Class UdpHealthChecker

Namespace

AppHealthMonitor

Assembly

AppHealthMonitor.dll

Checks port health by attempting to send a UDP datagram.

Limitation: UDP is connectionless. A successful send only confirms the local OS accepted the datagram into the send buffer, not that the remote endpoint received it or is alive. This checker will report success even if the target application is down. For reliable health checking, prefer TCP or WebSocket. Use UDP checks only as a supplementary probe alongside other port types.
