MSK clusters should have enhanced monitoring configured

How to fix it

In the console

Managed Streaming for Apache Kafka → Clusters → the cluster → Actions → Edit monitoring

Enhanced topic-level monitoring

Selected (PER_TOPIC_PER_BROKER); partition-level (PER_TOPIC_PER_PARTITION) passes too

With the AWS CLI

aws kafka update-monitoring --cluster-arn <cluster-arn> --current-version <current-version> --enhanced-monitoring PER_TOPIC_PER_BROKER --region <region>

With Terraform

resource "aws_msk_cluster" "this" {
  cluster_name           = var.cluster_name
  kafka_version          = var.kafka_version
  number_of_broker_nodes = var.number_of_broker_nodes
  enhanced_monitoring    = "PER_TOPIC_PER_BROKER"

  broker_node_group_info {
    client_subnets  = var.client_subnets
    instance_type   = var.instance_type
    security_groups = var.security_groups
  }
}
