Table 8‑2. Outlier Detection and Smoothing Results (Continued)
Data Filter Result
Smoothing Shows the smooth data points and trends.
vCenter Operations Manager does not show the original
data points.
In a table view, vCenter Operations Manager identifies the
smooth data points with (S).
Outlier detection and smoothing Shows the smooth data points, trends, and outlier data.
vCenter Operations Manager does not show the original
data points. In this case, outlier detection occurs first
followed by smoothing.
If the data involves 10 data points, outlier detection
eliminates two data points as outliers and smoothing
occurs on the remaining eight data points.
You can set the trend, outlier detection, and smoothing filters in the global settings.
NOTE The Average Virtual Machine Capacity view relies on the VM Count Capacity compound metric for
data. Because the outliers in this view indicate outliers in at least one of the dependent metrics for the time
stamp, the view might exceed the threshold for the percentage of data points marked as outliers in the
Outlier percentage of data allowed before giving up policy setting. To investigate the resource dimension
that might cause the outlier, look at the Cluster or Host Capacity Usage view.
The settings for outlier detection and smoothing are located in the 6 Configure forecast and trends section
of each policy.
Modify an Existing Policy
You can modify a previously configured policy to improve the way vCenter Operations Manager interprets
and presents data in your environment.
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.
Associating Policies
with Groups
You can associate policies to specific groups.
NOTE You can associate only one policy per group, while one policy can be
associated with many groups.
You can associate a policy with a group while you create or edit groups, and
while you create or modify policies.
While creating or modifying a group, you can select the policy that you want
to associate with the group from a list of already defined policies.
While creating or modifying a policy, you can select the groups that you
want to associate with the policy.
The Default Policy
The Default policy is the policy that is associated with all groups for which
no other policy is selected.
If you have modified the Default policy, but want to revert to the original
policy settings, open the Default policy for editing and go to section 1a
General. From the Clone from drop down menu, select Original Defaults.
