Robert Coli commented on CASSANDRA-10323:
-----------------------------------------

{quote}Is taking the attempted replicas - successful replicas work for that? 
Can make a gauge to make it easier{quote}
That's a measure of how many retries you've ever had, not a measure of how many 
retries are in the queue now, isn't it? To me the latter is more valuable than 
the former.

> Add more MaterializedView metrics

> We need to add more metrics to help understand where time is spent in 
> materialized view writes. We currently track the ratio of async base -> view 
> mutations that fail.
> We should also add
>   * The amount of time spent waiting for the partition lock (contention)
>   * The amount of time spent reading data 
> Any others?
