[Nav2][Discussion] Metrics / framework for quantitative evaluation of navigation performance

Yeap, you’re right @smac, @Pepis’s probably more interested in functional benchmarking data, but that can also be enabled with our approach described above and that’s the point that I wanted to make:

With a bit of effort I believe we can actually make these topics related and consistent (and hopefully re-usable across ROS stacks). @christophebedard did a good work creating a data model that could be used to determine functional aspects a posteriori (after the computational graph has run, using the trace data). I think btw this is a good complement to the tools you linked above and believe it’d be interesting to compare the same benchmarks. Happy to partner up on this!
