NAME
dbus-monitor - debug probe to print message bus messages
SYNOPSIS
dbus-monitor [--system | --session | --address ADDRESS] [--profile |
--monitor] [watch expressions]
DESCRIPTION
The dbus-monitor 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.
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 dbus-monitor to monitor the sys-
tem or session buses respectively. If neither is specified, dbus-moni-
tor monitors the session bus.
dbus-monitor has two different output modes, the 'classic'-style moni-
toring mode and profiling mode. The profiling format is a compact for-
mat 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,
dbus-monitor uses the monitoring output format.
In order to get dbus-monitor 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 dbus_bus_add_match function.
The message bus configuration may keep dbus-monitor from seeing all
messages, especially if you run the monitor as a non-root user.
OPTIONS
--system
Monitor the system message bus.
--session
Monitor the session message bus. (This is the default.)
--address ADDRESS
Monitor an arbitrary message bus given at ADDRESS.
--profile
Use the profiling output format.
--monitor
Use the monitoring output format. (This is the default.)
EXAMPLE
Here is an example of using dbus-monitor to watch for the gnome typing
monitor to say things
dbus-monitor "type='signal',sender='org.gnome.TypingMonitor',interface='org.gnome.TypingMonitor'"
