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.
Project Status (2024-05)
Skyscanner is in the process of migrating from an open source monitoring solution to a SaaS vendor. We are looking for users or contributors interested in becoming maintainers. Please see this Github issue for more information.
Want to jump right in? Follow our quick start tutorial to get Bosun, OpenTSDB, and scollector up quickly using our published docker images.
Download the prebuilt binaries for Bosun and our optional but valuable monitoring agent (Currently works only with OpenTSDB) scollector for Windows, Linux, and Mac.
Join us in our Slack room. Get an invite. You can open issues on GitHub to report bugs or discuss new features.
Use Bosun's flexible expression language to evaluate time series in an exacting way
Create notifications using Bosun's template language: include graphs, tables, and contextual information
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
Use our agent scollector to get monitoring of Windows, Linux, and many common applications
Supports arbitrary dimensions (not just host based), aggregations, and automatically incorporating new tags (hosts, services, ..) as they appear
Scollector auto detects new services and starts sending metrics immediately; properly designed alerts will apply to these new services which reduces maintenance
