3. Hover over it to see detailed system information
4. Click to copy current metrics in Markdown format

Status Bar Display

The extension shows the following information in your status bar:

CPU: 45.3%  // CPU usage

Hover over the status bar to see detailed information:

Current:

---

CPU Usage: 45.3% (2400 MHz)
Memory Usage: 1024 MB / 2048 MB (50.0%)
Disk Usage: 150 GB / 500 GB (30.0%)

# System Metrics (2024-02-24 14:00:00)

## Current Status
- **CPU Usage:** 45.3% @ 2400 MHz
- **Memory Usage:** 1024 MB / 2048 MB (50.0%)
- **Disk Usage (C:):** 150 GB / 500 GB (30.0%)

## 1-Minute Average
- **CPU:** 44.8%
- **Memory:** 49.5%
- **Disk:** 30.0%

Note: For disk usage, the monitored path varies by environment:

• Windows:
  • Local: C: drive
  • Codespaces: Home directory
• macOS: Root volume (/)
• Linux:
  • Local: Root filesystem (/)
  • Codespaces: Workspace root

Implementation Details

• CPU usage is calculated by comparing idle and total CPU time differences
• Memory values are shown in MB and percentage
• Disk usage monitoring adapts to the environment:
  • Local machines: Monitors system root or C: drive
  • Codespaces: Monitors relevant workspace paths
• Moving averages are calculated using 24 data points (2.5-second intervals over 1 minute)
• Updates occur every 2.5 seconds (5 seconds when window is not focused) for efficient monitoring
• Minimal performance impact on the system

GitHub Codespaces Support

The extension automatically detects when running in GitHub Codespaces and adjusts its behavior:

• Monitors the workspace root directory in Linux environments
• Uses home directory for Windows-based Codespaces
• Maintains consistent monitoring experience across all environments
• Provides accurate disk usage information for containerized development
