udp_port	Monitoring UDP port availability	UDP Port availability	open source monitoring tool open source port monitoring tool monitoring UDP port metrics

UDP is a connectionless transport layer protocol. We determine the availability status of its ports by sending request packets at the application layer and receiving responses. The configuration information requires filling in the hexadecimal content of the application layer packets that prompt responses from the peer. We recommend using Wireshark for packet capture to obtain the transmitted packet content.
You can click on Create UDP Port Availability to configure or select More Actions to import existing configurations.
