System Monitor Pro — Short Overview

A small Java project with a Python launcher. This file can be used for presentations or as a README.

Short Description

A Swing application that displays mock system samples (CPU, Memory, Disk, Temperature, Network), calculates averages, and exports them to a CSV file. A Python launcher helps compile/run the app and logs launch timestamps.

Project Structure (Quick Functional View)

Java Application

• src/main/java/svc/Main.java — GUI entry point (svc.Main)

• src/main/java/svc/MainFrame.java — Main window and UI (svc.MainFrame)

• src/main/java/svc/SystemMonitor.java — Periodic sample generation (svc.SystemMonitor)

  • Includes inner class SystemSample

• src/main/java/svc/MetricsCollector.java — Sample aggregation and analysis

• src/main/java/svc/UIUtils.java — UI helper components (buttons, progress bars, formatting)

• src/main/java/svc/CsvExporter.java — Export averaged metrics to CSV and summary file

Python Launcher & Logs

• python/app.py — Java compile/run launcher and startup logger

  • Contains important constants such as MAIN_CLASS, JAVA_SRC_DIR, BUILD_DIR

• python/launcher_history.jsonl — Timestamp log of each launch

Configuration

• .gitignore — Ignores build output, logs, and temporary files

How It Works (Concise Flow)

1. The Python launcher records the launch time in launcher_history.jsonl.

2. If javac is available, app.py compiles all .java files from JAVA_SRC_DIR into BUILD_DIR.

3. The launcher starts the Java app using:

   java -cp out svc.Main

4. The UI (MainFrame) displays mock system samples generated by SystemMonitor and stores them in MetricsCollector.

5. The user can export the current snapshot via CsvExporter to a CSV file (default: export_history.csv).

Quick Run Commands

Using the Python Launcher (recommended)

python python/app.py

Manual Compile & Run (Unix-like)

javac -d out $(find src/main/java -name '*.java')
java -cp out svc.Main

(On Windows, list all .java files explicitly in the javac command.)

Key Points for Presentation

• Clear separation of concerns:

  • Sampling → SystemMonitor
  • Aggregation/Analysis → MetricsCollector
  • UI → MainFrame / UIUtils
  • Export → CsvExporter

• Python launcher allows running the project without an IDE and keeps a launch history.

• CSV output contains averaged metrics and can be opened in Excel or other analysis tools.
