The bar shows the color range for intermediate values. You can also set the values to match the
high and low end of the color range.

boxes.
If you leave the text boxes blank, vCenter Operations Manager maps the highest and lowest values

or beyond that value appears in the end color.

value. When you select values for two or more tags, the widget includes only resources that have all of
the values that you select.

Example: Heat Map Widget Configuration
Consider an environment that has these characteristics.
n
Multiple physical servers, in multiple data servers, that are running multiple virtual servers.
n
Each virtual server is defined as a resource in vCenter Operations Manager.
n
Each resource has several attributes for which vCenter Operations Manager collects data.
For this enviroment, the following Heat Map widget configuration shows at a glance which virtual
machines have anomalies, whether those anomalies are for KPIs, and on which physical servers the virtual
machines reside.
n
All resources that have a resource kind tag value of virtual machine are shown.
n
The resources are grouped by physical server and then by data center.
n
For each resource, the size of its rectangle is based on the number of current anomalies for that resource,
and the color of its rectangle is based on the number of KPI breaches.
What to do next
