[jira] [Created] (CASSANDRA-17235) Add diagnostic events for unavailable errors

Stefan Podkowinski created CASSANDRA-17235:
----------------------------------------------

             Summary: Add diagnostic events for unavailable errors
                 Key: CASSANDRA-17235
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-17235
             Project: Cassandra
          Issue Type: New Feature
          Components: Observability/JMX
            Reporter: Stefan Podkowinski
            Assignee: Stefan Podkowinski


Errors from unavailables during query execution lack important details on the context why the error occurred. Emitting diagnostic events on unavailables will allow you to attach to the instance during troubleshooting and observe the type of operation (what kind of reads/writes), keyspace replication settings and down nodes as seen by the instance throwing the error.
