Newbie - help needed - Interface mapping

[ibby]

Hi guys,

I have managed to install a cacti server on cents and its running ok.

I have been taking templates from the site and using them for the SRX/J series routers.

I am trying to map/graph my interfaces and I cant seem to get my head around getting it working.

What steps do I need to take for it to work ?
eg
Import the template.
set up the data source?
setup the graph.

HELP

Thanks
