Hello evilmercer.
I guess you can configure ipfix and use 'show ip ipfix' commands to see the individual pathway.
May be ipfix will help you.
For example - the sho ip ipfix commands output from slot 1 of the ERS8606 (7.2.12.1) in lab environment:
R1:6# sho ip ipfix flows 1

This is last release, but in my opinion, it will works the same in your release version.
