NAME

       trace-cmd-listen - listen for incoming connection to record tracing.

SYNOPSIS

       trace-cmd listen -p port [OPTIONS]

DESCRIPTION

       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.

OPTIONS

       -p port
           This option will specify the port to listen to.

       -D
           This options causes trace-cmd listen to go into a daemon mode and run in the
           background.

       -V
           Listen on a vsocket instead. This is useful for tracing between host and guest VMs.

       -d dir
           This option specifies a directory to write the data files into.

       -o filename
           This option overrides the default trace in the trace.HOST:PORT.dat that is created
           when a remote host connects.

       -l filename
           This option writes the output messages to a log file instead of standard output.

       --verbose[=level]
           Set the log level. Supported log levels are "none", "critical", "error", "warning",
           "info", "debug", "all" or their identifiers "0", "1", "2", "3", "4", "5", "6". Setting
           the log level to specific value enables all logs from that and all previous levels.
           The level will default to "info" if one is not specified.

               Example: enable all critical, error and warning logs

               trace-cmd listen --verbose=warning
