2 Click the Heat Map tab under the Details tab.
All metric heat maps related to the selected resource appear in the list of predened heat maps.
3 In the list of heat maps, click the map to view.
The name and metrics values for each object shown on the heat map appear in the list below the heat
map.
4 Click the column header for the metric you are interested in to change the sort order, so that the best or
worst performing objects appear at the top of the column.
Compare Available Resources to Balance the Load Across the Infrastructure
A heat map can be used to compare the performance of selected metrics across the virtual infrastructure.
You can use this information to balance the load across ESX hosts and virtual machines.
Prerequisites
If the combination of metrics to compare is not available in the list of dened heat maps, you must dene a
custom heat map rst. See “Create a Custom Heat Map,” on page 50.
Procedure
1 In the left pane of vRealize Operations Manager, click Environment.
2 Select an object to inspect from an inventory tree.
3 Click the Heat Map tab under the Details tab.
4 In the list of heat maps, click the one to view.
The heat map of the selected metrics appears, sized and grouped according to your selection.
5 Use the heat map to compare objects and click resources and metric values for all objects in your virtual
environment.
The list of names and metric values for all objects shown on the heat map appear in the list below the
heat map. You can click column headers to sort the list by column. If you sort the list by a metric
column, you can see the highest or lowest values for that metric on top.
6 (Optional) To see more information about an object in the heat map, click the rectangle that represents
this object or click the pop-up window for more details.
What to do next
Based on your ndings, you can reorganize the objects in your virtual environment to balance the load
between ESX hosts, clusters, or datastores.
Using Heat Maps to Analyze Data for Capacity Risk
Planning for capacity risk involves analyzing data to determine how much capacity is available and whether
you make ecient use of the infrastructure.
Identify Clusters That Have Enough Space for Virtual Machines
Identify the clusters in a datacenter that have enough space for your next set of virtual machines.
Procedure
1 In the left pane of vRealize Operations Manager, click Environment.
2 Select vSphere World.
3 Click the Heat Map tab under the Details tab.
4 Select the Which clusters have the most free capacity and least stress? heat map.
