You might find D-feet useful: https://fedorahosted.org/d-feet/

It is a DBus debugger that you can use to see what applications have
listeners active, what APIs are supported, etc.

I asked some time ago whether there was
(a) a way to self-document DBus APIs when registering them (as you can
do with the GIMP in plug-ins, for example) or
(b) a way to inspect DBus and get something resembling API docs out of
it, or
(c) some gtk-doc or Doxygen convention we could use to document D-Bus APIs

I was told "no" for a and c, and D-feet, dbus-monitor (which David
mentioned in that tools wiki page) and dbus-inspector
(http://www.vitavonni.de/projekte/dbus-inspector.html.en) are the best I
could find.

Cheers,
Dave.
