Network Security Groups (NSGs): Focus on controlling traffic flow, not directly providing performance metrics.
Network Flow Logs: While capturing traffic information, they need processing and analysis for performance insights and aren,t real-time.
Inter-Region Latency: Measures latency between specific OCI regions, not general network performance across your resources.
Network Monitoring Service: Offers comprehensive real-time monitoring capabilities:
Metrics collection: Gathers key performance metrics like bandwidth usage, packet loss, and latency from various network resources.
Real-time dashboards: Visualizes collected metrics in real-time, allowing you to track network health and identify performance issues as they occur.
Alerting and notifications: Set up alerts based on metric thresholds to receive proactive notifications about potential problems.
Historical data analysis: Analyze historical trends in collected metrics to gain insights into network behavior and performance over time.
