[jira] [Created] (CASSANDRA-11992) Consistency Level Histograms

Ryan Svihla created CASSANDRA-11992:
---------------------------------------

             Summary: Consistency Level Histograms
                 Key: CASSANDRA-11992
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11992
             Project: Cassandra
          Issue Type: New Feature
            Reporter: Ryan Svihla
            Priority: Minor


It would be really handy to diagnose data inconsistency issues if we had a counter for how often a given consistency level was attempted on coordinators (could be handy cluster wide too) on a given table.

nodetool clhistogram foo_keyspace foo_table

CL    READ/WRITE
ANY 0/1
ONE 0/0
TWO 0/100
THREE 0/0
LOCAL_ONE 0/1000
LOCAL_QUORUM 1000/2000
QUORUM 0/1000
EACH_QUORUM 0/0 
ALL 0/0


Open to better layout or better separator, this is just off the top of my head.
