Kolo.app for Django and Observing Pythons - Talk Python to Me Ep.464

With all this tracing thing it sounds like you reinventing OpenTelemetry tracing. We have it on in production for getting insights on the execution paths, timings and parameters. For any span you can add any meta (user name, id etc for instance), you can enable auto-instrumentation for requests, SQL database queries, external requests and much more. And all of that is free and with great support from CNCF. Grafana, Zipkin, Jaeger all work with it.
