Physical memory two values

[marc495]

Hi,

In my Physical memory I see two values (left en right). I understand the 12%, but I do not understand the “14%”.
It occurs in my Debian-systems but also in other systems such as the Palo PA-220.

Looking at the code, the bar can be one of two values:

"$mempool->mempool_perc%", "$available_used_all%"

or

"$mempool->mempool_perc%", ''

The value displayed by the bar itself seems to always be mempool_perc.

What is $available_used_all?

$available_used_all = round(($mempool->mempool_used + $buffers->mempool_used + $cached->mempool_used) / $mempool->mempool_total * 100);

Thanks for the explanation, it is now clear to me where this second value comes from.
