stack commented on HBASE-11062:
-------------------------------
The animation showing how hbtop will look in the README is sweet. The README
itself is really helpful. Add pointer to it up in the release notes for this
issue? Should the README get integrated into the refguide, perhaps as a
follow-on?

> Key: HBASE-11062
> URL: https://issues.apache.org/jira/browse/HBASE-11062
> Project: HBase
> Issue Type: New Feature
> Components: hbtop
> Reporter: Andrew Purtell
> Assignee: Toshihiro Suzuki
> Priority: Major
>
> A top-like monitor could be useful for testing, debugging, operations of
> clusters of moderate size, and possibly for diagnosing issues in large
> clusters.
> Consider a curses interface like the one presented by atop
> (http://www.atoptool.nl/images/screenshots/genericw.png) - with aggregate
> metrics collected over a monitoring interval in the upper portion of the
> pane, and a listing of discrete measurements sorted and filtered by various
> criteria in the bottom part of the pane. One might imagine a cluster overview
> with cluster aggregate metrics above and a list of regionservers sorted by
> utilization below; and a regionserver view with process metrics above and a
> list of metrics by operation type below, or a list of client connections, or
> a list of threads, sorted by utilization, throughput, or latency.
> Generically 'htop' is taken but would be distinctive in the HBase context, a
> utility org.apache.hadoop.hbase.HTop
> No need necessarily for a curses interface. Could be an external monitor with
> a web front end as has been discussed before. I do like the idea of a process
> that runs in a terminal because I interact with dev and test HBase clusters
> exclusively by SSH.
> UPDATE:
> The tool name is changed from htop to hbtop.
