Comment 4 for bug 1188218

I have a problem with the wording of the bug report: "we will need an agent which runs inside each baremetal instance".

Baremetal (and Ironic) instances do not, by definition, necessarily have an agent.

That said, gathering counter data *might* be possible via IPMI calls remotely, in some situations, but no code has been written today to do that.

Providing information such as duration and size of an instance could be accomplished fairly easily via an agent alongside (or a hook inside) nova-compute and ironic-conductor.
