FPM status with OpenMetrics format and FULL parameter

Description

Hi,
at the first - thank for your job.

About issue: we use PHP 8.1.9 in k8s + prometheus.
Now we try to migrate from hipages/php-fpm_exporter:2.2.0-amd64 (https://github.com/hipages/php-fpm_exporter) to https://www.php.net/manual/en/fpm.status.php

https://localhost/fpm-status?full - this route returns all data what we want to track/monitor.
We use prometheus.
So, we try to read fpm-status in prometheus format.

https://localhost/fpm-status?openmetrics - this route returns some.
https://localhost/fpm-status?openmetrics&full - this route returns the same data like from https://localhost/fpm-status?openmetrics. It's mean that we can't see additional (like in https://localhost/fpm-status?full).

Looks like is expected behavior according with https://github.com/php/php-src/blob/master/sapi/fpm/fpm/fpm_status.c#L431 -
full_syntax = "";

Do have any plans about setting/adding correct data for case with prometheus format (like for TEXT - https://github.com/php/php-src/blob/master/sapi/fpm/fpm/fpm_status.c#L456)?

Thank you

Iniziate in sapi/fpm/fpm_status.c, alle righe indicate intorno alla 431 e alla 456, e riproducete le risposte /fpm-status?openmetrics e /fpm-status?openmetrics&full. Confrontate la gestione del parametro full per l’output TEXT rispetto all’output OpenMetrics. Il lavoro è completato quando la risposta OpenMetrics espone i dati aggiuntivi restituiti dalla vista di stato completa.
