Graph interfaces traffic

[rourou]

Hello,

I'm trying for a few day to graph localhost interfaces trafic...

I've created my device and associated the corresponding data query (interface traffic)
but when I go to the graph view section, the graph are not displayed and I've got only the tittle of the 3 graph (eth0, sit0, lo) corresponding to my 3 interfaces... nothing else...

What should I do ?

I try to execute ##> php /var/www/html/cacti/cacti-0.8.6c/poller.php

Here is the result :
ERROR: Duplicate DS name: traffic_in
OK u:0.01 s:0.01 r:2.13

I don't know what to do.

Thanks for your help

I'm seeing nearly the exact same thing on version 0.86d trying to graph eth0 and eth1. Here are the errors, everything else is successful.

ERROR: Duplicate DS name: traffic_out

Edit data template "Interface-Traffic"
In and out must have a unique name. If you have in + in max +out +out max please don't use names like: in + in +out +out This doesn't work

If you open the Template, you see 4 tabs.
click on each tab an rename them with unique names (you need only to rename 2).

After you did this, the new rrd-file will be saved and you'll get your graph.
This belongs to every Debian Sarge user, too, due to a bad Template in the packet.

As I found out earlier
You have the Duplicate DS Bug....
