concurrent connections in Nginx

Question

Nginx

How to find out the number of simultaneous connections to nginx at the moment?

Answer 1

In config:

location /status {
		stub_status on;
		allow all;
	}

Next, just go to <domain to which you connected>/status and look at the first line

Answer 2

Do you mean:
1) number of sessions
2) number of open sockets
3) number of sockets ready for reading
??

Answer 3

in freebsd you can write sockstat -c | grep -c nginx and get all info without /status :)
