A bit of digging around brings this up:

This is a real shame. We have a paid up license of JProbe here but I have 
been playing with Hyades and found it to more robust for profiling under a 
heavy load.

I have also been playing with the Netbeans Profiler (formally JFluid) 
which looks promising but is at a very early stage of development. The 
other downside is having to use Netbeans!

I can't understand why Hyades offers some really powerful features as open 
source while missing this basic function of a profiler.

Maybe it won't be so difficult to write a plugin to present this view.
