Cloudflare integration for Grafana Cloud

Cloudflare is a globally distributed network infrastructure and cybersecurity company that provides content delivery, DDoS mitigation, internet security, and other related services to enhance the performance and security of websites and internet applications. This integration for Grafana Cloud allows users to collect and analyze metrics for Cloudflare Analytics - account and zone analytics, a description of which is found here.

Metrics include requests, bandwidth, CPU utilization, HTTP response codes, pool health, and colocation information. These are used to provide valuable visualizations for zones, workers, and pools.

This integration requires Pro Plan or better Cloudflare subscriptions.

This integration includes 5 useful alerts and 3 pre-built dashboards to help monitor and visualize Cloudflare metrics.

Before you begin

In order for the integration to properly work, you must set up the Cloudflare Prometheus exporter to export metrics from Cloudflare.

Get an API token

It is recommended to authenticate the exporter using an API token, which can be created by following this guide.

This newly created token will also need to be given certain permissions so the exporter can retrieve metrics. These permissions are:

Account Analytics: Read
Account Settings: Read
Analytics: Read

Set up Cloudflare exporter

The exporter can be configured by following this guide.

To build and run the exporter, use the following commands.

This command will build the exporter binary with the name cloudflare_exporter.

make build

This uses the API token authentication method, so be sure to replace <cloudflare-api-token> with the token generated in the previous step. It also uses the useful flag -listen which will set the port metrics are served at. The default port is 8080 which may be an issue if you have a pre-existing process using that port.

./cloudflare_exporter -listen=:<port_number> -cf_api_token=<cloudflare-api-token>

Install Cloudflare integration for Grafana Cloud

In your Grafana Cloud stack, click Connections in the left-hand menu.
Find Cloudflare and click its tile to open the integration.
Review the prerequisites in the Configuration Details tab and set up Grafana Agent to send Cloudflare metrics 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 Cloudflare setup.

Configuration snippets for Grafana Alloy

Advanced mode

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

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

Advanced metrics snippets

prometheus.scrape "metrics_integrations_integrations_cloudflare" {
	targets = [{
		__address__ = "<exporter_hostname>:<exporter_port>",
		instance    = constants.hostname,
	}]
	forward_to = [prometheus.remote_write.metrics_service.receiver]
	job_name   = "integrations/cloudflare"
}

To monitor your Cloudflare instance, you must use a discovery.relabel component to discover your Cloudflare Prometheus endpoint and apply appropriate labels, followed by a prometheus.scrape component to scrape it.

Configure the following properties within each discovery.relabel component:

__address__: The address to your Cloudflare Prometheus metrics endpoint.
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 Cloudflare instance.

If you have multiple Cloudflare servers to scrape, configure one discovery.relabel for each and scrape them by including each 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

In order for the integration to properly work, you must set up the Cloudflare Prometheus exporter to export metrics from Cloudflare.

Get an API token

It is recommended to authenticate the exporter using an API token, which can be created by following this guide.

This newly created token will also need to be given certain permissions so the exporter can retrieve metrics. These permissions are:

Account Analytics: Read
Account Settings: Read
Analytics: Read

Set up Cloudflare exporter

The exporter can be configured by following this guide.

To build and run the exporter, use the following commands.

This command will build the exporter binary with the name cloudflare_exporter.

make build

./cloudflare_exporter -listen=:<port_number> -cf_api_token=<cloudflare-api-token>

Install Cloudflare integration for Grafana Cloud

In your Grafana Cloud stack, click Connections in the left-hand menu.
Find Cloudflare and click its tile to open the integration.
Review the prerequisites in the Configuration Details tab and set up Grafana Agent to send Cloudflare metrics 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 Cloudflare setup.

Post-install configuration for the Cloudflare integration

After enabling the Cloudflare Prometheus exporter, instruct the Grafana Agent to scrape the metrics endpoint.

Be sure to change <exporter_host> and <exporter_port> to match your environment to get the correct label.

Configuration snippets for Grafana Agent

Below metrics.configs.scrape_configs, insert the following lines and change the URLs according to your environment:

    - job_name: integrations/cloudflare
      metrics_path: /metrics
      static_configs:
        - targets:
          - <exporter_hostname>:<exporter_port>
          labels:
            instance: <exporter_hostname>:<exporter_port>
