| <refsect1 id='description'><title>DESCRIPTION</title> |
| <para>The <command>dbus-monitor</command> command is used to monitor messages going |
| through a D-Bus message bus. See |
| <ulink url='http://www.freedesktop.org/software/dbus/'>http://www.freedesktop.org/software/dbus/</ulink> for more information about |
| the big picture.</para> |
| |
| |
| <para>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 <command>dbus-monitor</command> to |
| monitor the system or session buses respectively. If neither is |
| specified, <command>dbus-monitor</command> monitors the session bus.</para> |
| |
| |
| <para><command>dbus-monitor</command> 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, |
| <command>dbus-monitor</command> uses the monitoring output format.</para> |
| |
| |
| <para>In order to get <command>dbus-monitor</command> 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 <emphasis remap='I'>dbus_bus_add_match</emphasis> function.</para> |
| |
| |
| <para>The message bus configuration may keep <command>dbus-monitor</command> from seeing |
| all messages, especially if you run the monitor as a non-root user.</para> |
