+metaDescription: The OpenTelemetry collector is a central tool to collect, process, and export your telemetry.
+---
+
+The [OpenTelemetry Collector](https://opentelemetry.io/docs/collector/) is a configurable and extensible software component to receive, process, and export telemetry data. When you set up a collector, it can operate as a gateway or as an agent:
+
+* **Gateway:** The collector receives data from a variety of sources and applies standard processing before exporting to some backend.
+* **Agent:** The collector is deployed on each host in an environment and can collect telemetry data about the host and processes running on it.
+
+When you use a collector, you start by following the same routine as above for setting up OTLP in your service. In this case, instead of exporting data directly to New Relic, you export through a collector that you set up. In the collector, you configure the [OTLP exporter](https://github.com/open-telemetry/opentelemetry-collector/tree/main/exporter/otlpexporter) to export data to New Relic.
+
+When your data goes through a collector, the transport looks like this:

+
+Here's a Docker example of how to set up and run an OpenTelemetry collector with the collector YAML:
+
+1. Save the following as `otel-config.yaml`:
+
+```
+receivers:
+  otlp:
+    protocols:
+      grpc:
+      http:
+
+processors:
+  batch:
+
+exporters:
+  otlp:
+    endpoint: ${OTEL_EXPORTER_OTLP_ENDPOINT}
+    headers:
+      api-key: ${NEW_RELIC_LICENSE_KEY}
+
+service:
+  pipelines:
+    traces:
+      receivers: [otlp]
+      processors: [batch]
+      exporters: [otlp]
+    metrics:
+      receivers: [otlp]
+      processors: [batch]
+      exporters: [otlp]
+    logs:
+      receivers: [otlp]
+      processors: [batch]
+      exporters: [otlp]
+```
+2. Run the OpenTelemetry collector after you make the following changes:
+   * Replace <var>OTLP_ENDPOINT_HERE</var> with the appropriate [endpoint](#review-settings.
+   * Replace <var>YOUR_KEY_HERE</var> with your account's [license key](https://one.newrelic.com/launcher/api-keys-ui.launcher).
+
+```
+export OTEL_EXPORTER_OTLP_ENDPOINT=<var>OTLP_ENDPOINT_HERE</var>
+export NEW_RELIC_LICENSE_KEY=<var>YOUR_KEY_HERE</var>
+
+docker run --rm \
+  -e OTEL_EXPORTER_OTLP_ENDPOINT \
+  -e NEW_RELIC_LICENSE_KEY \
+  -p 4317:4317 \
+  -v "${PWD}/otel-config.yaml":/otel-config.yaml \
+  --name otelcol \
+  otel/opentelemetry-collector \
+  --config otel-config.yaml
+```
+
