Gli audit log del Domain Name System (DNS) in Google Distributed Cloud (GDC) con air gap registrano gli aggiornamenti delle zone CoreDNS insieme agli eventi di creazione di ManagedDNSZone e ResourceRecordSet. Questo documento elenca le operazioni controllate, i campi dei metadati e gli esempi di payload JSON degli audit log di Kubernetes per i workload root e dell'organizzazione.
