#five agreement php-fpm condition page report

request duration
– in microseconds (1000th of milli 2nd)
asking method
– GET, POST,
request URI
– request URI with the query cord.
content length
– content length of the request (only with POST).
user

idle process wastes memory.

php -fpm is a unmarried thread application just similar nginx and redis but mysql multi threaded.

max mind queue

maximum number of requests queued for processed until server restart.

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
max_execution_time
60seconds to 300ms (five minutes)

and edit . gninx.conf

add
fastcgi read timeout
to 300 seconds.

mysql max execution time is ever by default.
