Toshihiro Suzuki commented on HBASE-11062: ------------------------------------------ I removed the dependency for Lanterna to remove the license problem. And I created a new PR: https://github.com/apache/hbase/pull/476 > hbtop > ----- > > 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. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
