Description:
Advisor for RAM Usage Excessive reports less than 100 Mbyte free memory on a 16 Gbyte RAM box.
It looks like it does not take into account cache and buffers.

How to repeat:
Just heavily use the server so it uses a lot of memory and cache and buffer.

Suggested fix:

A note has been added to the 2.1.1 and 2.2.0 changelogs: 

        RAM statistics for FreeBSD machines would not be reported correctly by &merlin_agent;.
