  OpenTelemetry Go API and SDK

  

To send traces to the monitoring system, we need to use some framework. OpenTelemetry is a standardized and recommended approach to implementing tracing in the application nowadays. It gets support from all popular tools so the integration will be seamless.

• Elasticsearch
