Hi,

I'm trying to add more information to samples collected by OpenStack. I know for events I can modify the event_definition.yaml file but for notifications I'm not quite sure how to do it.

Let's say for example I've got two different interfaces on a VM, and I want to see the bandwidth consumption of each one, how should I do it? I've been trying to correlate the information stored in the metrics, but I cannot really find a way to correlate them, as I'm missing some information in the samples collected by ceilometer.

Thanks!
