There was a problem hiding this comment.
We should change this whole section so that:
- it is not Jaeger specific. No need to mention
JAEGER_TRACEat all. Just OpenTelemetry - Keep the Jaeger-all-in-one example but just use the OTEL envs
- No need to document separate options for grpc/http. Users can find that from OTEL docs.
- Can keep the mention of other OTEL backends. If you tested a specific one then you can provide a quick example.

Adds documentation for OTLP trace export configuration to the OpenTelemetry section of the README.

OTEL_TRACES_EXPORTER=otlpenvironment variable documentationRelated Issue
Closes #4001
The current OpenTelemetry section only documents Jaeger trace capture via
JAEGER_TRACE. This PR adds OTLP exporter documentation, which is the standard protocol supported by OpenTelemetry and allows sending traces to any OTLP-compatible backend.
