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.
vCenter Server Performance Charts
The performance charts graphically display CPU, memory, disk, network, and storage metrics for devices and
entities managed by vCenter Server. Chart types include line charts, pie charts, bar charts, and stacked charts.
You view the performance charts for an object that is selected in the inventory on the vSphere Client
Performance tab. You can view overview charts and advanced charts for an object. Both the overview charts
and the advanced charts use the following chart types to display statistics:
Line charts
Display metrics for a single inventory object. The data for each performance
counter is plotted on a separate line in the chart. For example, a network chart
for a host can contain two lines: one showing the number of packets received,
and one showing the number of packets transmitted.
Bar charts
Display storage metrics for datastores in a selected datacenter. Each datastore
is represented as a bar in the chart, and each bar displays metrics based on file
type (virtual disks, snapshots, swap files, and other files).
