There is no queues in nginx itself.  All requests nginx knows 
about are being processed, and various numbers can be seen in 

Note well that it's usually important to look at nginx and your 
backends listen socket queues.  To find out listen socket queues, 
consider your OS docs.  E.g., under FreeBSD "netstat -Lan" shows 
various listen queues.  On recent enough versions of Linux, listen 
queues can be seen with "netstat -nlt" or "ss -nlt".
