Bosun is an open-source, MIT-licensed monitoring and alerting system by Stack Exchange that provides an expressive domain-specific language for evaluating alerts and creating detailed notifications, with the ability to test alerts against historical data for faster development. It can query OpenTSDB, Graphite, and Logstash-Elasticsearch, runs on Linux, Windows, macOS, or any OS supported by Go, and includes scollector, an agent that auto-detects new services and metrics. The project offers quick-start docker images and prebuilt binaries, but as of February 2025 Bosun is no longer maintained.
