Crawler Crawler

Présentation

Utilisez les passerelles NAT Amazon pour autoriser les instances d’un sous-réseau privé à se connecter à Internet, mais empêcher Internet de lancer une connexion avec ces instances.

Activez cette intégration pour visualiser dans Datadog toutes vos métriques de passerelles NAT.

Implémentation

Installation

Si vous ne l’avez pas déjà fait, configurez d’abord l’intégration Amazon Web Services.

Collecte de métriques

  1. Dans le carré d’intégration AWS, assurez-vous que l’option NATGateway est cochée dans la section concernant la collecte des métriques.

  2. Installez l’intégration Datadog/Amazon NAT Gateway.

Collecte de logs

Activer le logging

Configurez Amazon NAT Gateway de façon à ce que ses logs soient envoyés vers un compartiment S3 ou vers Cloudwatch.

Remarque : si vous envoyez vos logs vers un compartiment S3, assurez-vous que amazon_nat_gateway est défini en tant que Target prefix.

Envoyer des logs à Datadog

  1. Si vous ne l’avez pas déjà fait, configurez la fonction Lambda de collecte de logs AWS avec Datadog.
  2. Une fois la fonction Lambda installée, ajoutez manuellement un déclencheur sur le compartiment S3 ou sur le groupe de logs Cloudwatch qui contient vos logs Amazon NAT Gateway dans la console AWS :
