📤 UDP Port Monitor
The UDP monitor sends a UDP packet to a host:port and optionally checks for a response.
🎯 Что делает
- 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

⚠️ Важное замечание
warning
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.
