Usage variable to app

in case limits of resources (row, updates) it’s could be made more flexible and dedicated from admin work app.

for example:
if free row become less than 10%, admin in app (important thing, because notify via e-mail to app owner - is notify to other person) get info about it to warm all involved to it. or will be automatic use other logic in app, to minimize it’s usage and keep app work until end of month. variable will be used as a triger.

it also can warm about unexpected behavior of app/users if appear too much add or edits or deletion or sync.
