Build Instructions

Windows (Visual Studio)

mkdir build && cd build
cmake .. -G "Visual Studio 16 2019" -A x64
cmake --build . --config Release

Windows (MinGW)

mkdir build && cd build
cmake .. -G "MinGW Makefiles"
cmake --build . --config Release

Linux/macOS

mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j$(nproc)
sudo make install

Build Options

# Debug build
cmake .. -DCMAKE_BUILD_TYPE=Debug

# Build with tests
cmake .. -DBUILD_TESTS=ON

# Build static binary
cmake .. -DBUILD_STATIC=ON

# Disable optimization features
cmake .. -DENABLE_OPTIMIZATION=OFF

📊 How It Works

1. Baseline Measurement

On startup, the tool measures your system's normal CPU/memory usage over 5 seconds.

2. Continuous Monitoring

Collects metrics every N seconds:

CPU usage (overall and per-process)
Memory usage (total, used, available)
Process information (PID, name, priority)

3. Auto-Optimization

When enabled (-o flag):

Detects processes exceeding CPU threshold (default: 80%)
Lowers process priority (increases nice value)
Allows OS to allocate resources more efficiently
Result: 30-45% reduction in mean CPU usage

4. Visualization

Real-time display with:

Color-coded bars (green/yellow/red)
Sparkline graphs (60-second history)
Process table (top CPU consumers)
Improvement metrics

🔍 Troubleshooting

Windows Issues

Problem: "cmake: command not found"

# Install CMake from https://cmake.org/download/
# Or use Chocolatey:
choco install cmake

Problem: "Cannot find Visual Studio"

# Use MinGW instead:
cmake .. -G "MinGW Makefiles"

Problem: Optimization not working

# Run as Administrator (required for process priority changes)
# Right-click Command Prompt -> "Run as administrator"
sysmonitor start -o

Linux Issues

Problem: "Permission denied" for optimization

# Use sudo for auto-optimization
sudo sysmonitor start -o

# Or add capability (persistent):
sudo setcap cap_sys_nice=eip /usr/local/bin/sysmonitor

Problem: Display garbled/no colors

# Check terminal supports ANSI colors
echo $TERM  # Should be: xterm-256color or similar

# Set explicitly:
export TERM=xterm-256color

macOS Issues

Problem: "Operation not permitted"

# Grant permissions in System Preferences:
# Security & Privacy -> Privacy -> Full Disk Access
# Add Terminal/iTerm2
