[hobbit] Custom graphs: RRD database won't populate

[Haertig, David F (Dave)]

Thanks for the reply.  Unfortunately, I've already been through that
documentation over and over.

But I think I stumbled onto the answer by just blindly guessing and
changing things around.

I changed my custom script to send in "green" status messages rather
than "clear", and what do you know, an RRD datafile was created.

My custom script was sending in data with an indication of "clear".
This is what I normally use for tests I'm working on that are sending
data, but I haven't applied any red/yellow condition checking yet.
i.e., This is my way of saying "Here's some raw data to view on a web
page, but without any interpretation applied to it yet".  I can't
remember what the original intent of "clear" was, I stole that color for
my own use years ago when I started with Big Brother.  I imagine Hobbit
was applying the original meaning of "clear", whatever it was, and
therefore not moving the data to an RRD file.    Maybe this hobbit
operation is by design, and that's fine with me, ... it would be nice if
the documentation on how to create custom graphs mentioned it however.

Thanks!
