Sorry, yeah I was a bit unclear. I was curious if there was any metrics to show how maybe server CPU/Memory or client-side latency changed after moving your app to Rust and running for a year. But that's fair, if adding open-telemetry is maybe overkill to add to the application it might not apply as much to your use-case.
