 To integrate DCGM-Exporter with Prometheus and Grafana, see the full instructions in the [user guide](https://docs.nvidia.com/datacenter/cloud-native/gpu-telemetry/latest/).
 `dcgm-exporter` is deployed as part of the GPU Operator. To get started with integrating with Prometheus, check the Operator [user guide](https://docs.nvidia.com/datacenter/cloud-native/gpu-operator/getting-started.html#gpu-telemetry).
 
+### Scraping with OpenTelemetry Collector
+
+Because DCGM-Exporter exposes Prometheus-format metrics, it can be scraped by the OpenTelemetry Collector using the Prometheus receiver.
+
+```yaml
+receivers:
+  prometheus:
+    config:
+      scrape_configs:
+        - job_name: dcgm-exporter
+          static_configs:
+            - targets: ["localhost:9400"]
+
+exporters:
+  debug:
+
+service:
+  pipelines:
+    metrics:
+      receivers: [prometheus]
+      exporters: [debug]
+```
+
+In Kubernetes, replace `localhost:9400` with the `dcgm-exporter` service name and port. Replace the `debug` exporter with the exporter for your metrics backend.

 ### TLS and Basic Auth
 
 Exporter supports TLS and basic auth using [exporter-toolkit](https://github.com/prometheus/exporter-toolkit). To use TLS and/or basic auth, users need to use `--web-config-file` CLI flag as follows
