# Telemetry Reporter Metrics Reference for Confluent Platform #### IMPORTANT **Confluent Health+ is in the End-of-Life (EOL) process.** Health+ is deprecated and users should plan to migrate to Unified Stream Manager (USM). While Health+ remains operational for existing users, it is scheduled to be retired, or to sunset, on December 31, 2026. Starting with Confluent Platform version 8.1, Health+ is discontinued for new deployments and Unified Stream Manager is the recommended alternative for all users. To begin your migration planning, see [Unified Stream Manager (USM) in Confluent Platform](../usm/overview.md#usm-overview). The following tables show the metadata collected by [Telemetry Reporter](telemetry.md#telemetry-reporter) and sent to Confluent to power Health+. Metrics are available for the following Confluent Platform components: - [Kafka Server](#telemetry-reporter-kafka-server) - [ksqlDB Server](#telemetry-reporter-ksqldb) - [Connect](#telemetry-reporter-connect) - [Schema Registry](#telemetry-reporter-sr) - [Java Clients](#telemetry-reporter-java-clients) - [Confluent Control Center](#telemetry-reporter-control-center) - [System](#telemetry-reporter-system) - [Kafka broker configuration](#telemetry-reporter-kafka-broker-config) - [Cluster Linking](#telemetry-reporter-cluster-linking) ## Metadata tags Additional metadata tags are attached to each metric record received, enables storing and associating the metric with the correct resource. | Tag name | Description | |--------------------|------------------------------------------------------------| | `kafka.cluster.id` | Unique Kafka cluster ID | | `kafka.version` | Kafka version of broker | | `kafka.broker.id` | Unique broker identifier in Kafka cluster | | `java.version` | Java version of broker | | `host.hostname` | Host name for broker | | `topic` | Topic name.
