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'"

AUTHOR

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