Apache Cassandra uses the Yammer Metrics library for tracking client request metrics since version 1.1. The library offers tools like Counters, Gauges, and Timers with an easy-to-use API. Metrics can be exported to files or other systems periodically using official "metrics reporters" or community-developed ones. In this article, the author demonstrates how to configure Cassandra to report metrics to Graphite using a java agent. New metrics provide more information than previous versions and are easily integrated with other systems.
