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.
