Nagiosgraph Config

Hi All,

I have recently created a Nagios farm and have Nagiosgraph for trending.
After installing the new environment i have added a plugin for checking Memory. I have added the plugin in all clients and i am able to see the service in my Nagios Dashboard.
However i am not able to get the same in Nagiosgraph. Do i have to add something? I am under the impression that Nagiosgraph(1.4.4) will automatically read Nagios config file and graph them.
Please help if i am missing anything.

Thanks
HG
