+### OTLP Export Sample with GCP Auth
+This example shows how to send metrics to an OTLP (OpenTelemetry Protocol) endpoint that is protected by GCP authentication. The sample showcases the metric export using gRPC.
+
+#### Installation
+Install the dependencies and libraries required to run the samples:
+
+```sh
+# Move to the sample repository
+cd samples/otlpmetric
+
+pip install -r requirements.txt
+```
+
+#### Prerequisites
+Get Google credentials on your machine:
+
+```sh
+gcloud auth application-default login
+```
+
+#### Run the Sample
+```sh
+# export necessary OTEL environment variables
+export PROJECT_ID=<project-id>
+export OTEL_EXPORTER_OTLP_ENDPOINT=<endpoint>
+export OTEL_RESOURCE_ATTRIBUTES="gcp.project_id=$PROJECT_ID,service.name=otlp-sample,service.instance.id=1"
+
+# from the samples/otlpmetric repository
+python3 example.py
+```
