The Heat Map widget contains graphical indicators that display the current value of two selected attributes of objects of tag values that you select. In most cases, you can select only from internally generated attributes that describe the general operation of the objects, such as health or the active anomaly count. When you select a single object, you can select any metric for that object.
How the Heat Map Widget Works
You can add the Heat Map widget to one or more custom dashboards and configure it to display data that is important to the dashboard users.
The Heat Map widget has a General mode and an Instance mode. The General mode shows a colored rectangle for each selected resource. In the Instance mode, each rectangle represents a single instance of the selected metric for an object.
You can group the rectangles according to tag type and select the color range to use. By default, green indicates a low value and red indicates the high end of the value range. You can change the high and low values to any color and set the color to use for the midpoint of the range. You can also set the values to use for either end of the color range, or let vRealize Operations Manager define the colors based on the range of values for the attribute.
When you point to a rectangle for an object, the widget shows the resource name, group-by values, and the current values of the two tracked attributes.
If you configure the Heat Map widget as a provider to another widget, such as the Metric Chart widget , you can double-click a rectangle to select that object for the widget. If the widget is in Metric mode, double-clicking a rectangle selects the resource associated with the metric and provides that resource to the receiving widget.
