Brandon Williams commented on CASSANDRA-12197:
----------------------------------------------
In nodetool we can just invoke sjk directly and it's done. For virtual tables
you'd have to programmatically manipulate the data into a virtual table format,
and then to use it you'd have to repeatedly query the table since ttop's values
constantly change over time.

> Assignee: Ekaterina Dimitrova
> Priority: Low
>
> SJK (https://github.com/aragozin/jvm-tools) has a command called ttop that
> displays the top threads within the JVM, sorted either by CPU utilization or
> heap allocation rate. When diagnosing garbage collection or high cpu
> utilization, this is very helpful information. It would be great if users
> can get this directly with nodetool without having to download something
> else. SJK is Apache 2.0 licensed so it might be possible leverage its code.
