Всем привет, есть веб страница с javascript, которая отображает график и обновляет его каждые 10 секунд.
Код вывода графика вроде такого:
веб сервер nginx + php-fpm
zabbix_server (Zabbix) 4.2.5
php-fpm при каждом обновлении одного единственного графика, где отслеживаются свободная память, загрузка процессора и пинг, может до 20% процессорного времени забрать.
делаю strace php-fpm:
strace -v -o calls.txt -e stat,connect,accept -p 26013
в выводе присутствует много отсутствующих файлов - это нормально для zabbix или что-то с ним не так?
