I'm writing a simple post-mortem profiling tool that provides some of the information that you are looking for.  That being said, the tool, Loba, isn't publicly available just yet.  In the mean time, take a look at mpiP (http://mpip.sourceforge.net/).

You are correct. A real time tool would be best that sniffs at the MPI
traffic. Post mortem profilers would be the next best option I assume.
I was trying to compile MPE but gave up. Too many errors. Trying to
decide if I should prod on or look at another tool.
