Monitor replication - Amazon Managed Streaming for Apache Kafka
Services or capabilities described in AWS documentation might vary by Region. To see the differences applicable to the AWS European Sovereign Cloud Region, see the AWS European Sovereign Cloud User Guide.

Monitor replication

You can use Amazon CloudWatch in the target cluster Region to view metrics for ReplicationLatency, MessageLag, and ReplicatorThroughput at a topic and aggregate level for each MSK Replicator. Metrics are visible under ReplicatorName in the "AWS/Kafka" namespace. You can also see ReplicatorFailure, AuthError, and ThrottleTime metrics to check for issues.

The MSK console displays a subset of CloudWatch metrics for each MSK Replicator. From the console Replicator list, select the name of a Replicator and select the Monitoring tab.

You can also enable log forwarding for your MSK Replicator to gain deeper visibility into replication operations and simplify troubleshooting. MSK Replicator supports forwarding operational logs to Amazon CloudWatch Logs, Amazon S3, and Amazon Data Firehose. By default, log delivery is not enabled. You can configure log delivery when you create or update a Replicator using the logDelivery configuration in the CreateReplicator or UpdateReplicator API request.
