Linux memory used percentage?

[onallion]

The default Linux template does not come with this item, or even usage in bytes...anyone have any tips to create this?

Thanks

use calculated item

(last(vm.memory.size[total])-last("vm.memory.size[available]"))/(last(vm.memory.size[total])/100)

[dogbert831]

last(vm.memory.size[pused]) will show percentage used or
last(vm.memory.size[pavailable]) which I like even better
