+Alloy has a Prometheus scrape endpoint, `/metrics`, that you can use to check metrics locally by opening a browser to `http://localhost:12345/metrics`.
+The `/metrics` HTTP endpoint of the Alloy HTTP server exposes the Alloy component and controller metrics.
+Refer to the [Monitor the Grafana Alloy component controller](https://grafana.com/docs/alloy/latest/troubleshoot/controller_metrics/) documentation for more information.
+
+### Check metrics in Grafana Cloud
+
+In your Grafana Cloud instance, you can check metrics using the `grafanacloud-usage` data source.
+To view the metrics, use the following steps:
+
+1. From your Grafana instance, select **Explore** in the left menu.
+1. Change the data source to `grafanacloud-usage`.
+1. Type the metric to verify in the text box. If you start with `grafanacloud_traces_`, you can  use autocomplete to browse the list of available metrics.
+
+Refer to [Cloud Traces usage metrics](https://grafana.com/docs/grafana-cloud/cost-management-and-billing/understand-your-invoice/usage-limits/#cloud-traces-usage) for a list of metrics related to tracing usage.

 ## Trace span logging
 
 If metrics and logs are looking good, but you are still unable to find traces in Grafana Cloud, you can configure Alloy to output all the traces it receives to the [console](https://grafana.com/docs/tempo/<TEMPO_VERSION>/configuration/grafana-alloy/automatic-logging/).
