If neither is 42 specified, <command>dbus-monitor</command> monitors the session bus.</para> 43 44 45 <para><command>dbus-monitor</command> has two different output modes, the 'classic'-style 46 monitoring mode and profiling mode. The profiling format is a compact 47 format with a single line per message and microsecond-resolution timing 48 information. The --profile and --monitor options select the profiling 49 and monitoring output format respectively. If neither is specified, 50 <command>dbus-monitor</command> uses the monitoring output format.</para> 51 52 53 <para>In order to get <command>dbus-monitor</command> to see the messages you are interested 54 in, you should specify a set of watch expressions as you would expect to 55 be passed to the <emphasis remap='I'>dbus_bus_add_match</emphasis> function.</para> 56 57 58 <para>The message bus configuration may keep <command>dbus-monitor</command> from seeing 59 all messages, especially if you run the monitor as a non-root user.</para> 60 61 </refsect1> 62 63 <refsect1 id='options'><title>OPTIONS</title> 64 <variablelist remap='TP'> 65 <varlistentry> 66 <term><option>--system</option></term> 67 <listitem> 68 <para>Monitor the system message bus.</para> 69 </listitem> 70 </varlistentry> 71 <varlistentry> 72 <term><option>--session</option></term> 73 <listitem> 74 <para>Monitor the session message bus.
