**Note**: The Prometheus feature is available for Litmus Edge Manager 2.10.1 and later.
:::

Litmus Edge Manager (LEM) supports the integration of a Prometheus monitoring system for collecting metrics data. From this integration's metrics data, you may connect the Prometheus monitor system to a third-party client (such as Grafana) to retrieve, access, and use the metrics data for a more thorough analysis. 

Litmus Edge Manager also supports the ability to connect to an external Alert Manager. When successfully connected, the [Incidents](docId:81uhi0Waj080EuLYceOaf) alerts are sent to the external Alert Manager. This enables you to use an external Alert Manager of your choice to provide a more comprehensive alert management system.

# Access Prometheus UI

**To access the Prometheus UI: **

1. Log in to the Litmus Edge Manager (LEM) Admin Console at the following URL: `https://[LEM IP address]:8446`.
2. From the navigation panel, select **Integration**.
   The *Kafka* pane by default appears. 
3. From Integration's navigation sub-panel, select **Prometheus**.
   The *Prometheus* pane appears.

Refer to the following actions you can take on the *Prometheus* pane.
