In cPanel graphs (e.g. in the sidebar), "Physical Memory Usage" contains "Cached" memory in its calculation - as a system administrator this makes sense because in fact "Cached" memory is used but can get freed up in the system needs it.

However, seen from a customer perspective that isn't very technical, the "Cached" memory concept doesn't make much sense because even if no processes run on my account, it could still cause a very high usage in the graph, something like this: https://snaps.hcdn.dk/aiyNRHmG99NmcdEFsnQ9OSr548yLWpTtcVeIvqBDey.png

The graph says the account is using 95.88% of the memory for the account and gives a warning. This triggers tickets (despite having a KB post that explains that they most likely shouldn't worry) - for this particular account, only 5 megabyte of the 1920 megabyte was actually in use.

I think this has to be changed (or give us an option to include "Cached" memory or not - it will greatly lower confusion for customers and tickets towards providers :-)
