Most of the comments on this thread are talking about using OpenTelemetry to send metrics/logs to self-hosted collector jobs. Though using a standard library supported by a bunch of collector tools like ClickHouse is useful it itself, there's another benefit too. The specification allows transferring trace IDs across system boundaries. If you and your dependencies all implement the OpenTelemetry spec, then you get spans that reveal in granular detail what happened in the journey. For example, you could learn that it was your database loading a page from disk that took so long, or that a Cloud service's metadata plane was the responsible span for high latency.
