Covers configuring a CLI with clap for verbosity/log-format options, composing tracing subscriber layers with EnvFilter, wrapping eyre::Report for use as Axum responses, decorating routes with #[tracing::instrument], and using TraceLayer with custom span functions. Includes examples of filtering logs by crate, URL, or span field, and notes a path toward OpenTelemetry integration as projects mature. ## Full article daily.dev links to this article rather than hosting it.
