From the top of my head: There is a flag to enable tracing every node that is executed in v2, as well as every file upload/download (in the fs/store/src/remote.rs) and every execution request (in process_execution/src/remote.rs), as well as metadata about remote-side timings that the execution server may have reported (e.g. in the scoot implementation, it reports time spent in remote queues, time spent for the worker to fetch input files, time spent for the worker to upload output files, etc)
