Cabot is a free, open-source, self-hosted infrastructure monitoring platform that provides some of the best features of PagerDuty, Server Density, Pingdom and Nagios without their cost and complexity. (Nagios, I'm mainly looking at you.)
It provides a web interface that allows you to monitor services (e.g. "Stage Redis server", "Production ElasticSearch cluster") and send telephone, sms or hipchat/email alerts to your on-duty team if those services start misbehaving or go down - all without writing a line of code. Best of all, you can use data that you're already pushing to Graphite/statsd to generate alerts, rather than implementing and maintaining a whole new system of data collectors.
You can alert based on:
We built Cabot as a Christmas project at Arachnys because we couldn't wrap our heads around Nagios, and nothing else out there seemed to fit our use case. We're open-sourcing it in the hope that others find it useful.
Cabot is written in Python and uses Django, Bootstrap, Font Awesome and a whole host of other goodies under the hood.

For those who want to contribute:
My dog is called Cabot and he loves monitoring things. Mainly the presence of food in his immediate surroundings, or perhaps the frequency of squirrel visits to our garden. He also barks loudly to alert us on certain events (e.g. the postman coming to the door).
It's just a lucky coincidence that his name sounds like he could be an automation tool.
