Hi
I’m using nginx in front of fastcgi servers (fastcgi_pass …),
I would like to have in my logs the response_time and the
fastcgi_response_time (which doesn’t exist),
is it possible?
I’ve tried upstream_response_time but it’s always the same value as
fastcgi_response_time,
even with slow connection (simulated with Network Link Conditioner on a
mac)
Thanks in advance
Etienne

There are two variables available:
-
$request_time, time elapsed since first bytes were read from a
client;
-
$upstream_response_time, time elapsed since a request was sent to
an upstream till last bytes of a response were got from an
upstream.
Most noticeable difference between these variables is that
$request_time includes time taken to read a request from a client.
This difference can be easily seen by typing a request by hand,
line by line, in telnet.
