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.
- Save time by testing alerting against historical data and reduce alert noise before an alert goes into production
- Supports querying OpenTSDB, Graphite, and Logstash-Elasticsearch
- Create notifications using Bosun's template language: include graphs, tables, and contextual information
