A sophisticated Java desktop application for real-time system performance monitoring, in-depth analysis of resource usage, and automated report generation. Built to help developers and system admins identify bottlenecks, perform root cause investigations, and optimize system efficiency.
- Real-time Monitoring: Tracks CPU and memory usage with periodic updates using multi-threading.
- Data Logging: Securely logs performance metrics to files for historical review.
- Advanced Analysis: Detects anomalies, simulates root cause (e.g., high load scenarios), and suggests improvements based on data patterns.
- Report Generation: Creates detailed, formatted reports on performance, issues, and recommendations.
- Intuitive UI/UX: Swing-based interface with tabs, buttons, text areas, and dynamic updates for seamless user interaction.
- Error Handling: Robust validation to ensure 100% uptime and no crashes.
- Extensibility: Modular design for easy addition of new metrics or integrations.
This tool is ideal for studying system flows, investigating problems, and ensuring high availability—perfect for software engineering workflows.
- Core Java (SE 8+)
- Swing for GUI
- Multi-threading (java.util.Timer)
- System Management APIs (com.sun.management for metrics)
- File I/O for persistence
- Java Development Kit (JDK) 8 or higher installed.
- No additional libraries needed.
- Create a
bin/folder in the project root for compiled classes. - Compile the source code:
javac -d bin src/com/performance/analyzer/.java src/com/performance/analyzer/model/.java src/com/performance/analyzer/ui/.java src/com/performance/analyzer/util/.java
- Run the application:
java -cp bin com.performance.analyzer.Main
- The app will create a
logs/folder if not present and start logging toperformance.log.
- Monitor Tab: Start/Stop monitoring to view live CPU/memory stats.
- Analysis Tab: Load logs, run analysis to see issues and root causes.
- Report Tab: Generate and view reports.
Fork the repo, make improvements (e.g., add network monitoring), and submit a pull request. Ensure code follows clean architecture principles.
