Andrew Purtell created HBASE-11062:
--------------------------------------
Summary: htop
Key: HBASE-11062
URL: https://issues.apache.org/jira/browse/HBASE-11062
Project: HBase
Issue Type: New Feature
Reporter: Andrew Purtell
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.
