Grafana Alloy is the new name for our distribution of the OTel collector. Grafana Agent has been deprecated and is in Long-Term Support (LTS) through October 31, 2025. Grafana Agent will reach an End-of-Life (EOL) on November 1, 2025. Read more about why we recommend migrating to Grafana Alloy.

Important: This documentation is about an older version. It's relevant only to the release noted, many of the features and functions have been updated or replaced. Please view the current version.

Open source


The kafka_exporter_config block configures the kafka_exporter integration, which is an embedded version of kafka_exporter. This allows for the collection of Kafka Lag metrics and exposing them as Prometheus metrics.

We strongly recommend that you configure a separate user for the Agent, and give it only the strictly mandatory security privileges necessary for monitoring your node, as per the documentation.

  # Sets an explicit value for the instance label when the integration is
  # self-scraped. Overrides inferred values.
  # The default value for this integration is inferred from the hostname
  # portion of the first kafka_uri value. If there is more than one string
  # in kafka_uri, the integration will fail to load and an instance value
  # must be manually provided.
