7 dbus-monitor \- debug probe to print message bus messages
11 [\-\-system | \-\-session | \-\-address ADDRESS] [\-\-profile | \-\-monitor]
16 The \fIdbus-monitor\fP command is used to monitor messages going
17 through a D-Bus message bus. See
18 http://www.freedesktop.org/software/dbus/ for more information about
22 There are two well-known message buses: the systemwide message bus
23 (installed on many systems as the "messagebus" service) and the
24 per-user-login-session message bus (started each time a user logs in).
25 The \-\-system and \-\-session options direct \fIdbus-monitor\fP to
26 monitor the system or session buses respectively. If neither is
27 specified, \fIdbus-monitor\fP monitors the session bus.
30 \fIdbus-monitor\fP has two different output modes, the 'classic'-style
31 monitoring mode and profiling mode. The profiling format is a compact
32 format with a single line per message and microsecond-resolution timing
33 information. The \-\-profile and \-\-monitor options select the profiling
34 and monitoring output format respectively. If neither is specified,
35 \fIdbus-monitor\fP uses the monitoring output format.
38 In order to get \fIdbus-monitor\fP to see the messages you are interested
39 in, you should specify a set of watch expressions as you would expect to
40 be passed to the \fIdbus_bus_add_match\fP function.
43 The message bus configuration may keep \fIdbus-monitor\fP from seeing
44 all messages, especially if you run the monitor as a non-root user.
49 Monitor the system message bus.
52 Monitor the session message bus. (This is the default.)
54 .I "--address ADDRESS"
55 Monitor an arbitrary message bus given at ADDRESS.
58 Use the profiling output format.
61 Use the monitoring output format. (This is the default.)
64 Here is an example of using dbus-monitor to watch for the gnome typing
68 dbus-monitor "type='signal',sender='org.gnome.TypingMonitor',interface='org.gnome.TypingMonitor'"
73 dbus-monitor was written by Philip Blundell.
74 The profiling output mode was added by Olli Salli.
