The srv-pnp and host-pnp templates will set the process_perf_data
directive like so:

  process_perf_data   1

If you override this by setting process_perf_data to 0 in the host or
service definition, this will stop PNP from generating the graph!

I recommend you remove the line which says "process_perf_data 0" from
those service and host definitions in "mynet.cfg" which use the
srv-pnp and host-pnp template.

I hope that helps,

Jim
