• Rename net.peer.*, net.host.*, and net.sock.* attributes to align with ECS (#3402) BREAKING: rename net.peer.name to server.address on client side and to client.address on server side, net.peer.port to server.port on client side and to client.port on server side, net.host.name and net.host.port to server.name and server.port (since net.host.* attributes only applied to server instrumentation) net.sock.peer.addr to server.socket.address on client side and to client.socket.address on server side, net.sock.peer.port to server.socket.port on client side and to client.socket.port on server side, net.sock.peer.name to server.socket.domain (since net.sock.peer.name only applied to client instrumentation), net.sock.host.addr to server.socket.address (since net.sock.host.* only applied to server instrumentation), net.sock.host.port to server.socket.port (similarly since net.sock.host.* only applied to server instrumentation), http.client_ip to client.address
• BREAKING: Introduce network.transport defined as OSI Transport Layer or Inter-process Communication method. Introduce network.type defined as OSI Network Layer or non-OSI equivalent.
