AWS NAT Gateway

개요

AWS NAT Gatewy를 이용해 인터넷에서 먼저 인스턴스와 연결하는 것을 방지하면서 프라이빗 서브넷에 있는 인스턴스를 인터넷에 연결할 수 있습니다.

이 통합을 활성화하면 Datadog에서 모든 NAT Gateway 메트릭을 확인할 수 있습니다.

설정

설치

아직 설정하지 않은 경우 먼저 Amazon Web Services 통합을 설정하세요.

메트릭 수집

  1. AWS 통합 페이지의 Metric Collection 탭에서 NATGateway가 활성화되어 있는지 확인합니다.
  2. Datadog - AWS NAT Gateway 통합을 설치하세요.

로그 수집

로깅 활성화

S3 버킷이나 CloudWatch로 로그를 전송하도록 AWS NAT Gateway를 구성하세요.

참고: S3 버킷에 로깅하는 경우 amazon_nat_gateway가 _Target prefix_로 지정되어야 합니다.

Datadog에 로그 전송

  1. 아직 설정하지 않은 경우 Datadog Forwarder Lambda 함수를 설정하세요.

  2. Lambda 함수를 설치한 후 AWS 콘솔에서 AWS NAT Gateway 로그를 포함하는 S3 버킷이나 CloudWatch 로그 그룹에 수동으로 트리거를 추가하세요.
