prometheus.exporter.self

The prometheus.exporter.self component collects and exposes metrics about Alloy itself.

Usage

alloy Copy

prometheus.exporter.self "alloy" {
}

Arguments

prometheus.exporter.self accepts no arguments.

Exported fields

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

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.self is only reported as unhealthy if given an invalid configuration.

Debug information

prometheus.exporter.self doesn’t expose any component-specific debug information.

Debug metrics

prometheus.exporter.self doesn’t expose any component-specific debug metrics.

Example

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

alloy Copy

prometheus.exporter.self "example" {}

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