Overview

Use AWS NAT Gateway to enable instances in a private subnet to connect to the internet, but prevent the internet from initiating connections with the instances.

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

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 NATGateway is enabled under the Metric Collection tab.
2. Install the Datadog - AWS NAT Gateway integration.

Log collection

Enable logging

Configure AWS NAT Gateway to send logs either to a S3 bucket or to CloudWatch.

Note: If you log to a S3 bucket, make sure that amazon_nat_gateway is set as Target prefix.

Send logs to Datadog

1. If you haven’t already, set up the Datadog Forwarder Lambda function.

2. Once the Lambda function is installed, manually add a trigger on the S3 bucket or CloudWatch log group that contains your AWS NAT Gateway logs in the AWS console:

   • Add a manual trigger on the S3 bucket
   • Add a manual trigger on the CloudWatch Log Group
