Chapter 5. Cluster overview page
The Cluster overview page shows the status of a Kafka cluster. Use this page to assess broker readiness, identify cluster errors or warnings, and monitor overall health.
At a glance, the page displays:
- Number of topics and partitions
- Replication status
Cluster metrics:
- Used disk space
- CPU utilization
- Memory usage
Topic metrics:
- Total incoming byte rate
- Total outgoing byte rate
These metrics are presented in charts for quick scanning and analysis of cluster performance.
To view more information, click on the broker and topic-related links.
5.1. Pausing reconciliation of clusters
Pause cluster reconciliation from the Cluster overview page. While reconciliation is paused, changes to the cluster configuration using the Kafka custom resource are ignored until reconciliation is resumed.
Procedure
Log in to the Kafka cluster in the Streams for Apache Kafka Console.
On the Cluster overview page, click Pause reconciliation.
- Confirm the pause, after which the Cluster overview page shows a change of status warning that reconciliation is paused.
- Click Resume reconciliation to restart reconciliation.
If the status change is not displayed after pausing reconciliation, try refreshing the page.
Retrieve the necessary connection details from the Cluster overview page to connect a client to a Kafka cluster.
Procedure
Log in to the Kafka cluster in the Streams for Apache Kafka Console.
On the Cluster overview page, click Cluster connection details.
- Copy the bootstrap address (external or internal, depending on your client environment).
- Add any required connection properties to your Kafka client configuration to establish a secure connection.
Ensure that the authentication type configured for the Kafka cluster matches the authentication type used by the client.
