Sylvain Lebresne commented on CASSANDRA-7384:
---------------------------------------------

bq.  It's pretty common that a customer uses an incorrect consistency level for 
their environment.

I'll mention that this problem _might_ be better handled by CASSANDRA-8303.

Anyway, if we do expose counters for that (on which I'm neutral: I agree we 
can't expose everything but I understand that it could be convenient in some 
environment), we should also expose how often queries failed to achieve said 
consistency as suggested in CASSANDRA-9191 (I guess both might not be useful in 
the exact scenario but it feels silly not to just deal with them in the same 
patch).

> We had cases where cassandra client users thought that they were doing 
> queries at one consistency level but turned out to be not correct. It will be 
> good to collect metrics on number of queries done at various consistency 
> level on the server. See the equivalent JIRA on java driver:
