Thanks Jay for pointing this out.
Adnan,
Yeah - you could use PcP - if that module gets integrated with Nova.
For your benefit, here are some of the metrics that PcP can provide
related to the physical NIC:
pminfo | grep network.interface <== Listing the available metrics.
network.interface.collisions
network.interface.mtu
network.interface.speed
network.interface.baudrate
network.interface.duplex
network.interface.up
network.interface.running
network.interface.inet_addr
network.interface.ipv6_addr
network.interface.ipv6_scope
network.interface.hw_addr
network.interface.in.bytes
network.interface.in.packets
network.interface.in.errors
network.interface.in.drops
network.interface.in.fifo
network.interface.in.frame
network.interface.in.compressed
network.interface.in.mcasts
network.interface.out.bytes
network.interface.out.packets
network.interface.out.errors
network.interface.out.drops
network.interface.out.fifo
network.interface.out.carrier
network.interface.out.compressed
network.interface.total.bytes
network.interface.total.packets
network.interface.total.errors
network.interface.total.drops
network.interface.total.mcasts
# pmval network.interface.out.bytes <== A sample metric value.
metric: network.interface.out.bytes
host: <my_host>
semantics: cumulative counter (converting to rate)
units: byte (converting to byte / sec)
samples: all

As you might observe, there's a plenty for you to draw inferences.
Hope this helps!

I am writing a nova filter that will check for the compute node (max,

recommended tools that can provide this info in real time? Does any
openstack component hold this info already?
You may want to chat with Sudipta Biswas (cc'd). The PCP module (yes,
it's an awkward name for a performance profiling module...) does some
of what you're looking for and Sudipta has been attempting to
integrate it with Nova for this express purpose.
Best,
