Simple service monitoring using Go and MessageBird

For a while I have been looking for a simple service monitoring tool that didn’t cost anything to run and gave me what I wanted to know: when services are in trouble. Everything I found was either too complicated or partially filled what I was looking for. So I decided to quickly write something up and created go-monitor. TL;DR go-monitor is a simple service monitoring tool. Its primary function is to monitor a list of services specified by the user, and then to notify one or many users if/when these services go down. »
