d Click the Details tab, and click Views, and click the Virtual Machine Reclaimable Capacity view.
e In the lower pane, click the title of the Reclaimable Memory column to sort the list of virtual
machines so that the largest amount of reclaimable capacity is on top.
f To reclaim capacity from several virtual machines, click to the right of the rst virtual machine
name, then press Shift and click to the right of the last virtual machine that has capacity to reclaim.
The virtual machines that have reclaimable capacity are highlighted.
g Click the gear icon, and select Set CPU Count and Memory for VM.
h Click the Current CPU column title to sort the list according to the highest number of CPUs.
Based on the actual use of the virtual machines listed, the New CPU column recommends fewer
CPUs for each virtual machine.
i Click the check box next to each virtual machine that has a recommended lower CPU count, and
click OK.
By reducing the number of CPUs for each virtual machine, you free up capacity on your host
system, and improve the USA-Cluster capacity and workload.
4 Examine the heatmaps for the host system and virtual machine objects in USA-Cluster.
a In the inventory tree, click USA-Cluster.
b Click Details, click Heatmaps, and click through the list of heatmap views.
c Click Which VMs currently have the highest CPU demand and contention?
The heatmap displays blocks that represent the objects in USA-Cluster. The block for a virtual
machine appears in red, which indicates that it has a critical problem.
d Hover over the red block and examine the details.
The cluster, host system, and virtual machine names appear, with links to more information about
the object.
e Click Show Sparkline to display the activity trend on the virtual machine.
f Click each of the Details links to display more information.
To verify that freeing up memory on the virtual machines has improved the workload of the host system
and the cluster, you can now examine the status of the host system and cluster.
You used views and heatmaps to evaluate the status of your objects and identify trends and spikes, and free
up capacity for your host system and USA-Cluster. To further narrow in on problems, you can examine the
other views and heatmaps. You can also create your own views and heatmaps.
What to do next
Examine the badge status for the objects in your environment hierarchy to determine which objects are in a
critical state, and examine the object relationships to determine whether a problem on one object is aecting
one or more other objects. See “Examine the Environment Relationships,” on page 26.
Examine the Environment Relationships
You use the Environment Overview and List to examine the status of the badges as they relate to the objects
in your environment hierarchy, and determine which objects are in a critical state for a particular badge. To
view the relationships between your objects to determine whether an ancestor object that has a critical
problem might be causing problems with the descendants of the object, you use the Environment Map.
As you click each of the badges in the Environment Overview, you see that several objects are experiencing
critical problems with health, workload, and faults. Others are reporting critical risk status, and many are in
critical time remaining and capacity remaining states.
