Alex Baranau commented on HBASE-2888:
-------------------------------------
qt. How would 3. differ from current log?
The difference is to have this shown somewhere in more user friendly-place e.g.
*on web interface*. The point I wanted to stress out is that currently
users/ops have to go for this information to the log files which isn't
straightforward for them (and leads to questions on ML as I linked to), I
think, but might be wrong.
Thanks.

> HBase publishes a bunch of metrics, some useful some wasteful, that should be
> improved to deliver a better ops experience. Examples:
> - Block cache hit ratio converges at some point and stops moving
> - fsReadLatency goes down when compactions are running
> - storefileIndexSizeMB is the exact same number once a system is serving
> production load
> We could use new metrics too.
