Basic site monitoring in a single Python script, with no dependencies.

• Python 2 and Python 3 compatible
• No external deps
• Pushover notifications

• Edit the config in critikl.py

config = {
    'interval': 60,  # How often to perform checks (in seconds)
    'pushover': {
        'app_token': 'your-pushover-app-token',
        'user_key': 'your-user-key',
    },
    'sites': {
        'example.com',  # Just the domain
        'https://example.com/api',  # OR a full url
    }
}

• Start the script

$ python critikl.py

• (Optional) Use a process manager (e.g. circus)

  A. Install circus

  $ sudo pip install circus

  B. Create the circus config file

  Edit circus.ini and modify the path where you put the critikl.py script

  $ nano circus.ini

  Create circus configuration file

  $ sudo cp circus.ini /etc/circus.ini

  Start circus (circus will start critikl.py)

  circusd /etc/circus.ini

  C. Start circus on system startup using upstart

  $ sudo cp circus.conf /etc/init/circus.conf
  $ sudo service circus start

That's it. You will now receive Pushover notifications when one of your sites is down.
