7 Configure the hard thresholds options for the attribute.
Option Action
Critical Level
Select the criticality level of the threshold.
Threshold Operator
Select the threshold operator.
Compare Value
Type the value to compare to the threshold.
Wait Cycle
Type a value for the wait cycle. vCenter Operations Manager multiplies the
wait cycle value by the collection interval to calculate the number of minutes
that a threshold must be out of bounds before generating an anomaly.
Cancel Cycle
Type a value for the cancel cycle. vCenter Operations Manager multiplies
the cancel cycle value by the collection interval to calculate the number of
minutes the metric must be in bounds before canceling an anomaly.
8 To make a violation of the hard threshold a KPI, select the Violation of the Hard threshold is a Key
Indicator check box and select the criticality level from the Select Criticality Level at which a Hard
Threshold becomes Key Indicator drop-down menu.
The criticality level indicates the level that must be reached for a violation to be considered a KPI breach.

Metric Data Types
Most of the data that vCenter Operations Manager stores and analyzes is numeric, but it can also track other
types of data and alert you if the values are unexpected.
For example, if a resource sends the string Good when operation is normal and Bad when a problem occurs,
vCenter Operations Manager analytics can learn this information and generate an anomaly when it receives
Bad.
Table 4-2. Metric Types
Data Type Description
common The attribute data is numeric. This is the most common type
of attribute.
multinomial The attribute data is one of a limited set of possible values,
either string or numeric.
sparse If you know that vCenter Operations Manager will not
receive data for an attribute on a regular basis, use the sparse
data type. Using the sparse data type prevents
vCenter Operations Manager from generating anomalies
when it does not receive the metric as expected.
Set the Data Type for an Attribute
By default, vCenter Operations Manager recognizes the type of data that it receives for each attribute. You can
override this behavior by explicitly setting the data type for an attribute in an attribute package.
IMPORTANT If you do not set the correct the data type, vCenter Operations Manager does not use the proper
analytic algorithms when it evaluates the metric.
Prerequisites
Become familiar with the metric data types. See “Metric Data Types,” on page 44.
