Brandon Williams commented on CASSANDRA-12197:
----------------------------------------------

So much +1 on this.  I've had to ask people to install sjk so many times to 
troubleshoot something I've lost count.  Excellent tool that we should 
integrate.

> 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.
