  • For Confluent Platform 7.5, Control Center only supports patch version: 7.5.11

  • For Confluent Platform 7.6, Control Center only supports patch version: 7.6.8

Considerations:

  • Control Center is backward compatible with the list of supported Confluent Platform versions above

  • Control Center requires a minimum of Java 17

  • If you can’t upgrade to Java 17, consider using Control Center (Legacy) which requires Java 11

  • Use Confluent Platform 7.9 to export metrics with mTLS (communication between Kafka and Control Center)

  • Use Confluent Platform 7.7, or Confluent Platform 7.8 to export metrics with TLS and Basic Auth (communication between Kafka and Control Center)

  • Confluent Platform 8.0 and higher supports only KRaft mode.

  • For ZooKeeper, use a supported version of Confluent Platform from Confluent Platform 7.9 or earlier

System requirements

Control Center monitors larger workloads compared to previous versions of Control Center (Legacy).

For monitoring clusters with 100k replicas or less (most common):

  • Memory: 8 GB

  • Storage: 200 GB (preferably SSD)

  • CPU: 4 cores

For monitoring clusters with more than 100k replicas:

  • Memory: 16 GB

  • Storage: 300 GB (preferably SSD)

  • CPU: 8 cores

For monitoring clusters with 200k - 400k replicas, use the configurations mentioned in the multi-node manual install. Alternatively, adjust the allocated memory, storage, and CPU parameters to accommodate the increased workload.

Considerations:

  • Storage requirements are based on default metrics retention of 15 days. If you configure a different retention, you must proportionately adjust storage.

    For example:

    • If you set metric retention from 15 to 30 days, you should double storage

    • If you set metric retention from 15 to 7 days, you should halve storage

  • You can configure the default Control Center network port.

  • Using a proxy to control and secure access to Control Center is supported.
