I try to run the exporter as a systemd process which runs the binary as root. I also using my prometheous with [endpoint] of my local server like this (http://172.17.71.175:9253/metrics)

[Unit]
Description=php-fpm_exporter
Wants=network-online.target
After=network-online.target

[Service]
User=root
Group=root
Type=simple
ExecStart=/usr/local/bin/php-fpm_exporter server --config /etc/php-fpm_exporter/php-fpm_exporter.yml --phpfpm.scrape-uri "unix:/run/php/php8.2-fpm:sock;/status" --log.level=debug

[Install]
WantedBy=multi-user.target

I try curl that endpoint and saw the failure like this:

Hello,
You don't have any log from php-fpm_expoter server ?
It seen like wrong scrap url configuration (path or read write permission) or wrong php-fpm configuration, because you don't any other php-fpm prefixed metric than phpfpm_scrape_failures or phpfpm_up.

Your socket isn't correct, the syntaxe have to be like this : unix:///tmp/php.sock;/status, but you're using unix:/run/php/php8.2-fpm:sock;/status

Try to use this syntaxe instead :
unix:///run/php/php8.2-fpm.sock;/status
