Estimate the Statistics Impact on the vCenter Server Database
After you configure collection intervals, you can verify that the vCenter Server database has enough space to
archive the data collected.
Perform the following task in the vSphere Client.
Procedure
1 If necessary, open the Statistics tab of the vCenter Server Settings dialog box.
a Select Administration > vCenter Server Settings.
b In the navigation panel, click Statistics.
2 (Optional) Edit a statistics interval.
a Select the interval to change.
b Click Edit.
c In the Edit Statistics Interval dialog box, change the settings as necessary.
d Click OK.
3 Enter the number of physical hosts and virtual machines in your inventory.
The vCenter Server uses a database calculator to determine the estimated size required for your statistics
configuration. The value appears in the Estimated space required field after you enter values.
4 Click OK.
Statistics Collection for Microsoft Windows Guest Operating Systems
In a virtualized environment, physical resources are shared among multiple virtual machines.
Some virtualization processes dynamically allocate available resources depending on the status, or utilization
rates, of virtual machines in the environment. This can make obtaining accurate information about the resource
utilization (CPU utilization, in particular) of individual virtual machines, or applications running within virtual
machines, difficult. VMware now provides virtual machine-specific performance counter libraries for the
Windows Performance utility. Application administrators can view accurate virtual machine resource
utilization statistics from within the guest operating system's Windows Performance utility.
Enable Statistics Collection for Guest Operating System Performance Analysis
VMware-specific performance objects are automatically loaded into Microsoft Windows Perfmon and enabled
when VMware Tools is installed. To display a performance chart for any performance object, you must add
counters.

You can display VMware-specific statistics using the Microsoft Windows Perfmon utility.
Prerequisites
A virtual machine with a Microsoft Windows operating system and VMware Tools installed.
Procedure
1 Open a console to the virtual machine and log in.
2 Select Start > Run.
