Summary: Add histograms of key attributes to server front pages
Key: HBASE-11688
URL: https://issues.apache.org/jira/browse/HBASE-11688
Project: HBase
Issue Type: Improvement
Reporter: stack
Priority: Minor
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?"
