Yes OpenTelemetry is awesome in what it's done for the industry - it was really early when I was still at Mezmo/LogDNA but it's matured a lot, though I think still has a ways more to go.

For automatic logging - I think you'd enjoy OpenTelemetry's automatic tracing implementation, it helps pull out standard telemetry from things like your Redis requests and correlate them with trace IDs so you can tie everything together from the moment your server starts accepting the HTTP request to the Redis and DB requests and what was sent in each request (without needing to do it manually)

For capturing HTTP req/res - we actually have a few options depending on the language (ex. we do this for Python and Node.js) to enable more advanced network capture (so you can actually get the full req/res information, or whatever subset you're interested in actually storing)! It's actually been asked by a number of teams to make it easier to debug tricky API issues they're running into.

Proper end-to-end logging definitely makes it easier to find the right clue among a sea of logs, hopefully we make it easier to get there!
