Apache HTTP server integration for Grafana Cloud

Apache HTTP server integration is an observability package of dashboards and alerts filled with metrics and logs.

This integration includes 5 useful alerts and 2 pre-built dashboards to help monitor and visualize Apache HTTP server metrics and logs.

Before you begin

Metrics are scraped from server-status page.

To enable it, add this code to your httpd.conf configuration file

<Location "/server-status">
    SetHandler server-status
</Location>

For more information please check the official guide.

Install Apache HTTP server integration for Grafana Cloud

In your Grafana Cloud stack, click Connections in the left-hand menu.
Find Apache HTTP server and click its tile to open the integration.
Review the prerequisites in the Configuration Details tab and set up Grafana Agent to send Apache HTTP server metrics and logs to your Grafana Cloud instance.
Click Install to add this integration’s pre-built dashboards and alerts to your Grafana Cloud instance, and you can start monitoring your Apache HTTP server setup.

Configuration snippets for Grafana Alloy

Simple mode

These snippets are configured to scrape a single Apache HTTP server instance running locally with default ports.

First, manually copy and append the following snippets into your alloy configuration file.

Advanced mode

The following snippets provide examples to guide you through the configuration process.

To instruct Grafana Alloy to scrape your Apache HTTP server instances, manually copy and append the snippets to your alloy configuration file, then follow subsequent instructions.

This integrations uses the prometheus.exporter.apache component to generate metrics from a Apache HTTP server instance.

For the full array of configuration options, refer to the prometheus.exporter.apache component reference documentation.

This exporter must be linked with a discovery.relabel component to apply the necessary relabelings.

For each Apache HTTP server instance to be monitored you must create a pair of these components.

Configure the following properties within each discovery.relabel component:

instance label: constants.hostname sets the instance label to your Grafana Alloy server hostname. If that is not suitable, change it to a value uniquely identifies this Apache HTTP server instance. Make sure this label value is the same for all telemetry data collected for this instance.

You can then scrape them by including each discovery.relabel under targets within the prometheus.scrape component.

Grafana Agent static configuration (deprecated)

The following section shows configuration for running Grafana Agent in static mode which is deprecated. You should use Grafana Alloy for all new deployments.

Before you begin

Metrics are scraped from server-status page.

To enable it, add this code to your httpd.conf configuration file

<Location "/server-status">
    SetHandler server-status
</Location>

For more information please check the official guide.

Install Apache HTTP server integration for Grafana Cloud

In your Grafana Cloud stack, click Connections in the left-hand menu.
Find Apache HTTP server and click its tile to open the integration.
Review the prerequisites in the Configuration Details tab and set up Grafana Agent to send Apache HTTP server metrics and logs to your Grafana Cloud instance.
Click Install to add this integration’s pre-built dashboards and alerts to your Grafana Cloud instance, and you can start monitoring your Apache HTTP server setup.

Post-install configuration for the Apache HTTP server integration

After enabling the metrics generation, instruct Grafana Agent to scrape your Apache HTTP nodes.

Apache HTTP exposes a /server-status?auto endpoint. To scrape it, add the snippets above to your agent configuration file.

This integration supports metrics and logs from Apache HTTP server. If you want to see your logs and metrics correlated on your dashboards, as a single pane of glass, do the following:

job and instance label values must match for apache_http integration and logs scrape config in the agent configuration file.
job label must be set to integrations/apache_http (already configured in the snippets)
instance label must be set to a value that uniquely identifies your Apache Http Node. Replace <yourhostname> in the snippets with a value appropriate to your environment.

Make sure to change targets in the snippet according to your environment.

Logs are scraped from access.log and error.log files. Make sure to point the agent to these locations.

Configuration snippets for Grafana Agent

This integration relies on the Agent exporter, which is provided by default (with a reduced set of metrics) when you installed Grafana Agent.

Replace the existing agent entry with the one provided here.

Below integrations, insert the following lines, following the instructions above:

  apache_http:
    enabled: true
    instance: '<your-instance-name>'
    # job is integrations/apache_http by default
    scrape_uri: 'http://localhost:8080/server-status?auto'
  agent:
    enabled: true
    metric_relabel_configs:
    # required for apache integration.
    # scraping agent endpoint is required for apache histogram metric collection.
      - source_labels: [exported_job]
        target_label: job
      - source_labels: [exported_instance]
        target_label: instance
      - regex: (exported_instance|exported_job)
        action: labeldrop

Below logs.configs.scrape_configs, insert the following lines according to your environment.

    - job_name: integrations/apache_error
      static_configs:
      - targets:

Changelog

# 1.0.1 - October 2024

* Update Alloy snippets to properly pass job label from alloy histogram data

# 1.0.0 - July 2024

* Update mixin - fix issue with the HTTP code histogram panel
* Update Alloy snippets to generate HTTP code histograms from access log

# 0.0.3 - September 2023

* New Filter Metrics option for configuring the Grafana Agent, which saves on metrics cost by dropping any metric not used by this integration. Beware that anything custom built using metrics that are not on the snippet will stop working.
* New hostname relabel option, which applies the instance name you write on the text box to the Grafana Agent configuration snippets, making it easier and less error prone to configure this mandatory label.

# 0.0.2 - August 2023

* Add regex filter for logs datasource

# 0.0.1 - June 2022

* Initial release

Cost

By connecting your Apache HTTP server instance to Grafana Cloud, you might incur charges. To view information on the number of active series that your Grafana Cloud account uses for metrics included in each Cloud tier, see Active series and dpm usage and Cloud tier pricing.
