Instrumentation has been merged into the ROSS master branch. It has been tested and works without requiring any changes to CODES, however, in order for the event tracing feature to collect event type information, some additions have to be made to the LPs. I've made the appropriate changes for some of the LPs (dragonfly router, terminal, synthetic workload LP, and model net base LP).
There's a README-vis.md that explains some CODES specific details regarding the instrumentation. There's also a blog post on the ROSS website that explains how to use the various instrumentation modes.
