Le check système n’inclut aucun événement.
Le check système n’inclut aucun check de service.
Le tag host:<HOSTNAME> est automatiquement appliqué à l’ensemble des métriques système. En outre, le tag device:<NOM_APPAREIL> est appliqué aux espaces de nommage suivants :
system.disk.*system.fs.inodes.*system.io.*system.net.*Ce check recueille le nombre de cœurs du processeur sur un host ainsi que les temps processeur (système, utilisateur, inactivité, etc.).
Le check System Core est inclus avec le paquet de l'Agent Datadog. Vous n’avez donc rien à installer sur votre serveur.
Modifiez le fichier system_core.d/conf.yaml dans le dossier conf.d/ à la racine du répertoire de configuration de votre Agent. Consultez le fichier d’exemple system_core.d/conf.yaml pour découvrir toutes les options de configuration disponibles. Remarque : au moins une entrée est requise dans instances pour activer le check. Exemple :
init_config:
instances:
- foo: bar
Lancez la sous-commande status de l’Agent et cherchez system_core dans la section Checks.
|
system.core.count (gauge) |

|
system.core.idle (gauge) |

Selon la plateforme, le check peut recueillir d’autres métriques de temps processeur, p. ex. system.core.interrupt sous Windows, system.core.iowait sous Linux, etc.
Le check System Core n’inclut aucun événement.
Le check System Core n’inclut aucun check de service.
Ce check surveille le nombre d’octets entrants et sortants du swap sur le système.
Le check System Swap est inclus avec le paquet de l'Agent Datadog. Vous n’avez donc rien à installer sur votre serveur.
Modifiez le fichier system_swap.d/conf.yaml dans le dossier conf.d/ à la racine du répertoire de configuration de votre Agent. Consultez le fichier d’exemple system_swap.d/conf.yaml pour découvrir toutes les options de configuration disponibles. Remarque : aucune configuration initiale n’est possible pour ce check.
Lancez la sous-commande status de l’Agent et cherchez system_swap dans la section Checks.
