[Xymon] graph themes

28 Nov 2018 · *invalid color def format*

      Individual line colors are listed in xymon/server/etc/graphs.cfg.  E.g. the
clock graph line is 00CC00 (mostly green):
[clock]
TITLE Clock offset
YAXIS Seconds
DEF:offset=clock.rrd:la:AVERAGE
LINE2:offset#00CC00:Seconds
^^^
The default colors for the @RRDIDX@ multi line graphs are set in
xymon-4.3.28/web/showgraph.c:
 char *colorlist[] = {
         "0000FF", "FF0000", "00CC00", "FF00FF",
         "555555", "880000", "000088", "008800",
         "008888", "888888", "880088", "FFFF00",
         "888800", "00FFFF", "00FF00", "AA8800",
         "AAAAAA", "DD8833", "DDCC33", "8888FF",
         "5555AA", "B428D3", "FF5555", "DDDDDD",
         "AAFFAA", "AAFFFF", "FFAAFF", "FFAA55",
         "55AAFF", "AA55FF",
         NULL
 };
You'd need to recompile showgraph.cgi to change those.  I don't know if
there's any place to change those without a recompile.

Just to close the loop on this conversation, here's what I added to my
xymonserver.cfg file to get my graphs the way I wanted.  As previously
stated the opts are all on one long line.

I'd still like rounded corners and I haven't figured out how to change the
graph line colors, but that's not a big deal for me at this moment.

There may be a better place to put this, but it works for me.  In:
 /home/xymon/server/etc/xymonserver.cfg
add this as one long line:
RRDGRAPHOPTS="-c BACK#363636 -c CANVAS#000000 -c SHADEA#CFCFCF -c

Take them out of the graphs.cfg file.  I don't know if it's strictly
necessary to restart Xymon, but I did, and all the graphs now come up with
those colors.  Not sure how to make it work with individual graphs.

I tried adding the color lines into my graphs.cfg file as specified in
this how-to
https://oss.oetiker.ch/rrdtool/doc/rrdgraph.en.html
I edited one section to see what would happen.  It threw an error that
said *invalid color def format*
Here's the section of my graphs.cfg that I edited.  Anyone know what the
correct formatting is so I can stylize my graphs?

Something similar to Grafana would be awesome! It provides a very rich
set of graphing options.  (see image below) No idea if RRDs can be used
though.

Can anyone advise on how to theme the graphs a bit?  After 20 years of
the light gray rectangles I'd like them to look a little more modern.
