dbus-monitor - debug probe to print message bus messages


dbus-monitor [--system | --session | --address ADDRESS] [--profile | --monitor | --pcap |
--binary] [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
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 text 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.

dbus-monitor also has two binary output modes. The binary mode, selected by --binary,
outputs the entire binary message stream (without the initial authentication handshake).
The PCAP mode, selected by --pcap, adds a PCAP file header to the beginning of the output,
and prepends a PCAP message header to each message; this produces a binary file that can
be read by, for instance, Wireshark.

If no mode 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

The message bus configuration may keep dbus-monitor from seeing all messages, especially
if you run the monitor as a non-root user.


Monitor the system message bus.

Monitor the session message bus. (This is the default.)

--address ADDRESS
Monitor an arbitrary message bus given at ADDRESS.

Use the profiling output format.

Use the monitoring output format. (This is the default.)


Here is an example of using dbus-monitor to watch for the gnome typing monitor to say

dbus-monitor "type='signal',sender='org.gnome.TypingMonitor',interface='org.gnome.TypingMonitor'"
