Subject metrics names
Date Tue, 10 Sep 2013 08:08:50 GMT

I've recently take a deeper look at the metrics in HBase and I was
wondering why some info ended up in the metric name rather than in tags for

For example I see metrics names like:


with tag 'hostName'.

Why not move 'tbl.-ROOT-.region.70236052' in two tags 'tbl' and 'region'
and have the simpler
'RegionServerDynamicsStatistics.writerequestcount' metric name instead?

Same thing for things like
'RegionServerDynamicStatistics.tbl.TABLE.cf.COLFAM.storeFileCount', tags
'tbl' and 'cf' would seem more logical to me.
