6 Double-click the AvgCPUtil attribute.
The database ID of the resource and metric appear in the formula line at the top of the window.
7 (Optional) To see the resource name and metric name, click below the formula line.
8 Click OK to save the super metric.
9 Add the super metric to an existing super metric package, or create a new super metric package.
10 Assign the super metric package to the tier.
Configure Weighted Metric Groups
With the weighted metric groups feature, vCenter Operations Manager calculates the weight of individual
metrics based on the number of metrics in the group so that every top-level group has equal weight in the
health calculation.
When the weighted metric groups feature is enabled, the total anomalies metric shows the weighted total
anomalies that are related to the total number of metrics. When the weighted metric group feature is
disabled, each metric has equal weight when vCenter Operations Manager calculates health, for example,
two CPU metrics have the same effect on health as two memory metrics.
Procedure
1 Open the analytics.properties file in the vcenter-ops\user\conf\analytics directory.
The vCenter Operations Manager vApp uses the analytics.properties file on the Analytics virtual
machine.
2 To enable or disable weighted metric groups, set the useMetricGroupWeightingForHealth property to
true or false.
3 Save your changes and close the analytics.properties file.
4 Restart the Analytics service to make your changes take effect.
Prioritize Threshold Checking
You can pause dynamic threshold calculation when the data queue size exceeds a certain value. This feature
enables you to prioritize threshold checking over the dynamic threshold calculation.
Procedure
1 Open the advanced.properties file in the vcenter-ops\user\conf\analytics directory.
2 Set the dtBlockIfDataQueueSizeOver property to the data queue size.
For example: dtBlockIfDataQueueSizeOver = 200
NOTE Setting the dtBlockIfDataQueueSizeOver property to 0 disables the feature.
3 Save your changes and close the advanced.properties file.
4 Restart the Analytics service.
Enable the Combined Dynamic Threshold Plug-in
The combined dynamic threshold plug-in provides faster and more accurate dynamic threshold calculations
by combining the information learned from all previous dynamic threshold algorithms.
Procedure
1 Open the advanced.properties file in the vcenter-ops\user\conf\analytics directory.
