Episode 122: Performance Metrics, Sensors, and SNMP Basics

Monitoring network health begins with knowing what to measure—and how. In this episode, we cover the essential performance metrics that indicate how well a network is functioning, including bandwidth usage, latency, jitter, packet loss, and error rates. You’ll learn what thresholds are considered acceptable and how performance metrics help predict or detect problems before users notice.We also introduce SNMP (Simple Network Management Protocol) and how it enables communication between devices and monitoring platforms. We explain SNMP versions, how MIBs work, and how sensors and agents collect performance data. These tools form the backbone of network monitoring systems, enabling alerts, dashboards, and proactive support. Mastering this material is essential for both the exam and real-time operations.
