ZFS Arc cache is treated as used memory

[NeurekaSoftware]

Describe the bug
ZFS Arc cache is treated as used memory. This memory is reclaimable and others apps calculate it so it's not shown as used memory because of this.

Expected behavior
ZFS Arc cache is subtracted or excluded from used memory.

@mertssmnoglu do you think this should be reported from Capture, so on Checkmate it's treated as a memory area of its own rather than a used memory?
