We are pleased to announce that Two Sigma is open-sourcing Satellite, a Mesos monitoring and alerting application with self-healing capabilities. Satellite makes it easy to continuously monitor your cluster, automatically add and remove slaves, and alert you via email or PagerDuty if your cluster becomes unresponsive. Satellite is able to do this by embedding Riemann, leveraging its powerful and simple stream processing DSL.
We are releasing Satellite under Apache v2.0. Full source and documentation is on Github: <https://github.com/twosigma/satellite>. We welcome comments and contributions! You can contact us through this thread, email <[email protected]>, or Twitter <@sabraham>. Sunil Abraham Two Sigma Open Source, LLC
