+title: Data Collection
+description: Metrics, configurations, and capabilities collected by Data Streams Monitoring's Kafka Monitoring when cluster monitoring is enabled.
+---
+
+Data Streams Monitoring's [Kafka Monitoring][6] uses the [Kafka Consumer integration][1] to collect cluster health data. On top of the integration's defaults, it collects additional data and adds ability to perform actions described in this doc.
+
+## Metrics
+
+To collect the **DSM only** [Kafka Consumer integration metrics][5], set `enable_cluster_monitoring: true`. See [Kafka Monitoring Setup][4] for how to configure the check.
+
+## Configurations and schemas
+
+- Broker configurations
+- Topic configurations
+- Schemas from a schema registry
+
+## Capabilities
+
+Enabling cluster monitoring unlocks the ability to [read live messages on topics][3] on demand. See [Enable message inspection][2] for the additional setup steps.
