

[nagios]
secret = your_secret_password
deny=0.0.0.0/0.0.0.0
# allow only from localhost
permit=127.0.0.1/255.255.255.0
# we just need the read reporting permission
read = reporting
writetimeout = 5000

Adjust parameters in nagisk2.pl:

use constant R_PORT => 5038;
use constant IP_ADDR => 'localhost';
use constant AMI_USER => 'nagios';
use constant AMI_PASS => 'your_secret_password';

And finally, copy this file to $nagios_plugindir (usually /usr/lib/nagios/plugins) and set up a command.

• pjsip_outbound_registry: Checks an outbound trunk.

Besides, being useful as is (hopefully) - this script should also serve as skeleton for other checks. If you follow this simple recipe you should be able to easily implement your own checks:

• Insert a check method according to the template in the header of nagisk2.pl.
• Add your command to initial the for()-block (there is a commented-out example).
• Add your command to the show_help() function.
• Create a pull request with your extension :)
