BOSUN

is an open-source, MIT licensed, monitoring and alerting system by Stack Exchange. It has an expressive domain specific language for evaluating alerts and creating detailed notifications. It also lets you test your alerts against history for a faster development experience... Skyscanner is delighted to announce that as of 18th November 2019, we'll be officially taking over Bosun's ownership and maintainership from Stack Exchange (home of stackoverflow.com)... We would like to thank StackExchange for their time, ensuring a smooth transition process, and for everyone's hard work and input towards making this project a success. A special thanks to Kyle Brandt for initiating the Bosun project and leading it for many years.
