The consul_exporter_config block configures the consul_exporter integration, which is an embedded version of consul_exporter. This allows for the collection of consul metrics and exposing them as Prometheus metrics.

Full reference of options:

  1.   # Enables the consul_exporter integration, allowing the Agent to automatically
  2.   # collect system metrics from the configured consul server address
  3.   [enabled: <boolean> | default = false]
  5.   # Sets an explicit value for the instance label when the integration is
  6.   # self-scraped. Overrides inferred values.
  7.   #
  8.   # The default value for this integration is inferred from the hostname portion
  9.   # of the server URL.
  10.   [instance: <string>]
  12.   # Automatically collect metrics from this integration. If disabled,
  13.   # the consul_exporter integration will be run but not scraped and thus not
  14.   # remote-written. Metrics for the integration will be exposed at
  15.   # /integrations/consul_exporter/metrics and can be scraped by an external
  16.   # process.
  17.   [scrape_integration: <boolean> | default = <integrations_config.scrape_integrations>]
  19.   # How often should the metrics be collected? Defaults to
  20.   # prometheus.global.scrape_interval.
  21.   [scrape_interval: <duration> | default = <global_config.scrape_interval>]
  23.   # The timeout before considering the scrape a failure. Defaults to
  24.   # prometheus.global.scrape_timeout.
  25.   [scrape_timeout: <duration> | default = <global_config.scrape_timeout>]
  27.   # Allows for relabeling labels on the target.
  28.   relabel_configs:
  29.     [- <relabel_config> ... ]
  31.   # Relabel metrics coming from the integration, allowing to drop series
  32.   # from the integration that you don't care about.

  36.   # How frequent to truncate the WAL for this integration.

  60.   # Disable TLS host verification.
