5Managing, monitoring, and troubleshooting network operations

• 5.1Logging/monitoring and connectivity troubleshooting

  Understand logging of network components with Google Cloud Observability (Cloud VPN/Cloud Router/VPC Service Controls/Cloud NGFW/Firewall Insights/VPC Flow Logs/Cloud DNS/Cloud NAT/Network Connectivity Center), monitoring networking metrics, draining/redirecting traffic with the Application Load Balancer, troubleshooting VPN/Interconnect/Cloud Router BGP, and investigating with VPC Flow Logs/firewall logs/Packet Mirroring.

• 5.2Network Intelligence Center

  Understand monitoring/troubleshooting with Network Intelligence Center: Network Topology (visualize throughput and traffic flows), Connectivity Tests (diagnose route/firewall misconfigurations), Performance Dashboard (packet loss and latency: Google-wide/project-scoped), Firewall Insights (monitor/improve rules), Network Analyzer (auto-detect failures/suboptimal configs/utilization warnings), and Flow Analyzer (evaluate traffic via VPC Flow Logs).
