Customizable alerts and notifications via email, SMS, chat apps, etc.
Integration with commonly used data sources like Graphite, OpenTSDB, InfluxDB, etc.
Custom dashboard creation for data visualization
Anomaly detection algorithms to automatically detect issues
EXTENSIBLE plugin architecture to add new functionality and data sources
Bosun was created to meet the complex monitoring needs of Stack Exchange's large-scale production infrastructure. It offers more advanced analytics and customizability than many commercial monitoring tools. The open-source model also allows users to extend Bosun to fit their specific use cases.
While the configuration and use of Bosun has a learning curve, it is a very powerful and scalable monitoring system for organizations with complex infrastructures and monitoring needs.
