Asaf Mesika commented on HBASE-7025:
------------------------------------
I'm running into a "too many hlog" warnings, which in turn causes (eventually)
region server to crash. I'm in the middle on analyzing it through the debug log
files and Graphite and could really use this metric to understand, overtime,
when started having a lot of wal files in the queue.
> Metric for how many WAL files a regionserver is carrying

> A metric that shows how many WAL files a regionserver is carrying at any one

> upper bounds and in need of attention
