If I'm not wrong profiler requires a FG method server to run with a command: windchill --javaArgs=-Xmx512M wt.tools.profiler.WindchillProfiler. It doesn't matter if it's slave or master.
In the profiler you can filter for bgms if you want but only in case you started on that specific node. Are you on linux or windows? If linux do you have X11 forwarded?
