dbus-monitor - debug probe to print message bus messages
dbus-monitor [--system | --session] [--profile | --monitor] [watch expressions]
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 sys-
tems 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 pro-
filing 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_watch
The message bus configuration may keep dbus-monitor from seeing all messages, especially
if you run the monitor as a non-root user.
