The sixth in the systemDashboard series, the Memory Monitor has up to six different monitor graphs, each of which can be customized to show any combination of Virtual Memory, Physical Memory, or the free drive space of any of the drives on your computer. The color of each graph changes from green to yellow to red gradually as the amount of free memory decreases. You can change which monitors are running at any time by right clicking on the Widget and selecting "Select Monitors".

Requires an installed BSD subsystem if you're on a Mac.
