py-nagios-wa is a small Python script that enables sysadmins to receive Nagios notifications on WhatsApp. Teams can also configure it to send notifications to group chats.

• Python 2.7
• Yowsup 2.2

A virtualenv is recommended. Dependencies can easily be installed through pip. For rapid installation, the setup script can also be used.

Simple set up a new virtualenv and install the requirements.txt through pip. Alternatively, for easy installation, you can simply execute the setup script. This will set up a new virtualenv for you, and install all dependencies by running pip in that new virtualenv.

$ chmod +x ./setup_env.sh
$ ./setup_env.sh

Configuring py-nagios-wa

You will first need to create your local_settings.py. Have a look at example_settings.py and configure your loca settings accordingly. For easy installation, you can also copy the example configuration into the local settings file. You'll then only have to change your login credentials and the DEFAULT_RECIPIENTS.

• CREDENTIALS - Your Whatsapp username and base64 password.
• DEFAULT_RECIPIENTS - Notifications will be sent to these jids.
• HOST_NOTIFICATION - Your host notification template.
• SERVICE_NOTIFICATION - Your service notification template.

To test out whether your configuration is working, you can simply execute the notify script. This will send a default notification to the default recipients configured in your local_settings.py.

A succesful configuration will yield something like this:

$ source env/bin/activate
$ cd src/
$ python notify.py
Succesfully connected to the WhatsApp service.

Configuring Nagios

Configuring Nagios should at this point not be too difficult. Edit your commands.cfg and add the following entries:

define command {
    command_name    host-wa
    command_line    /path-to/py-nagios-wa/env/bin/python /path-to/py-nagios-wa/src/notify.py host
}

define command {
    command_name    service-wa
    command_line    /path-to/py-nagios-wa/env/bin/python /path-to/py-nagios-wa/src/notify.py service
}

Don't forget to command line paths, of course :-) That's it - you're all set to use WhatsApp for your Nagios notifications now!
