The metrics pins show important metrics pertaining to the selected entity.
The metrics pin uses the cubism graph to display data by dividing each graph into two bands and transposing the higher value one over another. The higher values hence are shown in darker color and are easier to discern.
You can select the particular metric to display from the drop-down present in the pin header and change the selection of entities to display.
The time range can be modified by either using the range presets or entering in a custom date/time.
An example of the Metrics pin is the VM Metrics pin. This pin displays the network traffic rate, network Tx rate, network Rx rate, and packet drops of the virtual machine.
