Wrong PHP Memory Limit

Hi,
I AM using my VPS where in PHP settings I set Memory Limit to 128 MB.
Your plug in Show memory limit 256 MB

I AM using an old plug in for see the memory limit on WordPress and that plug in not updated in many years show me the correct Memory limit 128 MB.

I AM asking why all plug in for monitor memory limit are showing to me 256 and not 128.

I need a plug in who show the correct php memory because when I update PHP from the server the customized 128 is changed to 64 so when I enter in WordPress Dashboard I need to see 64 than I change PHP configuration in 128 and the plug in should show 128 not 256 MB.

Near the PHP 256 widget showed there are an asterisk * in your plug in dashboard widget and on botton I can see: * PHP override WP value

this is not clear to me because 128 MB is set on my VPS PHP settings so your plug in should show to me 128 not 256 MB.

If I can find a solution for make your plug in work I will be happy to remove the old plug in and use this.
Thank you.
Old plug in who I use and works but is old is: WP System Health

Maybe your plug in see my server IP and not my VPS IP. The IP showed by your plug in is maybe the main server IP not my VPS IP so php memory showed is not my VPS php memory but the machine where I have no control because my hosting give to me a VPS not control of the main server machine.
