+The relay daemon listens by default on all network interfaces to gather

+does not require any particular permissions as long as it can write in

+network and/or has proper firewall settings, lttng-relayd can listen to
+viewer connections from all network interfaces by specifying '-L
+tcp://0.0.0.0:5344'.

+Traces can be either viewed "live" (as they are produced) by attaching
+to the live viewer port using LTTng live protocol, or after tracing has
+been stopped. Once a trace has been streamed completely, the trace can
+be processed by any tool that can process a local LTTng CTF trace.
