# Apache Web Server Metrics

The [Apache receiver](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/receiver/apachereceiver) collects Apache Web Server metrics.

For more information, see the OpenTelemetry project documentation for the [Apache receiver](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/receiver/apachereceiver).

## Setup{% #setup %}

This example uses component identifiers from OpenTelemetry Collector Contrib v0.154.0. For other versions or distributions, use the identifiers your distribution supports.

The Apache receiver reads your server's `server-status?auto` page. Before you start, [enable `mod_status`](https://httpd.apache.org/docs/2.4/mod/mod_status.html) on your Apache server. Limit access to the status page, for example to localhost, because it shows details about your server and its requests.

Add the following lines to your Collector configuration, and set `endpoint` to the address of your status page:

```yaml
receivers:
  apache:
    endpoint: http://localhost:8080/server-status?auto
```

Add `apache` to the `receivers` list of the metrics pipeline in your configuration. Keep the processors already in that pipeline. The Datadog OTLP metrics intake accepts only delta metrics, and this receiver produces cumulative sums, so the pipeline needs `cumulativetodelta`. The [recommended Collector setup](https://docs.datadoghq.com/opentelemetry/setup/collector_exporter.md) includes it.

For all configuration options, see the [Apache receiver documentation](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/receiver/apachereceiver).
