trace-cmd-listen - listen for incoming connection to record tracing.
trace-cmd listen -p port [OPTIONS]
The trace-cmd(1) listen sets up a port to listen to waiting for connections from other hosts that run trace-cmd-record(1) with the -N option. When a connection is made, and the remote host sends data, it will create a file called trace.HOST:PORT.dat. Where HOST is the name of the remote host, and PORT is the port that the remote host used to connect with.
Example: enable all critical, error and warning logs
trace-cmd listen --verbose=warning
