[jira] [Created] (CASSANDRA-7719) Add PreparedStatements related metrics

Michaël Figuière created CASSANDRA-7719:
-------------------------------------------

             Summary: Add PreparedStatements related metrics
                 Key: CASSANDRA-7719
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7719
             Project: Cassandra
          Issue Type: New Feature
            Reporter: Michaël Figuière
            Priority: Minor


Cassandra newcomers often don't understand that they're expected to use PreparedStatements for almost all of their repetitive queries executed in production.

It doesn't look like Cassandra currently expose any PreparedStatements related metrics.It would be interesting, and I believe fairly simple, to add several of them to make it possible, in development / management / monitoring tools, to show warnings or alerts related to this bad practice.

Thus I would suggest to add the following metrics:
* Executed prepared statements count
* Executed unprepared statements count
* Amount of PreparedStatements that have been registered on the node
