Capturing a threadgroup's end of execution

[vincent . lortie]

Hello,

I was wondering if there was a way in JMeter to identify when all the 
threads of a given ThreadGroup have finished executing (a bit like 
implementing the TestListener interface allows you to know when an entire 
test ends). If there is no straightforward way of doing this is there a 
circuitous way?

Thanks in advance,
Vince
