# Review prebuilt HAProxy alerts

The Install button from the previous step also added prebuilt alert rules to your Grafana instance. These alerts monitor common HAProxy failure modes so you can respond before users are affected.

To review prebuilt HAProxy alerts, complete the following steps:

1. Navigate to **Alerts & IRM > Alerting > Alert rules**.
2. The HAProxy integration includes three alert rules:

   | Alert                           | Fires when                         |
   |---------------------------------|------------------------------------|
   | **HAProxyDroppingLogs**         | HAProxy is dropping logs           |
   | **HAProxyBackendCheckFlapping** | Backend health checks are flapping |
   | **HAProxyServerCheckFlapping**  | Server health checks are flapping  |

You can customize these alerts or create new ones from the **Alerts & IRM > Alerting** page. For example, you might add alerts for high backend response times or connection errors exceeding a threshold.
