+# Send Vector logs and metrics to Datadog
+
+In this demo, Vector is running a simple topology in which the `generator` source emits random JSON
+logs twice per second and sends those logs off to stdout via the `console` sink. But even this
+simple pipeline is enough to generate internal logs and metrics for Vector (via the eponymous
+sources).
+
+To run this scenario, make sure you have the `DD_API_KEY` environment variable set to your Datadog
+API key and then run:
+
+```bash
+docker compose up --detach
+```
+
+Once Vector is up and running, check out the [Logs exporer][logs] and this simple
+[Metrics dashboard][metrics].
+

+[metrics]: https://app.datadoghq.com/metric/explorer?live=true&tile_size=m&exp_metric=vector.events_in_total&exp_agg=avg&exp_row_type=metric
