The Challenge: Comprehensive System Visibility

The Netdata project addresses a critical infrastructure need: “How can we monitor our entire system in real-time with minimal overhead?” This isn’t just about basic monitoring - it’s about gaining deep insights into system performance, resource usage, and potential issues before they become problems.

📊 What I Built

Netdata provides real-time monitoring capabilities:

  • System Metrics: CPU, memory, disk, and network monitoring
  • Container Monitoring: Docker container performance tracking
  • Custom Dashboards: Tailored monitoring views
  • Alert System: Automated notifications for issues
  • Historical Data: Long-term performance analysis

🛠️ Technical Implementation

Docker Deployment

version: '3.8'
services:
  netdata:
    image: netdata/netdata:latest
    container_name: netdata
    restart: unless-stopped
    ports:
      - "19999:19999"
    volumes:
      - /proc:/host/proc:ro
      - /sys:/host/sys:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
    environment:
      - NETDATA_HOST_IS_CONTAINER=0
