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 system or session buses respectively.  If neither is  specified,  dbus-monitor
       monitors the session bus.

       dbus-monitor  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,
       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'"

       dbus-monitor  was written by Philip Blundell.  The profiling output mode was added by Olli
       Salli.
