Please help on MRTG ...

I tried to monitor cpu usage, and I use cpuinfo.pl from mrtg-2 contrib directory, when I run it I got this error on the console :

Host key verification failed.
WARNING: Problem with External get '/home/www/mydomain.com/cgi-bin/mrtg/cpuinfo.pl myhost.homelinux.net linux':
Expected a Number for 'in' but got ''

WARNING: Problem with Externale get '/home/www/mydomain.com/cgi-bin/mrtg/cpuinfo.pl myhost.homelinux.net linux':

ERROR: Target[127.0.0.1_myhost][_OUT_] ' $target->[0]{$mode} ' did not eval into defined data

and here is my mrtg.cfg :

Target[127.0.0.1_myhost]: `/home/www/mydomain.com/cgi-bin/mrtg/cpuinfo.pl myhost.homelinux.net linux`
MaxBytes[127.0.0.1_myhost]: 100

PageTop[127.0.0.1_myhost]: <H1>CPU usage for myhost
</H1>
<TABLE>
<TR><TD>System:</TD><TD>myhost</TD></TR>
</TABLE>

Anyone can give me any help? how to make this work ...
