PCMonitorSuite

PCMonitorSuite is a system for monitoring a computer's hardware diagnostics (temperatures, CPU/GPU usage, memory, etc.), loading data locally and periodically sending it to a REST API server. The project consists of two three components: a Windows application - PCMonitorClient, backend REST API server - PCMonitorServer and html/js web dashboard.

System Architecture

Client Application – PCMonitorClient

• Written in C# (.NET)
• Graphical User Interface made using Windows.Forms libraries
• Runs in the background as a tray icon on the taskbar
• Viewing diagnostics in a separate window
• Local logging to .log file
• Automatic data collection every 10 seconds (using LibreHardwareMonitor),
• Automatic sending JSON data every 10 seconds to PCMonitorServer

REST API Server – PCMonitorServer

• REST API written in Java (Jakarta EE)
• Receives diagnostic data in JSON format
• Storing data in h2 database
• Provides simple endpoints:
  • POST /api/data – receive diagnostic data from the PCMonitorClient
  • GET /api/data – get latest data that came to the server
  • GET /api/data/computers - get all computers
  • GET /api/data/sensor - get all sensors
  • GET /api/data/history?computerId=xx&sensorId=xx - get sensor readings history by computerId and sensorId

Web Dashboard

• Written in html/js
• Selection of computer and sensor for analysis
• Displaying the history of readings of the selected sensor in table, chart format
• Pie chart and bar chart made in chart.js

Build and run

Diagnostic Client

1. Open the PCMonitorClient.sln in Visual Studio.
2. Install required dependencies listed "Requirements" section (for example by NUGet packages in Visual Studio)
3. Build the PCMonitorClient project (Ctrl + Shift + B).
4. Run PCMonitor.exe from bin/Debug or bin/Release.

Server

1. Open the PCMonitorServer project in Apache NetBeans.
2. Run it on a Java EE server (for example: Apache Tomcat 10.1 configured in Apache Netbeans).
3. Ensure the /PCMonitorClient endpoint is available at http://localhost:8080/PCMonitorClient`.

Security (TODO)

• No authentication
• No encryption

---

Planned Features

• Export data to CSV
• System notifications
• Client-server authentication
• Additional configurations in diagnostic client (PCMonitorClient)
• Improvement of web dashboard: add more options for better data visualisation
