# 🖥️ monitor
|
||||
|
||||
**monitor** ist ein leichtgewichtiges Monitoring-Tool, das mehrere Systeme per **Ping** überwacht und die Ergebnisse in einer **statischen HTML-Webseite** anzeigt.
|
||||
Ideal für kleine Netzwerke, Homelabs oder interne Statusseiten.
|
||||
|
||||
---
|
||||
|
||||
## 🚀 Features
|
||||
|
||||
- Überwacht beliebig viele Hosts per **ICMP-Ping**
|
||||
- Generiert automatisch eine **statische HTML-Statusseite**
|
||||
- Anzeige von:
|
||||
- Antwortzeit (ms)
|
||||
- Online-/Offline-Status
|
||||
- Letztem Check-Zeitpunkt
|
||||
- Einfache Konfiguration über JSON oder YAML
|
||||
- Keine Datenbank, kein Serverprozess – alles rein statisch
|
||||
- Optional: automatischer Refresh der Webseite
