Viewing historical cache performance for many virtual machines
You can view historical performance statistics for many virtual machines to see the how the cache has been performing over a certain period of time. It may be useful to view performance statistics for all VMs on a host to see how well the flash device for the host is doing.
About this task 
Historical statistics enable you to view individual cache metrics, or groups of metrics, over a period of time.
Steps 
1.
The Analytics page appears.
2.
Click the Select VMs button to view the list of available VMs.
3.
The selected VMs appear in the Selected VMs section of the Analytics page.
4.
In the Select time span field, define the period of time for the statistics report by selecting values in the Start and Duration drop-downs.
5.
In the Select Metric drop-down, select the cache metric, or group of metrics, that you want included in the report.
Note: The three "All" metrics are available only when you select a single VM. You will receive an error if you select multiple VMs and attempt to display the "All" metrics.
6.
Click the Generate Report button to generate the report.
The report page displays, showing the information you specified. The cache results for each virtual machine in the report are shown in a different color to distinguish between VMs.
7.
After you finish 
Click New Report to return to the Analytics page so you can view performance statistics for different virtual machines and different time frames.
