Verify metrics appear in Grafana Cloud

After configuring the integration, verify that HAProxy metrics are flowing into Grafana Cloud. This step confirms that Alloy is scraping the stats endpoint and successfully forwarding data.

1. Click Explore in the left-side menu.

2. Select your Prometheus data source from the data source picker.

3. In the Metric field, type haproxy_frontend_http_requests_total and select it from the dropdown.

4. Click Run query. If data appears, HAProxy metrics are being collected successfully.

5. If no data appears, wait 2-3 minutes for the first scrape to complete, then try again.

   You can also try up{job=~".*haproxy.*"} to confirm the scrape target is healthy. A value of 1 means the target is up and being scraped.
