You can run JConsole on your workstation and connect remotely to the nodes, it does not need
to be run on the node itself. Connecting is discussed here and
some help for connecting is here

There is also a Web front end for the JMX service

And a recent discussion on different way to monitor a node If
you did through there is some talk about a JMX<>REST bridge. 

Hope that helps.

Thanks Aaron. As I remarked earlier (and it seems it not uncommon) none of
the nodes have X11 installed (I think I could arrange this, but it's a bit
of a hassle). So if I understand correctly, jconsole is a X11 app, and I'm
out of luck with that.

I would agree with you that having a proper nodetool command to zap the data
you know you don't need, would be quite ideal. The reason I'm so retentive
about it is that I plan to test scaling up to 250 million rows, and disk
space matters.
