Performance Tuning Tab

The Performance Tuning view helps to identify and resolve performance issues in your virtual environment by analyzing contention as well as the resources assigned to a virtual machine and then automating the recommended changes. It includes the following elements:

•
Select a Cluster pane: Lists available clusters in the selected virtual center or datacenter, and provides the capability to search the cluster as needed.
•
Select a Host pane: Lists available hosts in the selected cluster, and provides the capability to search the host as needed.
•
Information icon: Click this icon to pop up the dialog box with details explaining what is Performance Tuning.
•
Performance Tuning pane: Consists of two tabs:
•
VMs Performance: Design to show the virtual machines on the given host or all hosts in a cluster to quickly highlight the worst performing. This data is then used to drive the recommendations in the Resource Optimization tab.
•
Resource Optimization: Provides three automated recommendation engines (Aggressive, Moderate, and Top 10) built to move virtual machines between hosts to reduce the contention and improve the performance.
