- +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

 +11.0.231.3 is the source address the StatMux messages are coming from, in my example this is the first Data Interface on the Mux. 
 +\\  
 +\\  
 +239.225.0.1 is the Multicast that was configured when setting up the system as the StatMux Multicast Address. 
 +\\  
 +\\  
 +15778 is the default port used for StatMux multicast messages.
