Hi all,

I am trying to get Apache RRD graphing work i xymon 4.3.0, but it looks like
apache.rrd is not updated with data.
I have verified that example.com/server-status?auto returns info, but
according to "rrddump dump apache.rrd", only values I can see are NaN.

According/var/log/xymon/rrd-data.log  (xymond_rrd with --debug option),

Any ideas how to debug this further?
