iTermSysMon

iTermSysMon is a lightweight macOS system monitor that operates as a web panel within iTerm2, offering users a comprehensive overview of system metrics.

Key Features

• Resource Monitoring: Track CPU, memory, GPU, network usage, open ports, and file activity, providing essential insights into system performance.
• Process Management: View application and process usage to identify resource-heavy tasks.
• Customizable Disk Monitoring: Configure disk usage monitoring with adjustable scan intervals for various folders, including temporary, cache, and build directories.
• Network Traffic Monitoring: Set specific intervals for tracking process-network activity, allowing for detailed analysis of network resource utilization.
• Data Export: Easily export monitored data in CSV format for further analysis or tracking.

Watched Folders Configuration

Users can modify watched_folders.json to manage which folders to monitor, adjusting the scan interval to their preference—ranging from 1 minute to several days. The last scan details, including time and folder sizes, are saved, ensuring efficiency by avoiding unnecessary rescans upon restarting iTerm2. The monitor is designed to avoid nested duplicate scans, enhancing performance. A feature to highlight folders exceeding 5 GB assists in identifying large storage consumers.

Network Sampling Control

Process-traffic sampling can be set between 1 to 60 seconds or minutes. The default interval is set to 10 seconds, allowing users to effectively track resource utilization.

File activity monitoring functions without the need for administrative access, although tracking process names for file activity may require an optional sudoers rule for using fs_usage.

This project streamlines the ability to monitor system performance directly within iTerm2, making it a valuable tool for developers and system administrators alike.
