Journalisation et journalisation d'audit (LOG et AL)

Les journaux d'audit Logging et Audit Logging (LOG et AL) de l'appareil Google Distributed Cloud (GDC) avec air gap vous permettent de suivre les opérations d'administration et d'accès aux données pour les pipelines de journalisation et de surveillance dans les charges de travail racine et d'organisation. Les journaux d'audit Kubernetes et l'enregistreur d'audit d'observabilité enregistrent l'identité de l'utilisateur ou du service, la ressource cible et les champs de charge utile JSON pour les ressources personnalisées LoggingTarget, AuditLoggingTarget, LoggingRule et ObservabilityPipeline, ainsi que pour les requêtes Loki et Prometheus.
