Package com.codename1.backend.otel

package com.codename1.backend.otel

OpenTelemetry tracing and metrics for a backend, exported over OTLP/HTTP without an OpenTelemetry library.

Most servers never name these classes: the OpenTelemetry annotation in com.codename1.backend.annotations has the build wire an OtlpTracer into the generated entry point. Code that assembles its own server installs one with com.codename1.backend.Tracing.install, and every request, outbound call and database statement is then exported as a span to the collector the deployment names. OtlpMetricExporter sends the process's metrics to the same collector on an interval.

Server code: this package is not available in the app.
