prometheus.exporter.kafka

The prometheus.exporter.kafka component embeds kafka_exporter for collecting metrics from a kafka server.

Usage

alloy Copy

prometheus.exporter.kafka "LABEL" {
    kafka_uris = KAFKA_URI_LIST
}

Arguments

You can use the following arguments to configure the exporter’s behavior. Omitted fields take their default values.

Exported fields

The following fields are exported and can be referenced by other components.

For example, the targets can either be passed to a discovery.relabel component to rewrite the targets’ label sets or to a prometheus.scrape component that collects the exposed metrics.

The exported targets use the configured in-memory traffic address specified by the run command.

Component health

prometheus.exporter.kafka is only reported as unhealthy if given an invalid configuration. In those cases, exported fields retain their last healthy values.

Debug information

prometheus.exporter.kafka does not expose any component-specific debug information.

Debug metrics

prometheus.exporter.kafka does not expose any component-specific debug metrics.

Example

This example uses a prometheus.scrape component to collect metrics from prometheus.exporter.kafka:

alloy Copy

prometheus.exporter.kafka "example" {
  kafka_uris = ["localhost:9200"]
}

// Configure a prometheus.scrape component to send metrics to.
prometheus.scrape "demo" {
  targets    = prometheus.exporter.kafka.example.targets
  forward_to = [prometheus.remote_write.demo.receiver]
}

prometheus.remote_write "demo" {
  endpoint {
    url = PROMETHEUS_REMOTE_WRITE_URL

    basic_auth {
      username = USERNAME
      password = PASSWORD
    }
  }
}

Replace the following:

• PROMETHEUS_REMOTE_WRITE_URL: The URL of the Prometheus remote_write-compatible server to send metrics to.
• USERNAME: The username to use for authentication to the remote_write API.
• PASSWORD: The password to use for authentication to the remote_write API.
