Evaluation of Cassandra ring

I am not sure if this is the right place to post this but let me know if not. So, I have a Cassandra ring with 16 nodes which contains ~1.1 billion records. I would like to know how can I evaluate this cluster. What kind of metrics are important to collect and how (i.e. memory consumption during the inserts?)? For example writing/reading speed? Compression ratio? Compacted partitions? Should I also use Jconsole somehow?

Feel free to post any documentation or links.

Important metrics to watch for on an Apache Cassandra cluster:

  • Java heap usage
  • reads/sec
  • writes/sec
  • current compactions
  • disk space
  • disk latency
  • disk IOPS
  • nodes down
  • CPU (although, I wouldn't alert on it)

That should be a good enough list to help you get started. Check out the Monitoring page from the official docs for more information and additional metrics.
