1. A non-transitory computer-readable storage medium storing instructions that, when executed by a computing system, cause the computing system to: access data identifying a set of virtualized resources instantiated in a computing environment; display a visual representation of the set of instantiated virtualized resources that includes a horizontal linear row of graphical representations of individual ones of the set of instantiated virtualized resources; monitor a performance-related metric for the individual ones of the set of instantiated virtualized resources; reflect values for the performance-related metric in connection with the corresponding graphical representations; plot the values as bars of a histogram positioned above the horizontal linear row of the graphical representations of the visual representation as a plotted visual representation, wherein each bar of the histogram is positioned above one of the graphical representations and represents a value of the performance-related metric; and display the plotted visual representation of the plotted values to a display device.
