[Xymon] Process change

Okay, in answer to my own question, I finally found, or so I thought, a way to add my client data to the Xymon clientdata, but how do I get it to show up under a specific section? If I provide a TESTNAME, it ends up under a different collector id - [collector id: mytest]. If I make TESTNAME blank, it doesn't show up at all!

Thanks, ​ David
