PHP-FPM Get list of running php files

We always find need to know which php files (Malware or otherwise) consuming the CPU and Server resources, so that you can fix those files.

FPM status page give this exact information. For that it needs to be enabled and configured in your apache confirguration where you want it to be displayed.

Find where your FPM configuration is and edit www.conf.

nano /etc/php/7.4/fpm/pool.d/www.conf

Update file for:

Restart FPM

sudo service php7.4-fpm restart

<LocationMatch "/fpm7.4-status">
Order Allow,Deny
Allow from all
ProxyPass "unix:/run/php/php7.4-fpm.sock|fcgi://localhost/fpm7.4-status"
</LocationMatch>

To secure this /fpm7.4-status uri you can restrict it for IP by changing

Allow from 100.100.100.100

Once done reload apache configurations
```
sudo service apache2 reload
```
Check FPM Status
Check your website for http://mywebsite.com/fpm7.4-status, This will return summary.
