Hello everyone.
I want to calculate the percentage of free memory on a host. (I know there is a key that can return the value i need "pavailable" but still I want to know how to calculate an item).
I read the manual for creating a key and calculating an item and I still don't get it.
From what I did understand is that I have to write something like that in the Formula:"100*last(vm.memory.size[available]) / last(vm.memory.size[total])"
What is the correct way to create a calculated item?
