I really love this template -

however I can't figure out where to specify an interface

I go into datasources, selected data template interface - traffic

name: |host_description| - Traffic Port 2/7

then I'm assuming index value box is where I enter numbers such as 2/7? under the custom data

I'm in the exact same boat, I thought it was permissions no rra files are being created I'm using the poller.php also, cron script same I can see the under the poller cache that it's getting snmp stuff (cisco 6506) but it never saves them to rra databases. is it because I'm using rrdtool-1.0.46-32.1?
