> It would be helpful to have read and write metrics for each consistency level to help clients track query rates per consistency level. It's quite common to forget to set e.g. a config param in the client and use the wrong consistency level. Right now the only way to find out from Cassandra is to use tracing. It would also be helpful to track latencies for different consistency levels to estimate the cost of e.g. switching from LOCAL_QUORUM to QUORUM reads.
