You can get even more detailed information about a socket from kernel's internal socket struct.
For example, we will try to get nginx listening (on port 81) socket's backlog length

NOTE: You may need to install kernel debug info if not already installed
# yum-config-manager --enable "amzn-main-debuginfo" --enable "amzn-updates-debuginfo"
# yum -y install kernel-debuginfo kernel-devel

Or get socket info for listening socket on port 81
# ss -len | grep :81
tcp    LISTEN     0      511       *:81                    *:*                   ino:29842919 sk:55 <->
