> 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
> Fix For: 3.0.0, 2.3.0, 2.1.7, 2.2.2
>
> Attachments: HBASE-11062-master-addendum-v1.patch
>
>
> 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.
