prometheus.exporter.apache

The prometheus.exporter.apache component embeds apache_exporter for collecting mod_status statistics from an apache server.

Usage

prometheus.exporter.apache "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
`scrape_uri`	`string`	URI to Apache stub status page.	`http://localhost/server-status?auto`	no
`host_override`	`string`	Override for HTTP Host header.		no
`insecure`	`bool`	Ignore server certificate if using https.	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 will use the configured in-memory traffic address specified by the run command.

Component health

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

Debug information

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

Debug metrics

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

Example

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

prometheus.exporter.apache "example" {
  scrape_uri = "http://web.example.com/server-status?auto"
}

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