L’inspection des évènements Docker permet de détecter les containers dont les fréquences d’exécution des healthchecks est trop aggressive.

Pour détecter l’exécution des commandes healthcheck de vos containers, il convient de filtrer les évènements avec le filtre exec_start :

$ docker system events --filter event=exec_start
