Key monitoring metrics
Availability: is the device online. Bandwidth utilization: link usage. Latency: packet transit time. Error rate: CRC, loss, collisions, etc. Device health: CPU, memory, temperature.
Network monitoring best practices
Proactive monitoring: do not just rely on alerts — track trends too. Protocol-level monitoring: NetFlow, sFlow, SNMP. Anomaly detection: spot behavior that drifts from baseline. Context correlation: tie network events to business and services. Key advantages: full network visibility, proactive issue discovery, fast root-cause analysis, and performance-tuning suggestions.
