Subject [jira] [Commented] (HBASE-7025) Metric for how many WAL files a regionserver is carrying
Date Mon, 11 Nov 2013 23:04:18 GMT

stack commented on HBASE-7025:
------------------------------

This looks like a good idea.  Count of WALs impinges on MTTR too so would be good being able
to graph this over time.

> A metric that shows how many WAL files a regionserver is carrying at any one time would
be useful for fingering those servers that are always over the upper bounds and in need of
attention
