Comment 14 for bug 1518338

I'm looking at this kind of things, i'll write up an email to discuss in details. Basically speaking, the snmp related metrics encounter the same problem as the instance metric disk.device.*, as both of these adds 'suffix' to its resource_id.

Maybe we should create new types of resource in gnocchi here for snmp metrics.

As for using the same resource_id for all metrics for different disk/interface within an VM instance/machine, I'll write up an email to discuss this
