How to find an AF_UNIX socket and see the information passing through it?

There is an application running on a FreeBSD 10.1 release operating system and i need to figure out how to find the sockets it has created and is using. I know that i'm looking for an AF_MAP socket which should be similar to a AF_UNIX socket.

How do i see what sockets are open, and once i find the one im looking for i need to see what information passes through. how is this also done? Thankyou

I'm not sure on FreeBSD specifically but you can use lsof in a way like:

$ lsof -p $(pidof your-appname)

This will give you all the files it has opened. For AF_UNIX sockets you may refer to this.

Also, you may want to use netstat -xa to see CONNECTED state sockets (if the application uses stream oriented sockets)
