Perfmon – Consolidate your favorite CLI monitoring tools into a single TUI

Summary

Traditional performance monitors often overwhelm users with information or lack the flexibility to show exactly what you need. Perfmon solves this by providing: Consolidation: View output from multiple diagnostic tools (like top, vmstat, netstat) in one place. Focus: A clean, tabbed interface lets you switch between different metrics without terminal clutter. Visibility: Real-time sparklines provide an immediate "at-a-glance" health check of your system's core resources. Flexibility: Don't like the defaults? Bring your own shell commands via a simple TOML file. 🚀 Blazing Fast: Written in Go with minimal CPU and memory overhead. 📂 Tabbed Navigation: Organize your monitoring tools into logical, navigable views. 📈 Live Sparklines: Visual summaries for Load, CPU, Memory, and Network. 🎨 Adaptive Themes: Seamlessly toggle between Light and Dark modes. ⚙️ Deeply Configurable: Custom commands, refresh intervals, and environment-specific settings. 🐧 Cross-Platform: Intelligent defaults for both Linux and macOS.
