Azure Network Watcher VNet flow logs filtering is now generally available. You decide which flows get logged based on specific criteria: IP addresses, ports, protocols, encryption state, flow state and traffic direction. Instead of capturing everything and sifting through it later, you log just what your investigation or compliance need requires.
