You can do something like
[root at nagios log]# > srvperf.log

or on perl planet

    open(FP, ">$log") ;
    close(FP) ;

Hier, i don't agree with you... if you have 2000 services...

I have a perl script which read nagios cfg, get 
xpdfile_service_perfdata_file and generate rrd command
(use | var=val and support nsclient check_disk and check_cpu)
