I'll post here this script, and explain more what are running here.

?>Let's go...
This is a PHP script, just need a Data Input Method, Data Source and the Graph to get its working, right...
In this script on pageload-agent.php return 5 parameters (con, dns, ttl, str, pre), when it is runing on command line, allways return all parameters.... but when its runing on Cacti, it return sometimes all parameters... but almost all polling just return the parameter "dns".
So, on graph I have gaps just in some parameters, and DNS allways work. I'll atach a ss to check waht I m talking about.
What can be the reason of this problem? I made all step by step, I've checked all points... and its allright... Well this script can be very usefull if works.
The blog where I found this script is:

Hope someone can understand this problem and help me.
Thx!
