Bosun is an open-source monitoring and alerting system designed for diverse users, including businesses and government organizations. It utilizes a specific domain language to create and evaluate alerts, enabling users to generate detailed notifications. One of its key features is the ability to test alerts against historical data, which streamlines the development process and minimizes alert noise before deployment. Bosun is compatible with various operating systems, including Linux, Windows, and Mac, ensuring wide accessibility.

This program supports arbitrary dimensions and aggregations, allowing for a flexible approach to monitoring. The Scollector component automatically detects new services and begins metric collection, ensuring that alerts can be applied to these services with minimal maintenance. Bosun also integrates seamlessly with Docker, enhancing its utility in modern IT environments. Documentation is available for users seeking training on the system.
