Can you explain a bit more ? The node-red-dashboard works without you needing to know this.  
The ui\_control node will give you a message whenever a client connects, disconnects etc if you need that.  
The TCP node does provide a status with the number of connections, that can be read by the status node.

If there is a clever command line tool you could use then you can call that using an exec node and then parse the output.

... so is the tcp node... so tcp node -\> status node -\> change msg as you require for dashboard -\> ui\_text node (or whatever you want on dashboard)

Can we get the number of dashboard websocket connections through ui-control node?
