> 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.
