Hi Lynn,
just add ad the beginning of your show.cgi the following line (you may
change the colors in this line):
my @colors = qw ( FF0000 00FF00 0000FF FF00FF FFFF00 00FFFF FFFFFF ) ;
in the subroutine rrdline, there are some minor changes aswell:
sub rrdline {
my($host,$service,$geom,$rrdopts,$G,$time) = @_;
my($g,$f,$v,$c, at ds);
@ds = ('-', '-a', 'PNG', '--start', "-$time");
# Identify where to pull data from and what to call it
for $g ( @$G ) {
$f = $g->{file};
debug(5, "CGI file=$f");
my $index=0;
for $v ( sort keys %{ $g->{line} } ) {
# $c = hashcolor($v);
$c = $colors[$index%(@colors)];
debug(5, "CGI file=$f line=$v color=$c index=".$index%(@colors));
my $sv = "$v";
push @ds , "DEF:$sv=$Config{rrddir}/$f:$v:AVERAGE"
, "LINE1:${sv}#$c:$sv"
, "GPRINT:$sv:MAX:Max\\: %6.2lf%s"
, "GPRINT:$sv:AVERAGE:Avg\\: %6.2lf%s"
, "GPRINT:$sv:MIN:Min\\: %6.2lf%s"
, "GPRINT:$sv:LAST:Cur\\: %6.2lf%s\\n"
;
$index++;
}
}
Regards,
Peter
