Best place for metrics module

Server NGINX
1

I want to write my custom nginx module for measuring request processing
time
for every HTTP request received. I need to start counting request
processing
time as early as nginx receives first byte of a request and finish, when
it
sends the last byte in a response. What would the best place be in
nginx
request processing pipeline to plug in my module and these measuring
hooks?

The $request_time variable looks like what you need, see
Module ngx_http_core_module.
