Modern Network Telemetry

This course is designed for network engineers looking to gain practical, hands-on experience with modern network telemetry and observability tools. You'll learn how to collect, store, and visualize real-time network data using open-source platforms like Prometheus, Telegraf, and Grafana.

We’ll guide you through the complete telemetry stack — from understanding core concepts to configuring collectors, analyzing metrics, and building insightful dashboards.

What you will learn:

• Understand the fundamentals of network telemetry and how it compares to traditional monitoring solutions.
• Explore the benefits and use cases of model-driven telemetry in modern networks.
• Collect telemetry data using Telegraf with plugins for SNMP, ICMP, execd, and gNMI.
• Work with gNMIc for gNMI-based telemetry collection.
• Store and query metrics using Prometheus and its time series data model.
• Master key Prometheus functions like rate(), irate(), and increase(), along with label filtering and range selection.
• Visualize telemetry data using Grafana, building dashboards for real-time network observability.
• Gain confidence in deploying a full telemetry stack in real-world network environments.
