Alternatively, configure the endpoints by providing the port through the environment variables:

- For gRPC (`0.0.0.0:4317`): `DD_OTLP_CONFIG_RECEIVER_PROTOCOLS_GRPC_ENDPOINT`
- For HTTP (`0.0.0.0:4318`): `DD_OTLP_CONFIG_RECEIVER_PROTOCOLS_HTTP_ENDPOINT`
- For gRPC (`localhost:4317`): `DD_OTLP_CONFIG_RECEIVER_PROTOCOLS_GRPC_ENDPOINT`
- For HTTP (`localhost:4318`): `DD_OTLP_CONFIG_RECEIVER_PROTOCOLS_HTTP_ENDPOINT`
