Do you use regular host checks with Nagios 2.x ? Tis is not the best

Is "process_perf_data 1" set in your service definition or templates ?

Thats OK. PNP dont need this file if your using the PNP Default Mode.

First choose the right mode for your installation.
http://www.pnp4nagios.org/pnp/modes
Configure PNP based on http://www.pnp4nagios.org/pnp/config
and check the function as described on
http://www.pnp4nagios.org/pnp/verify
Kind regards,
Jörg
