Chapter 5. Cluster overview page
The Cluster overview page shows the status of a Kafka cluster. Here, you can assess the readiness of Kafka brokers, identify any cluster errors or warnings, and gain insights into the cluster’s health. At a glance, the page provides information on the number of topics and partitions within the cluster, along with their replication status. Explore cluster metrics through charts displaying used disk space, CPU utilization, and memory usage. Additionally, topic metrics offer a comprehensive view of total incoming and outgoing byte rates for all topics in the Kafka cluster.
5.1. Pausing reconciliation of clusters
Pause cluster reconciliations from the Cluster overview page by following these steps. While paused, any changes to the cluster configuration using the Kafka custom resource are ignored until reconciliation is resumed.
Procedure
- From the Streams for Apache Kafka Console, log in to the Kafka cluster that you want to connect to, then click Cluster overview and 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.
When connecting a client to a Kafka cluster, retrieve the necessary connection details from the Cluster overview page by following these steps.
Procedure
- From the Streams for Apache Kafka Console, log in to the Kafka cluster that you want to connect to, then click Cluster overview and Cluster connection details.
- Copy and add bootstrap address and connection properties to your Kafka client configuration to establish a connection with the Kafka cluster.
Ensure that the authentication type used by the client matches the authentication type configured for the Kafka cluster.
