.SH NAME
|
|
dbus\-monitor \- debug probe to print message bus messages
|
|
.SH SYNOPSIS
|
|
.PP
|
|
.B dbus\-monitor
|
|
[\-\-system | \-\-session | \-\-address ADDRESS] [\-\-profile | \-\-monitor]
|
|
[watch expressions]
|
|

|
.SH DESCRIPTION
|
|
|
|
The \fIdbus\-monitor\fP command is used to monitor messages going
|
|
through a D\-Bus message bus. See
|
|
http://www.freedesktop.org/software/dbus/ for more information about
|
|
the big picture.
|
|
|
|
.PP
|
|
There are two well\-known message buses: the systemwide message bus
|
|
(installed on many systems as the "messagebus" service) and the
|
|
per\-user\-login\-session message bus (started each time a user logs in).
|
|
The \-\-system and \-\-session options direct \fIdbus\-monitor\fP to
|
|
monitor the system or session buses respectively. If neither is
|
|
specified, \fIdbus\-monitor\fP monitors the session bus.
|
|
|
|
.PP
|
|
\fIdbus\-monitor\fP has two different output modes, the 'classic'\-style
|
|
monitoring mode and profiling mode. The profiling format is a compact
|
|
format with a single line per message and microsecond\-resolution timing
|
|
information. The \-\-profile and \-\-monitor options select the profiling
|
|
and monitoring output format respectively. If neither is specified,
|
|
\fIdbus\-monitor\fP uses the monitoring output format.
|
|
|
|
.PP
|
|
In order to get \fIdbus\-monitor\fP to see the messages you are interested
|
|
in, you should specify a set of watch expressions as you would expect to
|
|
be passed to the \fIdbus_bus_add_match\fP function.
|
|
|
|
.PP
|
|
The message bus configuration may keep \fIdbus\-monitor\fP from seeing
|
|
all messages, especially if you run the monitor as a non\-root user.
|
|
|
|
