You cannot fix what you cannot see. Network monitoring gives you visibility so you can detect problems before users complain.
I'll cover these monitoring concepts:
- SNMP for device management data
- NetFlow and sFlow for traffic analysis
- Syslog for centralized logging
- Performance metrics like latency and jitter
- Alerting and threshold configuration
- Popular monitoring tools
- Dashboards for visualization
By the end, you'll know how to build monitoring that tells you what is happening on your network at any moment.
