X11 status Capture for an arbitary application

The window-specific attributes? You can look at the X window properties,
using a tool like xprop, but that may not be what you want.

Events are delivered over a socket. It's up to the client to determine what
to do with the data retrieved from it. The client may leave unhandled
events as raw data waiting in the socket's buffer, or it may parse them and
put them on its own event queue. Knowing this requires knowing how the
internal application was developed, which you have no knowledge of without
the application's source code.

I'm not sure how knowing "menu lists" (which, as Alan said, has no native
support in the X protocol) would help you build a resource monitor. What's
the use case you have?
