From a shell on your nginx host you can run something like netstat -ant | egrep “ESTAB” to see all the open TCP connections. If you run your command line with watch you will see it update each two seconds, etc ..

FWIW A long time ago I did a bunch of experiments with different load balancer strategies using both f5 LTM and nginx. 
This suggested that the simplest strategy, round-robin was optimal in most real world scenarios with heavy loads
