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.

dnsmasq_exporter_config

The dnsmasq_exporter_config block configures the dnsmasq_exporter integration, which is an embedded version of dnsmasq_exporter. This allows for the collection of metrics from dnsmasq servers.

Note that currently, an Agent can only collect metrics from a single dnsmasq server. If you want to collect metrics from multiple servers, you can run multiple Agents and add labels using relabel_configs to differentiate between the servers:

yaml 
dnsmasq_exporter:
  enabled: true
  dnsmasq_address: dnsmasq-a:53
  relabel_configs:
  - source_labels: [__address__]
    target_label: instance
    replacement: dnsmasq-a

Full reference of options:

yaml 
  # Enables the dnsmasq_exporter integration, allowing the Agent to automatically
  # collect system metrics from the configured dnsmasq 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 dnsmasq_address
  # value.
  [instance: <string>]

  # Automatically collect metrics from this integration. If disabled,
  # the dnsmasq_exporter integration will be run but not scraped and thus not
  # remote-written. Metrics for the integration will be exposed at
  # /integrations/dnsmasq_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"]

  #
  # Exporter-specific configuration options
  #

  # Address of the dnsmasq server in host:port form.
  [dnsmasq_address: <string> | default = "localhost:53"]

  # Path to the dnsmasq leases file. If this file doesn't exist, scraping
  # dnsmasq # will fail with an warning log message.
  [leases_path: <string> | default = "/var/lib/misc/dnsmasq.leases"]
