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

OK, check_icmp looks good.

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,
