Start monitoring NetworkManager changes

$ nmcli monitor

nmcli monitor

nmcli monitor watches for and displays NetworkManager events in real-time. It shows changes to network connections, device states, and connectivity status as they occur.
Events displayed include connection activations and deactivations, device state changes (connecting, connected, disconnected), IP address assignments, and overall connectivity state changes.
The command runs continuously until interrupted with Ctrl+C, making it useful for debugging network issues or scripting responses to network events.

Runs in the foreground and blocks the terminal. Only shows events occurring after the monitor starts; historical events are not displayed. For parsing in scripts, consider using nmcli's -t (terse) option for machine-readable output.
