I think the rationale of the counter aggregation needs to be explained. My understanding is that the metering system will be able to deliver the following information: 10 floating IPv4 addresses were allocated to the tenant during three months and were leased from provider NNN. From this, the billing system could add a line to the invoice : 10 IPv4, $N each = $10xN because it has been configured to invoice each IPv4 leased from provider NNN for $N.

It is not the purpose of the metering system to display each IPv4 used, therefore it only exposes the aggregated information. The counters define how the information should be aggregated. If the idea was to expose each resource usage individually, defining counters would be meaningless as they would duplicate the activity log from each OpenStack component.

What do you think ?

Cheers
