graph empty and rrd file with NaN values

[keneda95]

Hi everyone,

I create data input methods (check_apachestatus.pl), graph template and data template.
When I check on command line ./check_apachestatus_ssl_2009.pl -H 172.20.x.x I can get values but the cacti graph is empty with Nan values.
I checked user rights and it looks OK.

Is it possible a plugin cannot generate values on rrd files ?
Please can you help me ?
