Extraits du modèle Amazon CloudWatch Logs
Amazon CloudWatch Logs peut surveiller votre système, votre application et vos fichiers journaux personnalisés à partir d' EC2 instances Amazon ou d'autres sources. Vous pouvez l'utiliser AWS CloudFormation pour configurer et gérer des groupes de journaux et des filtres métriques. Pour plus d'informations sur Amazon CloudWatch Logs, consultez le guide de l'utilisateur Amazon CloudWatch Logs.
Rubriques
Envoyer des journaux à CloudWatch Logs depuis une instance Linux
Le modèle suivant explique comment configurer un serveur Web sur Amazon Linux 2023 avec l'intégration CloudWatch des journaux. Le modèle exécute les tâches suivantes :
-
Installe Apache et PHP.
-
Configure l' CloudWatch agent pour transférer les journaux d'accès Apache vers CloudWatch Logs.
-
Configure un rôle IAM pour permettre à l' CloudWatch agent d'envoyer des données de journal à CloudWatch Logs.
-
Crée des alarmes et des notifications personnalisées pour surveiller les erreurs 404 ou l'utilisation élevée de la bande passante.
Les événements du journal provenant du serveur Web fournissent des données métriques pour les CloudWatch alarmes. Les deux filtres métriques décrivent comment les informations du journal sont transformées en CloudWatch métriques. La métrique 404 compte le nombre d'erreurs 404. La métrique de taille analyse la taille d'une requête. Les deux CloudWatch alarmes enverront des notifications s'il y a plus de deux 404 dans les 2 minutes ou si la taille moyenne des demandes est supérieure à 3 500 Ko en 10 minutes.

Envoyer des journaux vers CloudWatch Logs à partir d'une instance Windows
Le modèle suivant configure les CloudWatch journaux pour une instance Windows 2012R2.
L'agent CloudWatch Logs sous Windows (agent SSM sous Windows 2012R2 et Windows 2016 AMIs) envoie des journaux uniquement après son démarrage, de sorte que les journaux générés avant le démarrage ne sont pas envoyés. Pour contourner ce problème, le modèle permet de s'assurer que l'agent démarre avant que les journaux ne soient écrits par :
-
Configuration de l'agent défini comme premier
configélément de cfn-initconfigSets. -
Utilisation de
waitAfterCompletionpour insérer une pause après la commande qui démarre l'agent.
