The prometheus.exporter.dnsmasq component embeds dnsmasq_exporter for collecting statistics from a dnsmasq server.


prometheus.exporter.dnsmasq "LABEL" {


The following arguments can be used to configure the exporter’s behavior. All arguments are optional. Omitted fields take their default values.

addressstringThe address of the dnsmasq server."localhost:53"no
leases_filestringThe path to the dnsmasq leases file."/var/lib/misc/dnsmasq.leases"no
expose_leasesboolExpose dnsmasq leases as metrics (high cardinality).falseno

Exported fields

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

targetslist(map(string))The targets that can be used to collect exporter metrics.

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

Debug information

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

Debug metrics

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


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

prometheus.exporter.dnsmasq "example" {
  address = "localhost:53"

// Configure a prometheus.scrape component to collect github metrics.
prometheus.scrape "demo" {
  targets    = prometheus.exporter.dnsmasq.example.targets
  forward_to = [prometheus.remote_write.demo.receiver]

prometheus.remote_write "demo" {
  endpoint {

    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.
