Hi Volker,

In your situation, it sounds like it would be best to generate the
graphs on the systems where the data are collected. You might consider
some combination of

- Store the graphs in an NFS-mounted file system so that
  they will be readily available to the system that generates
  the reports
- Set up a mini-rrd server (I'd use Perl/cgi) that responds to
  specific requests, and either returns the graph image or a
  pointer to a file on a shared file system.
