Unified Stream Manager Control Plane Auditable Event Methods on Confluent Cloud

Confluent Cloud audit logs contain records of auditable events for Unified Stream Manager (USM) control plane operations. When an auditable event occurs, a message is sent to the audit log and is stored as an audit log record.

The following sections describe the auditable event methods for the USM control plane service. Use them to identify and monitor USM operations, such as registering, retrieving, listing, and deregistering on-premises Confluent Platform Kafka and Connect clusters with Confluent Cloud. For details on registering a cluster, see Register Your Confluent Platform Cluster.

USM Kafka cluster

The following operations on registered on-premises Confluent Platform Apache Kafka® clusters generate auditable event messages for the io.confluent.cloud/request event type.

Method name	Action triggering an auditable event message
RegisterUsmKafkaCluster	A request to register an on-premises Confluent Platform Kafka cluster with USM.
GetUsmKafkaCluster	A request to retrieve a registered Kafka cluster.
ListUsmKafkaClusters	A request to list registered Kafka clusters in an environment.
DeregisterUsmKafkaCluster	A request to deregister a Kafka cluster.

RegisterUsmKafkaCluster

The RegisterUsmKafkaCluster event is generated by a request to register an on-premises Confluent Platform Kafka cluster with USM.

HTTP route: POST /usm/v1/kafka-clusters
