Re: [hobbit] Custom Graph Problem

["Dan Vande More" <bigdan (at) gmail.com>]

You gave us the first part of rrd dump, but you should also check to see
whether rrd has any data in it. Is the graph's png showing up, but showing
NaN? Is the graph not showing up at all?

It sounds silly, but try putting spaces in your output so it looks like
this:

order_gen : 19

It seems like I've had that issue before too. I have about 25 extra
tests I'm doing, and I use spaces in all of them.
