📤 UDP Port Monitor
The UDP monitor sends a UDP packet to a host:port and optionally checks for a response.
🎯 Que Hace
- Sends a UDP datagram to the target host and port
- Optionally sends custom data
- Optionally checks for expected data in the response
- Measures response time
⚙️ Configuracion
| Configuracion | Descripcion | Ejemplo |
|---|---|---|
| Name | A friendly name | DNS Server UDP |
| Host / IP | Target hostname or IP | 10.0.0.2 |
| Port | UDP port number | 53 |
| Send Data | Data to send | (optional) |
| Expect Data | Expected response | (optional) |
⚠️ Nota Importante
aviso
UDP is connectionless. Unlike TCP, UDP doesn't establish a connection. If the target doesn't respond, it might mean the port is open but the service doesn't send replies, OR the port is closed. UDP monitoring is inherently less reliable than TCP monitoring for this reason.
💡 Cuando Usar
- Game servers (many use UDP)
- VoIP services
- DNS servers (port 53)
- Custom UDP-based protocols
