Network Monitoring for Beginners: Getting Started with TPG stack Workshop

This repository contains the necessary files and instructions that will used for NAF (network automation forum) 2024 workshop on collecting metrics from network devices using the Telegraf, Prometheus, and Grafana (TPG) stack.

Note: clab.yaml file and device configs were taken from one of the sr-labs repository https://github.com/srl-labs/srl-telemetry-lab

Overview

Learn how to collect, store, and visualize network metrics using:

• Telegraf: Data collection agent
• Prometheus: Time series database and monitoring system
• Grafana: Visualization and analytics platform

Workshop Demo

1. Click on "Create Codespaces on main" to launch a development environment

2. Network Simulation Setup

We use ContainerLab to simulate the network environment.

# Deploy the network topology
sudo containerlab deploy -t clab.yaml

3. TPG Stack Deployment

Deploy the monitoring stack using Docker Compose:

# Start the TPG stack
docker compose -f docker-compose-sample.yaml up

4. Port Configuration

To access the various UIs, configure the following ports in VS Code's ports section:

Service	Port	Description
Prometheus	9090	Metrics storage and querying
Alert Manager	9093	Alerting interface
Grafana	3000	Visualization dashboard
