Raspberry Pi System Monitor

Real-time dashboard for monitoring Raspberry Pi system metrics
November 2025

Project Overview

For my discovery project, I decided to build a comprehensive system monitoring dashboard using my Raspberry Pi 5. This ambitious undertaking required learning multiple new technologies and overcoming significant networking challenges. The project provides real-time system health monitoring including CPU load, memory usage, and temperature tracking through an intuitive web-based interface hosted locally on the Raspberry Pi. This hands-on experience taught me essential skills in Linux system administration, network configuration, web development with Next.js, and embedded systems deployment.

Technologies Learned & Skills Developed

Next.js TypeScript React Linux SSH Bash Git Raspberry Pi 5 Local Web Hosting

This discovery project required mastering numerous technologies from scratch. Key learning areas included: SSH configuration and remote access to the Raspberry Pi, Linux system administration for network setup and service management, bash scripting for automated system monitoring, Next.js framework for building the web dashboard, IP address management and network troubleshooting, Git version control for project management, and local web hosting on embedded systems. The project provided hands-on experience with the complete development stack from hardware configuration to web application deployment.

System Architecture & Implementation

The monitoring system follows a client-server architecture where the Next.js application runs on the Raspberry Pi itself, reading system metrics directly from the Linux kernel interfaces. Key implementation details include:

Core Monitoring Features

CPU Load Monitoring:
• Real-time CPU utilization tracking across all cores
• Load average calculations (1-min, 5-min, 15-min)
• Process-level CPU usage analysis
• Historical CPU usage trends and graphs

Memory Usage Analysis:
• RAM usage monitoring with available/used breakdowns
• Virtual memory and swap usage tracking
• Memory allocation per process identification
• Low memory threshold alerts and notifications

Temperature Management:
• CPU temperature monitoring with thermal alerts
• GPU temperature tracking for overclocking scenarios
• Historical temperature data for thermal analysis
• Critical temperature warning system implementation

Development Challenges & Problem-Solving

Network Connectivity Issues

I was unable to connect Raspberry Pi to WiFi due to GTother network firewall restrictions. Solved by configuring ethernet connection and understanding network security protocols.

SSH Access Troubleshooting

I failed to establish SSH connection due to incorrect IP address configuration. Resolved through systematic network diagnostics and DHCP lease table analysis.

Hardware Cooling System

Raspberry Pi cooling fan appeared non-functional initially. Discovered the fan only activates after reaching specific CPU temperature thresholds.

Resource Optimization

Implemented efficient data polling mechanisms to prevent overwhelming the Pi's limited resources while maintaining real-time monitoring capabilities.

This project presented numerous real-world challenges that required systematic problem-solving and research. The network configuration issues taught me about enterprise firewall restrictions and alternative connectivity solutions. SSH troubleshooting deepened my understanding of IP addressing and network diagnostics. Hardware integration challenges provided insights into thermal management and embedded system behavior. These obstacles transformed into valuable learning experiences that enhanced my technical problem-solving abilities and system administration skills.
