It is a result of how the NCV handler in hobbitd_rrd expects data to
be formatted, so yes - this is hobbit specific.

I've updated the hobbitd_rrd man page and added this to the section on
how to use the NCV data:

  Note that each "NAME : value" must be on a line by itself. If you have
  a custom script generating the status- or data-message that is fed
  into the NCV handler, make sure it inserts a newline before each
  of the data-items you want to track.

That should hopefully make it clearer - I'm sorry it bit you.

Agreed - did that as well.

Fixed :-)

Thank you for reporting what you found - that is the kind of feedback
I need to make Hobbit better.
