[Xymon] Xymon installation comes up with empty graphs

[Hauke Fath]

Hi,

a xymon 4.3.27 installation I set up a while back generally works, but 
comes up with all blank graphs.

The setup basically consists of additions to hosts.cfg.

The host .rrd files are non-empty according to 'rrdtool info ...', and 
manually producing .png graph files after 
<http://lists.xymon.com/archive/2010-September/029443.html> results in 
plausible, non-blank graphs.

Where do I go next?

Cheerio,
hauke
