Network Operations

Documentation, monitoring, performance metrics, and disaster-recovery concepts that keep networks running.

Good operations depend on documentation: physical and logical network diagrams, IP address management (IPAM), asset inventories, rack diagrams, and baselines. Change and configuration management keep these current.

Monitoring uses SNMP (polls and traps), Syslog (centralized logging with severity levels), NetFlow/sFlow (traffic analysis), and performance metrics — bandwidth, latency, jitter, and packet loss. Establishing a baseline lets you spot anomalies, and log aggregation supports both troubleshooting and security.

Which protocol centralizes event/log messages from many devices to one collector?

Why establish a performance baseline?
