Amazon API Gateway

Overview

Amazon API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale.

Enable this integration to see in Datadog all your API Gateway metrics.

Setup

Installation

If you haven’t already, set up the Amazon Web Services integration first.

Metric collection

1. In the AWS integration page, ensure that API Gateway is enabled under the Metric Collection tab.

2. Add the following permissions to your Datadog IAM policy in order to get custom tags applied to API Gateway Stages

   • apigateway:GET
   • tag:GetResources

3. Install the Datadog - AWS API Gateway integration.

Note: If you’ve enabled detailed CloudWatch metrics, you must enable them for all Resources or Routes within a Stage. Otherwise, aggregate values in Datadog will be incorrect.

Log collection

Enable API Gateway logging:

1. Go to API Gateway in your AWS console.

2. Select the wanted API and go to the Stages section.

3. In the Logs tab, enable Enable CloudWatch Logs and Enable Access Logging.

4. Select the INFO level to make sure you have all the requests.

5. Make sure your CloudWatch Group name starts with api-gateway.

6. Select the JSON format (CLF and CSV are also supported) and add the following in the Log format box:

   {
       "requestId":"$context.requestId",
       "ip":"$context.identity.sourceIp",
       "caller":"$context.identity.caller",
       "user":"$context.identity.user",
       "requestTime":$context.requestTimeEpoch,
       "httpMethod":"$context.httpMethod",
       "resourcePath":"$context.resourcePath",
       "status":$context.status,
       "protocol":"$context.protocol",
       "responseLength":$context.responseLength
   }
   

Send logs to Datadog

1. If you haven’t already, set up the Datadog log collection AWS Lambda function.
2. Once the lambda function is installed, manually add a trigger on the CloudWatch Log group that contains your API Gateway logs in the AWS console. Select the corresponding CloudWatch Log group, add a filter name (but feel free to leave the filter empty) and add the trigger.

Once done, go in your Datadog Log section to start exploring your logs!
