otak-monitor
A lightweight system monitor for VS Code - Track CPU, memory, and disk usage with efficient 5-second updates and 1-minute averages.
Usage
- Find the system monitor in your VS Code status bar
- View CPU usage percentage
- Hover to see detailed current and average metrics
Features
otak-monitor is a lightweight VS Code extension that helps you monitor system resources without leaving your editor.
Key Features
CPU Monitoring:
- Status bar display of CPU usage percentage
- Updates every 5 seconds
- Aggregated across all CPU cores
- Precise to one decimal place
- Current CPU clock speed (MHz)
- 1-minute moving average
Memory Usage Tracking:
- Detailed memory information
- Shows used and total memory in MB
- Memory usage percentage
- 1-minute moving average
- Regular updates
Disk Usage Monitoring:
- Cross-platform disk space monitoring
- Windows: C: drive (home directory in Codespaces)
- macOS: Root volume (/)
- Linux: Root filesystem (workspace root in Codespaces)
- Shows used and total space in GB
- Disk usage percentage
- 1-minute moving average
Visual Integration:
- Clean status bar integration
- Right-aligned placement
- Non-intrusive display
- Detailed hover tooltip showing:
- Current CPU, memory, and disk metrics
- 1-minute average values
- Regular 5-second updates
Requirements
- Visual Studio Code ^1.90.0
- Supported environments:
- Local: Windows, macOS, Linux
- Remote: GitHub Codespaces
Installation
- Install the extension from VS Code Marketplace
- Look for the CPU usage display in your status bar
- Hover over it to see detailed system information
Status Bar Display
The extension shows the following information in your status bar:
CPU: 45.3% // CPU usage
With a detailed tooltip showing:
Current:
CPU Usage: 45.3% (2400 MHz)
Memory Usage: 1024 MB / 2048 MB (50.0%)
Disk Usage: 150 GB / 500 GB (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 12 data points (5-second intervals over 1 minute)
- Updates occur every 5 seconds 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
