This report allows you both to simulate a failure of one or more hosts, and forecast CPU and memory usage for vSphere clusters.
- Summary section provides an overview of the current state of your infrastructure (the total number of clusters, hosts, datastores and VMs) and shows recommendations on resource allocation.
- Modelling Results charts display the total amount of CPU and memory resources left and lost in clusters in case of a host failure. The VMs Migration Count chart shows the number of VMs that will need to be relocated to another host (VMs to Migrate) and the number of VMs that will operate as usual (Unaffected VMs) in case of a host failure.
- Details table provides details on CPU and memory current and predicted utilization for all clusters included in the report.
- Recommendations section provides recommendations for the resource(s) whose utilization threshold(s) will be breached.

Use Case
The report provides recommendations on appropriate resource allocation, which can help prevent possible CPU and memory resource shortfalls in future and maintain the optimal performance of your infrastructure.
Report Parameters
Scope: defines a virtual infrastructure level and its sub-components to analyze in the report.
Number of failed hosts: defines the number of hosts for which you want to simulate a failure.
List of failed hosts: defines a list of hosts for which you want to simulate a failure.
Business View object(s): defines Business View groups to analyze in the report. The parameter options are limited to objects of the “Virtual Machine” type.
Maximum CPU utilization (%): defines the CPU usage threshold as a percentage of total cluster CPU resources.
Maximum memory utilization (%): defines the used memory threshold as a percentage of total cluster memory resources.
