title: how can I log the current threadcount in SOAPUI?
body: <p>I need to create a log file from a SOAPUI load test that shows the threadcount at 1-second intervals.  The file needs only a timestamp and the threadcount, and can be CSV or any other format really.  I can't see a way to get just this info from the predefined log files.</p>
  
  <p>Is a Groovy script step the right way to do this?  How would I write it?  I could have a test case that does nothing but writes the log message every second while the "real" cases are running concurrently, but I don't know how to write that simple bit of script.  I find the documentation almost impenetrable.</p>
  
  <p>Thanks in advance!</p>
