About:
Nagstamon is a cross-platform, open-source status monitor that connects to Nagios, Icinga, and similar monitoring systems. It provides a floating, always-on-top status bar in the system tray, offering real-time visibility into host and service states. This allows system administrators to quickly detect and respond to infrastructure issues without constantly checking a web dashboard.
Key Features:
  • Real-time monitoring of Nagios, Icinga, and other monitoring systems
  • Floating, always-on-top status bar and system tray integration
  • Supports multiple monitoring servers simultaneously
  • Desktop notifications and sound alerts for critical issues
  • Cross-platform support (macOS, Windows, Linux)
Use Cases:
  • System administrators monitoring production infrastructure health
  • DevOps teams tracking service availability across multiple environments
  • Network engineers overseeing distributed system performance
Alternatives:
  • Nagios Core Web UI – Nagstamon provides desktop notifications and persistent status visibility instead of requiring constant browser access
  • Check_MK – Nagstamon is a lightweight client-side monitor rather than a full monitoring platform
