[Xymon] empty/broken extra graphs place holders 4.3.17

I found a similar posting that better describes my problem
<http://lists.xymon.com/archive/2012-March/034151.html>. Apparently it's a
well known issue with trends and mulitgraph. I removed the
TRENDS:*,disk:disk|iostat-disk|iostat-part from the hosts.cfg entry and
changed the GRAPHS= stanza in the xymonserver.cfg and added
iostat-disk,iostat-part after "disk"
GRAPHS="la,disk,iostat-disk,iostat-part
and now the broken iostat-disk and iostat-part graphs are gone, but the
some of the normal disk graphs still display broken/empty graphs due to
design of the mulitgraphs, i believe.
/*
* Some reports (disk) use the number of lines
as a rough measure for how many
* graphs to build.
* What we *really* should do was to scan the
RRD directory and count how many
* RRD database files are present matching
this service - but that is way too
* much overhead for something that might be
called on every status logged.
*/
Thanks
