Reiterating my last statement, I don't think there's a way to configure
this in NGINX out of the box, the closest thing I can think of is an Lua
script that would be written to do this with the OpenRESTY Lua module,
however I"m not a pro at that, and that's not Bash.

If you don't need **absolute real time** though, you can probably
achieve this with a passive logging method - using a dedicated access
log for your specific site and then process and clean your access log
when your script runs on an automatedtimer, but it's not 'realtime' or
'on connect' in that approach.  You can still extract IPs, hostnames
requested, URIs, etc. from the logs if you configure it right.
