network.transport

Stableenumas of v1.44.0

OSI transport layer or inter-process communication method.

The value SHOULD be normalized to lowercase.

Consider always setting the transport when setting a port number, since a port number is ambiguous without knowing the transport. For example different processes could be listening on TCP port 12345 and UDP port 12345.
