Riemann Reviews

Riemann Description

Riemann aggregates events from applications and servers using a powerful stream processing language. Send an email to every exception in your app. Monitor the latency distribution for your web app. You can see the top processes on any host by memory and CPU. Combine statistics from each Riak node within your cluster and forward them over to Graphite. Follow user activity from second-to-second. Riemann is a low-latency, temporary shared state that can be used in systems with many moving parts. Riemann streams are functions that accept events. Clojure program, Riemann's configuration has a simple syntax that is easy to understand, consistent, and extensible. Configuration-as-code minimizes boilerplate and gives you the flexibility to adapt to complex situations. Riemann can give you as much or little information as you need. You can throttle or roll up multiple events in one message. You will receive emails about exceptions in the code, provider downtime or latency spikes. PagerDuty integration is possible for SMS and phone alerts.
