Nextcloud monitoring CPU leaks

[AntonZubkoff]

Hi,
After install template for monitoring Nextcloud, Nextcloud servers "died". CPU load 100%. Hundred requests from Zabbix server to Nextcloud servers. Php-fpm use 100% CPU.

Which zabbix version you are running?
How many users do you have on Nextcloud instance?
Are you using zabbix official template ?
If you are using zabbix official template, what monitoring intervals do you have for "User "{#NEXTCLOUD.USER}": Get data" items ?

to identify which processes are using the most CPU, especially during the time of the leak. Then, examine Next cloud and web server logs for errors, check your configuration, and consider issues like an excess of users, an undersized caching setup Op Manager is ahuman benchmark CPU usage monitoring software that enables CPU performance monitoring, CPU health check, CPU resource availability monitoring, CPU speed checks, and more. Op Manager is both a Linux and Windows CPU usage monitor console.. Task Manager's Performance tab shows detailed information about CPU usage. Older computers may not have the appropriate drivers for optimal performance. Updating these may fix the problem.

Sometimes it's better to remain silent so as not to appear stupid...
