This page explains how to access the Apache Spark™ UI of your Apache Spark™ cluster.

<Requirements />

- A Scaleway account logged into the [console](https://console.scaleway.com)
- [Owner](/iam/concepts/#owner) status or [IAM permissions](/iam/concepts/#permission) allowing you to perform actions in the intended Organization
- Created an [Apache Spark™ cluster](/apache-spark/how-to/create-spark-cluster/)
- Created an [IAM API key](/iam/how-to/create-api-keys/)

1. Click **Apache Spark™** under **Data & Analytics** on the side menu. The **Clusters for Apache Spark™** page displays.

2. Click the name of the desired cluster. The **Overview** tab of the cluster displays.

3. Click the **Open Apache Spark™ UI** button. A login page displays.

4. Enter the **secret key** of your API key, then click **Authenticate**. The Apache Spark™ UI dashboard displays.

From this page, you can view and monitor worker nodes, executors, and applications.
