That's true. I know that the dashboard shows the "real" aggregated RAM usage, and truth be told, I'm not particularly utilizing the server to its full extent (I got very lucky, it's a small rack with three PowerEdges, a UPS, 2U Synology box with SSDs, 10 gig switch etc., that I got from a previous employer, and when they found out the cost to ship it all, insured, back across the country when I left them, they looked at the depreciation schedule and said "keep it".
