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'"

       was added by Olli Salli.
