TRACE-CMD-LISTEN(1)         libtracefs Manual        TRACE-CMD-LISTEN(1)

NAME         top

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

SYNOPSIS         top

       trace-cmd listen -p port [OPTIONS]

DESCRIPTION         top

       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         top

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

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

           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

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

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

           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
