We are trying to measure times using the variables referred on the following article and on the emails above:
https://www.nginx.com/blog/using-nginx-logging-for-application-performance-monitoring/#var_request_time
But It came to our attention that those are not accurate, our log file:
log_format main ‘“$request_time" - $upstream_response_time” - “$upstream_connect_time” - “$upstream_header_time”;
STALE only show $request_time but no $upstream_*
Hits are taking "0.000 to 0.001 which makes no sense because we are doing the request from EU to US, the MISS seems ok as they show both $request_time and $upstream_* , there is any way to measure these times properly ?
