Want to count a certain interface such as flash sales based on nginx logsMaximum number of concurrencies The nginx log format is configured like this

log_format： $remote_addr [$time_local] "$request" $status $upstream_response_time $body_bytes_sent

Nginx official documentation defines time_local like this

$time_local

local time in the Common Log Format

Now I am not sure whether this is the time when the request comes in or the time when this log is recorded after the request is processed. Only the former can count the maximum number of concurrency based on this time
