Caution

Grafana Agent has reached End-of-Life (EOL) on November 1, 2025. Agent is no longer receiving vendor support and will no longer receive security or bug fixes. Current users of Agent Static mode, Agent Flow mode, and Agent Operator should proceed with migrating to Grafana Alloy. If you have already migrated to Alloy, no further action is required. Read more about why we recommend migrating to Grafana Alloy.

prometheus.exporter.apache

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

Usage

Alloy 
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.

NameTypeDescriptionDefaultRequired
scrape_uristringURI to Apache stub status page.http://localhost/server-status?autono
host_overridestringOverride for HTTP Host header.no
insecureboolIgnore server certificate if using https.falseno

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.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:

Alloy 
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.

Compatible components

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