prometheus.exporter.dnsmasq
The prometheus.exporter.dnsmasq
component embeds
dnsmasq_exporter for collecting statistics from a dnsmasq server.
Usage
prometheus.exporter.dnsmasq "LABEL" {
}
Arguments
The following arguments can be used to configure the exporter’s behavior. All arguments are optional. Omitted fields take their default values.
Name | Type | Description | Default | Required |
---|---|---|---|---|
address | string | The address of the dnsmasq server. | "localhost:53" | no |
leases_file | string | The path to the dnsmasq leases file. | "/var/lib/misc/dnsmasq.leases" | no |
expose_leases | bool | Expose dnsmasq leases as metrics (high cardinality). | false | no |
Exported fields
The following fields are exported and can be referenced by other components.
Name | Type | Description |
---|---|---|
targets | list(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.
Example
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 {
url = PROMETHEUS_REMOTE_WRITE_URL
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.
