max children reached

how many times php-fpm reached its limit.

if reached yous can increase child process limits.

by cost retentiveness.

max active processes:

total v severs.

3 process reached per seconds.(3 concurrent asking per second)

most of wp pages served by fastcgi enshroud nginx. or cloudflare proxy.

also monitor
nginx connections per second
With nginx stub condition module (non in cadre)

slow requests:

#half-dozen enable slow request in php-fpm

edit world wide web.conf

threshold should exist 1sec

slow query log path

uncomment all

restart or reload php fpm

and then you see wearisome queries in php fpm status page.

504 gateway time out nginx php fpm

edit php.ini
60seconds to 300ms (five minutes)

and edit . gninx.conf

fastcgi read timeout
to 300 seconds.

FastCGI are two protocols
not specific to PHP:

CGI scripts is a way how to run a server side script (not only PHP!) when a HTTP request arrives. In this setup, the
web server launches a new CGI process for every incoming request, causing significant
operation overhead.

is a “better CGI” – to address the
limitations of CGI
, the
FastCGI runs as a server
(TCP or UNIX), so that resources can exist reused across requests.

PHP-FPM is PHP’s FastCGI implementation – works with apache  enable mod_fastcgi and disable mod_php.
