3- Network Monitoring and Troubleshooting

Monitoring is essential for managing and maintaining network infrastructure. It gives visibility into device health and application behavior and plays a key role in detecting faults, troubleshooting performance issues, and responding to risks more effectively.

As networks grow in size and complexity—often spanning multiple domains and technologies—manual monitoring and troubleshooting become increasingly impractical. A good monitoring system helps by continuously checking the network’s status, spotting unusual behavior, and identifying risks before they cause real problems. It should also support performance tracking, capacity management, and ensure service-level agreements (SLAs) are met.

When monitoring is combined with automation, it becomes even more powerful. Automated responses help reduce manual effort, speed up reaction times, and maintain consistency. They also enable handling problems outside of business hours, which is critical in large, always-on environments.

The ETSI GR ENI 049 document defines procedures and capability levels for systems that enable automated monitoring, issue detection, and troubleshooting in intent-based networks. We will evaluate these capabilities in detail throughout the coming tests.
