[FR] Add interface "name" to labels?

[emiljoensson]

Is it possible to have labels, such as ovs_interface_tx_packets, to also include the "name" and not just "uuid"?

Reason is that uuid may change at any time (e.g KVM VM is edited/redefined), but the name can be used as unique and persistent identifier.

Just to be clear, with name I mean this field:
ovs-vsctl -- --columns=name,_uuid list Interface

Thank you!!

@emiljoensson , yes. It is done in this fashion.

It uses Transact() function:

Hi, I was using this exporter quite successfully, so thanks for your work!
Because of the way I was using it, I was also missing a feature where I can query statistics by interface name directly. Of course you can work it around in prometheus by using joins but direct access it much easier. I have added simple PR that is adding interface name label to each metric related to interface statistics.
Thanks
