>                 Key: JAMES-2131
>                 URL: https://issues.apache.org/jira/browse/JAMES-2131
>             Project: James Server
>          Issue Type: Improvement
>          Components: cassandra
>            Reporter: Tellier Benoit

> While reading some blog posts regarding the Cassandra Java driver I came to realise it also uses the metrics framework.
> Integrating it in James would allow to report:
>  - Cassandra request execution time
>  - Cassandra request execution rate
>  - Cassandra request execution count
>  - Various queu size
> This would allow a finer management of James, winner diagnostic, and a better knowledge of our application. A Grafana dashboard for this is a must have!
> We can use : 
> {code:java}
> metricRegistry.registerAll(
>    session.getCluster().getMetrics().getRegistry())
> {code}
> Which can be done in a dedicated Guice module.
