Fastly dashboard showing cache hit ratio, success rate, and other metrics

Overview

Connect Fastly to Datadog to view key Fastly metrics (for example, cache coverage and header size) in context with the rest of your Datadog metrics.

The integration includes out-of-the-box monitors and dashboard that enable you to view metrics in aggregate, pivot between Fastly metrics and related logs, and create monitors that alert you when a metric passes a user-defined threshold or behaves anomalously.

Setup

Installation

No installation steps required.

Configuration

Metric collection

Create a Read-only access API token on Fastly’s token management page, get your Service ID from the Dashboard and enter them in the Fastly integration tile.

The ServiceID is the alphanumerical code, for example: 5VqE6MOOy1QFJbgmCK41pY (example from the Fastly API documentation).

If you are using multiple Service IDs from one account, enter an API token on each line.

The account name is a way for you to organize your accounts, and is not used as part of the data ingestion process.

Log collection

Log collection is not supported for this site.

Configure the Datadog endpoint to forward Fastly logs to Datadog. You can choose the Datadog or Datadog (via Syslog) endpoint. The Datadog endpoint is recommended for more reliable delivery of logs over Syslog.

Select the logging endpoint
  1. Log in to the Fastly web interface and click Configure link.
  2. From the Service menu, select the appropriate service.
  3. Click the Configuration button and then select Clone active. The Domains page appears.
  4. Click the Logging link. The logging endpoints page appears. Click Create Endpoint under Datadog or the Datadog (with Syslog) options.
  1. Give a name to the endpoint, for example: Datadog.
  2. Configure the log format. By default, the recommended Datadog-Fastly log format is already provided and can be customized.
  3. Select your region to match your Datadog account region:
  4. Add your Datadog API key.
  5. Click Create at the bottom.
  6. Click Activate at the top right to activate the new configuration. After a few minutes, logs should begin flowing into your account.
Configure the Syslog endpoint

  1. Give a name to the endpoint, for example: Datadog.

  2. Configure the log format to include the recommended Datadog-Fastly log format with your Datadog API key at the beginning. See Using the JSON logging format in the Fastly documentation for an example.

    <DATADOG_API_KEY> <DATADOG_FASTLY_LOG_FORMAT>

    Note: Your Datadog API key MUST be in front of the Datadog-Fastly log format for your logs to display in Datadog. See Useful variables to log for more details.

  3. Set Syslog Address to:

  4. Set Port to:

  5. Set TLS to yes

  6. Set TLS Hostname to:

  7. In the advanced option section, select Blank as log line format

  8. Finally, save the endpoint and deploy the service. See the logs in your Datadog Logs Explorer.
