I'm not sure how you're getting metrics from Cassandra to Prometheus, or if you're using the JMX exporter agent, how your configuration might be rewriting metric names, so I'll just refer you to the document of JMX metrics in the hope you can infer what you need from that. http://cassandra.apache.org/doc/latest/operating/metrics.html There are metrics that can tell you the number of queries being made, broken down by request type: http://cassandra.apache.org/doc/latest/operating/metrics.html#client-request-metrics Use table metrics if you want the rates of reads/writes against the data that those client requests translate into: http://cassandra.apache.org/doc/latest/operating/metrics.html#table-metrics Another measure of throughput you might want to monitor is compaction. For example, the rate of compactions, and the number of bytes compacted, are both of interest. Pending compactions can give you an idea of saturation. http://cassandra.apache.org/doc/latest/operating/metrics.html#compaction-metrics Hope this helps. -- Eric Evans john.eric.ev...@gmail.com --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@cassandra.apache.org For additional commands, e-mail: user-h...@cassandra.apache.org
