I'd really like being able to see that information in that place, but it
is not possible by now.

The problem while viewing crm_mon, for me, is mostly that the output
does not fit on my screen or I have to reduce text size so much that I'd
need binoculars. This pingd output would cause even more lines. So it
should at least be optional, if you are planning to implement that.
