Josh Elser commented on PHOENIX-3807:
-------------------------------------

I've just hacked something together (albeit, on an ancient version) that will do call time histograms and slow call counters. Will try to rebase that on master and put it up.

> Add server level metrics for secondary indexes
> - Histogram metrics for time to complete all secondary index updates per primary table update per index type. Will help us trend perf over time and catch impending issues. 
> - Histogram metrics for number of updates dispatched to secondary index stores to service one primary table update per index type. Will help us catch inefficient behavior or problematic schema design. 
> - Count of deployed secondary indexes by type. Will help understand and trend index usage, or catch deploy of an unwanted index type.
