Try running NM like:

NM_PPP_DEBUG=1 /usr/sbin/NetworkManager --no-daemon

to get more debugging output from pppoe.

NM is actually always in debug mode, there isn't granular enough logging
here to do what you suggest (yet).  There's a bug for this, and its
certainly something that needs to be implemented.
