Uptime Monitor

A simple uptime monitor that checks if a host is up or down.

Inspiration

I wanted to monitor hosts in my network in similar way to how UptimeRobot does it.

Usage

Start service with WSGI, e.g. gunicorn:

gunicorn wsgi -b <ip-address>:<port> --chdir /path/to/uptime-monitor --worker-class eventlet

Also, remember to add following command to crontab to run the monitor every minute.

* * * * * /path/to/python -m flask --app /path/to/uptime-monitor/app/app.py iputils ping

Updating

To update the monitor:

1. pull the latest changes from the repository,
2. upgrade database schema:

   /path/to/python -m flask --app /path/to/uptime-monitor/app/app.py db upgrade
   # or
   flask db upgrade # if you are in the root of the project and using correct venv

3. restart the service.

Management

All commands have to be run from the root of the project.

Add a host

flask manage add <ip-address> [--name <friendly-name>]

Update name of a host

flask manage set-name <new-name> --to <ip-address>

Remove host

flask manage remove <ip-address>
