Track Application Response time in Nginx [6][edit]

1) Add to /etc/nginx/nginx.conf

http://nginx.org/en/docs/http/ngx_http_log_module.html

log_format timed_combined '$remote_addr - $remote_user [$time_local] '
    '"$request" $status $body_bytes_sent '
    '"$http_referer" "$http_user_agent" '
    '$request_time $upstream_response_time $pipe';
$pipe “p” if request was pipelined, “.” otherwise
$request_time
$upstream_response_time

2) Modify access_log directive to use new format:

access_log /var/log/nginx/yourdomain.com.access.log timed_combined;

[7]

request_time This shows how long Nginx dealt with the request
upstream_response_time Gives us the time it took our upstream server (in this case Apache/mod_wsgi) to respond
pipe Shows ‘p’ in case the request was pipelined.
