AWS Trusted Advisor now supports a new fault tolerance check for too many partitions per broker on Amazon Managed Streaming for Apache Kafka (Amazon MSK). AWS Trusted Advisor helps you optimize costs, increase performance, improve security and resilience, and operate at scale in the cloud.

The Amazon MSK fault tolerance check inspects if you are approaching or have exceeded the recommended number of partitions per broker on your MSK cluster. Having too many partitions can affect the performance of your cluster. This check is available in all commercial Regions. For more information on availability, please see the AWS Region table.

AWS Premium Support customers can access the fault tolerance checks from the AWS Trusted Advisor Console, or via the AWS Support API. For more information please visit the AWS Trusted Advisor webpage and the documentation site for a complete list of check references.
