After the Kafka component is installed in an MRS cluster, you can use Kafka UI to query cluster information, node status, topic partitions, and data production and consumption details. Kafka UI provides a GUI for users to create and delete topics, modify configurations, as well as add and migrate partitions, simplifying user operations and improving O&M efficiency.
You have created a user who has the permission to access Kafka UI. To perform related operations on the page, for example, creating a topic, you need to grant related permissions to the user. For details, see Managing Kafka User Permissions.
Site trust must be added to the browser when you access Manager and Kafka UI for the first time. Otherwise, Kafka UI cannot be accessed.
