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