Hi Simon, 
  thank you for the immediate response!
  Well, now the link shall work - i have opened my firewall ;-)
  I also attached the graphs created (rejected by the list admin because of mail size, so look at the web site http://hk1.famenzel.at/cgi/hk1.cgi <http://hk1.famenzel.at/cgi/hk1.cgi>).
  Here is the setup script:
  rrdtool create AgroFire.rrd --step 1 \

  The values are written with this
  CommandString=  rrdupdate /path/AgroFire.rrd 1433965266:20:0:20:25:23.8:25.9:0.0:72:25.3:0.0:70:0:0:5:0:1024:0:0:0:0:113:61134:7
  every second to the RRD.
  I have also attached the cgi-script:
  Hence the graphs are all generated the same way I wonder why the once for the month and the year show this errors.
  I guess the data are ok because the daily and weekly graphs are ok.
  Thank you for any hint on this problem.
