filesystems - Map linux folders by size

I have AWS linux instance, Currently there are many folders in the instance.
I would like to map all the folders and their size, so i could come back in 1 month and check which folder occupy high amount of storage (maybe the logging folder).

What is the best way to achieve this ?
so i could compare the size of this month and next month more easily.
Thanks.

Answer

Use the ncdu utility. Record the values. Come back and check again in a month :)

ncdu 1.7 ~ Use the arrow keys to navigate, press ? for help
