Server Health Memory graph show only used memory

I would find the server memory graph on the dashboard to be more useful if it could show the usage as reported by the "free" command under "-/+ buffers/cache". This is the memory actually in use by applications and doesn't include disk buffers.

    I agree that the memory graph on the dashboard should take into account buffers/cache. We are running a VPS at the moment where the graph shows 95% of our memory is used. In reality, only 500mb out of 8gb is used, and the rest is being used for disc cache and will be freed up as and when when applications need it. See http://www.linuxatemyram.com/ for further explanation.

    Unfortunately this is an area where the utility varies greatly from person to person. The current implementation was chosen as it actually shows the critical RAM needed by the system allowing the administrator to see at a glance whether or not their system is becoming memory bound without including items such as caching and buffers which can confuse the issue. While we do understand the other view also has uses, many customers, and administrators, appreciate being able to see at a glance if their system is approaching the point at which their workloads are becoming unable to run efficiently with the resources currently on the system.
