Maybe you should comment this one (above) out.

Look at the log file, which should be defined using the "log_file"
directive together wth the "log_level" in /etc/nagios/ngraph.cfg,
or wherever you keep the NagiosGrapher configuration file.

I have the following, which gives loads of info in the log:

  log_file             /var/lib/nagios/grapher.log
  log_level            1023
