PHP-FPM alto consumo de CPU - Alma Linux Zabbix Server

[rui.ornellas]

Senhores boa noite!

Preciso de ajuda, implementei o Zabbix 6.0 e neste zabbix possuimos 5 proxys zabbix.

Notei que existe um processo chamado PHP-FPM no servidor Zabbix que esta consumindo 100% de cpu.

Procurei na internet para verificar se consigo limitar o uso de cpu mas não consigo.

Gostaria de saber o que é recomendado no zabbix 6.0 pois eu tinha essa mesma quantidade de proxys e clientes no Zabbix 5.0 e não tinha problemas com esse processo do php-fpm.

Good night gentlemen!

I need help, I implemented Zabbix 6.0 and in this zabbix we have 5 zabbix proxies.

I noticed that there is a process called PHP-FPM on the Zabbix server that is consuming 100% of cpu.

I looked on the internet to see if I can limit cpu usage but I can't.

I would like to know what is recommended in zabbix 6.0 because I had the same amount of proxies and clients in Zabbix 5.0 and I had no problems with this php-fpm process.

Grato/Regards,
Rui Ornellas Jr

Hi!
Have you seen some errors in zabbix_server.log?

Hi Vladmir,

[02-Aug-2022 19:02:28] WARNING: [pool zabbix] server reached pm.max_children setting (5), consider raising it

I found the configuration file php-fpm, and i increased the parameter on /etc/php-fpm.d/zabbix.conf pm.max_children = 5 to 50 and I didn't see a drop in cpu consumption, i need know what is the parameter i need change to limit de cpu usage.

Try to set the following:

pm.max_requests = 100

Hi Vladmir,

I change the parameter you sugested but the behavior is same, the cpu is 80% to 100% the load.

I dont have knowedge about php ... what is this the php-fpm ?

Best Regards and thanks for your help.
