That's the rub that I think you are missing. In distributed and/or cloud environments it is quite unusual for there to be a single end-to-end process, and thus we need new ways to trace across a system.

In harmony with tracing, we also need the aggregated view _across_ the estate to understand where system hotspots, levels of throughput, redundant infrastructure, error rates, etc.
