To configure OpenTelemetry resource attributes, specifically service.namespace and service.name, follow one of the methods below. These attributes are crucial for identifying your services within OpenTelemetry.

• System Property: When launching your application, set the otel.resource.attributes system property:

  -Dotel.resource.attributes="service.name=myServiceName,service.namespace=myServiceNamespace"
  

• Environment Variable: Define the OTEL_RESOURCE_ATTRIBUTES environment variable in your environment:

  export OTEL_RESOURCE_ATTRIBUTES="service.name=myServiceName,service.namespace=myServiceNamespace"
  

• OpenTelemetry Collector Configuration: If you are utilizing an OpenTelemetry Collector, you can specify the service.namespace and service.name resource attributes directly within the otel-config.yaml file used by the collector. In most cases, you should set up and run an OpenTelemetry Collector on the same system that hosts the Java Agent.
