I figured that out from your previous mail - that you've been using a
GAUGE RRD file, whereas the linecount function uses a DERIVE file.

In fact, since the GAUGE/DERIVE setting is only used when the RRD file
is created, you could - as a workaround - create the RRD file by hand,
and then just use the current linecount function to update it. That
would work, I think.

Several nice ideas here; the ability to track absolute linecounts is
reasonable, and having a way of configuring what graphs go on what
status columns has been discussed before - it is definitely one of
those things that really need improvement. And I think it would be a
good idea to create status columns from any RRD data item that we have,
which would solve your last point.

Thanks, but it's a long journey. Each time we get a little closer,
though.
