This is documentation for the next version of Alloy. For the latest stable release, go to the latest version.

Open source

prometheus.exporter.squid

The prometheus.exporter.squid component embeds squid_exporter for collecting metrics from a squid instance.

Usage

alloy
prometheus.exporter.squid "LABEL" {
    address = SQUID_ADDRESS
}

Arguments

You can use the following arguments to configure the exporter’s behavior. Omitted fields take their default values.

NameTypeDescriptionDefaultRequired
addressstringThe squid address to collect metrics from.yes
usernamestringThe username for the user used when querying metrics.no
passwordsecretThe password for the user used when querying metrics.no

Blocks

The prometheus.exporter.squid component does not support any blocks, and is configured fully through arguments.

Exported fields

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

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

Debug information

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

Debug metrics

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

Example

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

alloy
prometheus.exporter.squid "example" {
  address = "localhost:3128"
}

// Configure a prometheus.scrape component to collect squid metrics.
prometheus.scrape "demo" {
  targets    = prometheus.exporter.squid.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.

Compatible components

prometheus.exporter.squid has exports that can be consumed by the following components:

Note

Connecting some components may not be sensible or components may require further configuration to make the connection work correctly. Refer to the linked documentation for more details.
