UDP Metrics:

 

UDP Datagrams Delivered to UDP users - The number of UDP datagrams delivered to UDP users

UDP Datagrams Failed to be Delivered to UDP users - The number of received UDP datagrams that could not be delivered for reasons other than the lack of an application at the destination port

UDP Datagrams Sent - Total number of UDP datagrams sent from this entity

UDP Datagrams Lost Due to No Room in Receive Buffer - Total number of UDP datagrams lost because there was no room in the receive buffer
