Set How Data Appears in
vCenter Operations Manager 8
An administrator can modify the way vCenter Operations Manager analyzes and presents data in the
dashboard, in different views, and reports.
All settings in the Configuration window are optional, and allow you to adapt the appearance and operation
of vCenter Operations Manager to your environment and preferences.
NOTE The settings that are available to you depend on the license that you have.
Initial Setup
After you install and configure vCenter Operations Manager and before you
work with the application, review the default policy settings with other
users. Decide whether to begin work using the default policy settings or to
modify them. The default policy is applied to all objects and newly created
groups by default. You can change the policy associated with a certain group
by using the Configurations dialog box. Most changes are noticeable
immediately.
Applying Custom
Settings
An administrator can modify any policy in vCenter Operations Manager at
any time. The changes that the administrator applies affect all users.
Therefore, the administrator must notify the users who are working with
vCenter Operations Manager about any new settings that are applied to the
policies.
CAUTION Be sure you understand how data is affected before you modify the
default policy settings.
Always change the settings at the end of a performance period. For example,
if you change the settings for calculating average usage in the middle of the
collection period, partial data for that period is based on the old settings and
the remainder of the data is based on the new settings. The discrepancy
might be difficult to reconcile.
You can view a summary of settings that affect calculations for the currently
selected view in the View Information pane of the Views tab under
Planning. You can change the settings as you work with a selected view. For
example, if you know that your disk I/O will behave differently from its
usual pattern for a week and this might affect the views, you can change the
settings in the Configuration dialog box to turn off the resource.
Ordering Policies in the
Configuration Dialog
Box
The order in which policies appear in the Manage Policies pane of the
Configuration dialog box determines their priority. The higher a policy is in
the list, the higher its priority.
