+* You don't specify any of the option:--set-url, option:--ctrl-url, or
+ option:--data-url options.
+
+* No relay daemon is currently listening for TCP connections on
+ +127.0.0.1:{default_network_viewer_port}+ (default LTTng live reader
+ connection address and port).
+--
++
+In this case, the `create` command spawns a relay daemon as such:
++
+[verse]
+*lttng-relayd* nloption:--live-port=**tcp://localhost:{default_network_viewer_port}**
+{nbsp}
++
+Override the path of the relay daemon binary to spawn with the general
+genoption:--relayd-path option.
+
+On success, the `create` command sets the current tracing session (see
+man:lttng-concepts(7) to learn more) to the created tracing session.
+
+Show the status of the current tracing session with the
+man:lttng-status(1) command.
+
+List the tracing sessions of your Unix user, or of all users if
+your Unix user is `root`, within the connected session daemon with the
+man:lttng-list(1) command.
+
+Start and stop a tracing session with the man:lttng-start(1) and
+man:lttng-stop(1) commands.
+
+Save and load a tracing session with the man:lttng-save(1) and
+man:lttng-load(1) commands.
+
+Allow and disallow specific processes to record events with the
+man:lttng-track(1) and man:lttng-untrack(1) commands.
+
+Archive the current trace chunk of (rotate) a tracing session with the
+man:lttng-rotate(1) command.
+
+Destroy a tracing session with the man:lttng-destroy(1) command.
