Ask HN: Is OpenTelemetry ready for production use?

Check out OpenTelemetry: https://opentelemetry.io/ https://opentelemetry.io/ > OpenTelemetry is in beta across several languages and is suitable for use. We anticipate general availability soon. Can folks share their early experience with Open Telemetry? Specifically, how are the integrations for major runtimes like Java and Node, when compared with, say, the fairly mature commercial integrations of New Relic?
