Caution

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.

blackbox_config next

The blackbox_config block configures the blackbox_exporter integration, which is an embedded version of blackbox_exporter. This allows for the collection of blackbox metrics (probes) and exposing them as Prometheus metrics.

Quick configuration example

To get started, define Blackbox targets in Grafana Agent’s integration block:

yaml 
metrics:
  wal_directory: /tmp/wal
  configs:
    - name: default
integrations:
  blackbox:
    blackbox_targets:
      - name: example
        address: http://example.com
        module: http_2xx
    blackbox_config:
      modules:
        http_2xx:
          prober: http
          timeout: 5s
          http:
            method: POST
            headers:
              Content-Type: application/json
            body: '{}'
            preferred_ip_protocol: "ip4"

Full reference of options:

yaml 
  # Provide an explicit value to uniquely identify this instance of the
  # integration. If not provided, a reasonable default will be inferred based
  # on the integration.
  #
  # The value here must be unique across all instances of the same integration.
  [instance: <string>]

  # Override autoscrape defaults for this integration.
  autoscrape:
    # Enables autoscrape of integrations.
    [enable: <boolean> | default = <integrations.metrics.autoscrape.enable>]

    # Specifies the metrics instance name to send metrics to.
    [metrics_instance: <string> | default = <integrations.metrics.autoscrape.metrics_instance>]

    # Autoscrape interval and timeout.
    [scrape_interval: <duration> | default = <integrations.metrics.autoscrape.scrape_interval>]
    [scrape_timeout: <duration> | default = <integrations.metrics.autoscrape.scrape_timeout>]

  # An optional extra set of labels to add to metrics from the integration target. These
  # labels are only exposed via the integration service discovery HTTP API and
  # added when autoscrape is used. They will not be found directly on the metrics
  # page for an integration.
  extra_labels:
    [ <labelname>: <labelvalue> ... ]

  # Exporter-specific configuration options

  # blackbox configuration file with custom modules.
  # This field has precedence to the config defined in the blackbox_config block.
  # See https://github.com/prometheus/blackbox_exporter/blob/master/example.yml for more details how to generate custom blackbox.yml file.
  [config_file: <string> | default = ""]

  # Embedded blackbox configuration. You can specify your modules here instead of an external config file.
  # See https://github.com/prometheus/blackbox_exporter/blob/master/CONFIGURATION.md for more details how to specify your blackbox modules.
  blackbox_config:
    [- <modules> ... ]

  # List of targets to probe
  blackbox_targets:
    [- <blackbox_target> ... ]

  # Option to configure blackbox_exporter.
  # Represents the offset to subtract from timeout in seconds when probing targets.
  [probe_timeout_offset: <float> | default = 0.5]

blackbox_target config

yaml 
  # Name of a blackbox_target
  [name: <string>]

  # The address of the target to probe
  [address: <string>]

  # Blackbox module to use to probe
  [module: <string> | default = ""]
