Hi,
thanks for the quick reply.
You'll probably want to check your httpd error logs for the showgraph.sh/.cgi execution and see if there's anything unusual happening. The RRD graphs are generated on the fly, so this would point to a live error there.
Nothing there but a few "sendto failed" lines
2016-11-03 17:18:11.401220 Sendto failed: No buffer space available
which are probably due to unreachable clients.
Are you getting blank loads or actual broken images?
Blank loads - they have appropriate y/t axis and legend, but never any data.
Another option would be to add "--debug" to CGI_SHOWGRAPH_OPTS in /etc/xymon/cgioptions.cfg.
This gives me

-- This is probably unrelated, but xymond.log has a repeated

when there is no machine called 'i386'. There is one xymonclient on an OmniOS (solaris) machine, whose
% uname -a SunOS Venediger 5.11 omnios-r151018-258cc99 i86pc i386 i86pc %
has i386 - maybe the client picks the wrong field. But, as I said, probably not related to the blank graphs. Still searching for a clue...
Cheerio, hauke
