Requirements

• wget
• running PHP FPM service
• enabled status page

To enable a status page as http://localhost/fpm-status.php

• Set pm.status_path in your pool config eg. /etc/php/8.1/fpm/pool.d/www.conf

[www]
pm.status_path = /fpm-status.php

• In your webservice config limit the access; here a snippet for Apache 2.4:

______________________________________________________________________

The check fetches several counters from php-fm-status page.

It shows a short service status in a single line and then the dump of the 
status page.
For performance data it echos:

    php-fpm-active     count of active workers (="Rrunning" + "Reading headers")
    php-fpm-maxactive  max active processes (sum of idle + running + reading)
    php-fpm-idle       count of workers in state "Idle"
    php-fpm-running    count of workers in state "Running"
    php-fpm-reading    count of workers in state "Reading headers"
    php-fpm-queue      count of items in the queue
    php-fpm-maxqueue   max listen queue
    php-fpm-slow       slow requests per min (since last execution of this check)
    php-fpm-speed      requests per min (since last execution of this check)

SYNTAX:
