Configure Grafana Agentintegrations_configblackbox_config

blackbox_config

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:

metrics:
  wal_directory: /tmp/wal
integrations:
  blackbox:
    enabled: true
    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:

  # Enables the blackbox_exporter integration, allowing the Agent to automatically
  # collect system metrics from the configured statsd server address
  [enabled: <boolean> | default = false]

  # 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 agent hostname
  # and HTTP listen port, delimited by a colon.
  [instance: <string>]

  # Automatically collect metrics from this integration. If disabled,
  # the blackbox_exporter integration will be run but not scraped and thus not
  # remote-written. Metrics for the integration will be exposed at
  # /integrations/blackbox_exporter/metrics and can be scraped by an external
  # process.
  [scrape_integration: <boolean> | default = <integrations_config.scrape_integrations>]

  # How often should the metrics be collected? Defaults to
  # prometheus.global.scrape_interval.
  [scrape_interval: <duration> | default = <global_config.scrape_interval>]

  # The timeout before considering the scrape a failure. Defaults to
  # prometheus.global.scrape_timeout.
  [scrape_timeout: <duration> | default = <global_config.scrape_timeout>]

  # Allows for relabeling labels on the target.
  relabel_configs:
    [- <relabel_config> ... ]

  # Relabel metrics coming from the integration, allowing to drop series
  # from the integration that you don't care about.
  metric_relabel_configs:
    [ - <relabel_config> ... ]

  # How frequent to truncate the WAL for this integration.
  [wal_truncate_frequency: <duration> | default = "60m"]

  # Monitor the exporter itself and include those metrics in the results.
  [include_exporter_metrics: <bool> | default = false]
