> Project: HBase

> Priority: Minor
> Labels: beginner

> Messing with histograms of late, seems a pity we don't show in UI histograms
> of basic recent events and metrics. In past we've tried to keep history in a
> history table and we've talked of bringing this back as data source for being
> able to mine what has been happening of late and in the recent past but
> meantime, we could keep running in-memory histograms of recent history and
> show cute little histo-diagrams of hits, compactions, flushes... Would be
> nice little project with a high profile. It'd not be a replacement for
> cluster monitoring but more just an at-a-glance high-level dashboard that
> gives a clue on "...what has my cluster been up to of late?"
