I'm only aware of Sflow being IP/protocol/etc aware.

Actually the sflow standard is flexible, and there are many fields widely available, including input interface and 
output interface, vlan/vxlan/mpls headers, etc. The sending device just needs to support the fields.

To give you an idea of some of the fields you can query from a TS server for example, here’s a description of one of 
the tables in the database: https://inmon.com/sentinel_help/8.0/help/en/report/api_view_traffic.shtml

Browse sflow.org for more fun info, including ideas for running sflow agents on your hypervisors (for eg correlating 
CPU and RAM usage per VM) etc :-)
