I don?t think the rrd file is working right.
It is there, and the latest numbers are in, but I don?t see any
archive numbers populating.
Where can I check for that?

Could be wrong, but I think the graphs need two or three data points
in order to show anything.

Looking in the rrd file, it doesn't seem like there are the
historical data in the file.
The data is only going to change once a day, so I was only calling
the script once a day.
I'm going to run the xymon script every hour to see if that gets
the pump primed, and give me more data.
Does the graphing thing need more frequent data?

No difference.
I didn't restart xymon for that, just removed the --no-cache from
the lines in tasks.cfg , and killed the rrd processes.

Hmm.
That's definitely odd, but if at least some of the graphs are showing
then it's not an overall systemic issue. Have you tried removing the
--no-cache from the RRD calls by any chance?

Selinux is set to permissive.
Most graphs are working for other tests. Some complicated ones
with variable data points. I didn't set those up, but they are
working well.

This is probably a sign of invalid rrdctl socket files, as
that's what
showgraph is trying to use to communicate with xymond_rrd.
These should be in the TMP/RUN dir on a source compile, named
"rrdctl.<pid>", one for each of the currently running xymond_rrd
processes (usually two,m one for status, one for data). They'll
need to
be writable by your apache user at least, and SELinux may require
additional permissions for the sendto if you have it enabled and
enforcing. If you see lots of stale ones, be sure to remove them
-- as
showgraph.sh doesn't know what's current, I believe it tries to
cycle
through all of them, which could end up in timeouts.
Regardless, premature header ending isn't a desired result no matter
what the situation. Trying to find all cases of this is a longer
term
goal for all the CGIs.

And just to confirm, the file does actually existing in the RRD

Any help?
Then there is a problem generating the RRD, the error is
returned as
text. But you browser expects a graph, not some text so it
displays a
broken image symbol.
When yoy right click on one of the broken image, you can say
'open image
in new tab'.
This will give you the direct URL of the graph.
If you do a wget of this URL (don't forget quotes!) on your xymon
server, you will download the real error.
Just do a vi of the downloaded file to see this error.
