GKE Logs

Jan 1, 0001

Definition

GKE Logs refer to the logging capabilities provided by Google Kubernetes Engine (GKE) that capture and store logs from various components of a Kubernetes cluster, including system logs, application logs, and audit logs. These logs are essential for monitoring, troubleshooting, and securing Kubernetes workloads. GKE integrates with Google Cloud’s operations suite, allowing users to view and analyze logs through Cloud Logging, which provides centralized log management and analysis tools.
