I have uploaded the frames -screen capture (as PDF upload is not allowed).

I am getting the same issue as mentioned in the original question. The "unknown_publisher" is evident in the tf_monitor, but the view_frames seems to capture the frames nicely in the pdf output (which is attached as image)

rosrun tf tf_monitor:
