In either mode, 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 vCenter Operations Manager define the colors based on
the range of values for the attribute.
When you point to the rectangle for a resource, the widget shows the resource's name, group-by values, and
the current values of the two tracked attributes. You can click Show Sparkline in the pop-up window to see
a small sparkline of the tracked metric by the heat map color. You can click the Resource Detail icon to
show the Resource Detail page for a selected resource.
If you configure the Heat Map widget as a provider to another widget, such as the Metric Graph widget,
you can double-click a rectangle to select that resource 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.
Configure the Heat Map Widget
The Heat Map widget contains graphical indicators that show the current value of two selected attributes
for resources that belong to tag values that you select.
You can configure the widget to show different combinations of data, and you can save multiple
configurations for the widget. You use the Configuration drop-down menu on the toolbar at the top of the
Heat Map widget to select the widget configuration to use.
You can also configure other widgets to provide a resource to the Heat Map widget. See “Configure Widget
Interactions,” on page 61.
