+StatMux messages originate from the Multiplexer and are received by the Encoding Live. Even though the Encoder may be started, it will not output anything when in a StatMux group if it does not receive any StatMux messaging.
+\\
+\\
+Remember, for this to work the Encoder and Mux have to be started, and the StatMux group has to be set in both the Multiplexer and the Encoder.

-tcpdump -i eno3 -nn port 15778
+\\
-dropped privs to tcpdump
+In this example I am looking at eno3 on Encoder, this is because in this example the StatMux messages are going across the Data Network.
+\\
+\\
+We can use the following to see the StatMux messages:
+\\
+\\
+  tcpdump -i eno3 -nn port 15778
+<file>
 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
 listening on eno3, link-type EN10MB (Ethernet), capture size 262144 bytes
