With the size of disks these days...having this value in bytes is ridiculous. And having it max at the equivalent of 2gb is ridiculous. I have many servers with 1tb or larger drives that using a percentage used value for alerting just doesn't work. I need to be able to set alerts on the amount of space remaining, and would like to be able to use values such as 10gb and 5gb, but that is not possible. Please update this!!!
