NAME

6       trace-cmd-listen - listen for incoming connection to record tracing.
7

SYNOPSIS

9       trace-cmd listen -p port [OPTIONS]
10

DESCRIPTION

12       The trace-cmd(1) listen sets up a port to listen to waiting for
13       connections from other hosts that run trace-cmd-record(1) with the -N
14       option. When a connection is made, and the remote host sends data, it
15       will create a file called trace.HOST:PORT.dat. Where HOST is the name
16       of the remote host, and PORT is the port that the remote host used to
17       connect with.
18

OPTIONS

20       -p port
21           This option will specify the port to listen to.
22
23       -D
24           This options causes trace-cmd listen to go into a daemon mode and
25           run in the background.
26
27       -V
28           Listen on a vsocket instead. This is useful for tracing between
29           host and guest VMs.
30
31       -d dir
32           This option specifies a directory to write the data files into.
33
34       -o filename
35           This option overrides the default trace in the trace.HOST:PORT.dat
36           that is created when a remote host connects.
37
38       -l filename
39           This option writes the output messages to a log file instead of
40           standard output.
41
42       --verbose[=level]
43           Set the log level. Supported log levels are "none", "critical",
44           "error", "warning", "info", "debug", "all" or their identifiers
45           "0", "1", "2", "3", "4", "5", "6". Setting the log level to
46           specific value enables all logs from that and all previous levels.
47           The level will default to "info" if one is not specified.
48
49               Example: enable all critical, error and warning logs
50
51               trace-cmd listen --verbose=warning
