The information shown in the Anomalies tab is the anomalies reported when metric values fall outside their normal range. The Anomalies score is the percentage of all metrics that have abnormal behavior. Use the Anomalies value as an investigative tool when you are researching abnormal behavior or evaluating the general state of objects in your environment.

vRealize Operations Manager calculates dynamic thresholds for each metric that is collected for an object. vRealize Operations Manager also analyzes the number of metrics that are violating their dynamic thresholds, to determine trends and normal levels of threshold violations. Based on these trends, the Anomalies analysis score is calculated using the total number of threshold violations for all metrics for the selected object and its child objects.

The vRealize Operations Manager Anomalies badge score represents how abnormal the behavior of the object is, based on its historical metrics data. vRealize Operations Manager indicates Anomalies using a colored icon that is based on the defined badge score thresholds.

When evaluating badge scores, a high number of anomalies might indicate a potential issue. A low Anomalies score indicates that an object is behaving in accordance with its established historical parameters. Most or all of the object's metrics, especially its KPIs, are within their thresholds. Because changes in behavior often indicate developing problems, if the metrics of an object go outside the calculated thresholds, the anomalies score for the object increases. As more metrics breach the thresholds, anomalies continue to increase.

Violations by KPI metrics increase the Anomalies score more than violations by non-KPI metrics. A high number of anomalies usually indicates a problem, or at least a situation that requires your attention.

Anomalies involve the number of statistics that fall outside of the expected behavior trends, whereas Workload involves an absolute measurement of how hard an object works for resources. Both Anomalies and Workload are useful when you are attempting to find a probable cause and when troubleshooting performance problems.

The Anomalies score ranges between 0 (good) and 100 (bad). The badge score thresholds can by modified by an vRealize Operations Manager administrator.

See Managing and Administering Policies for vRealize Operations Manager to configure symptom thresholds for the Anomalies badge score.

Description

User Action

Icon for normal score of Anomalies.

The Anomalies score is normal.

No attention required.

Icon for medium level of Anomalies.

The Anomalies score exceeds the normal range.

Check the details and take appropriate action.

Icon for partially high level of anomalies.

The Anomalies score is very high.

Check the details and take appropriate action as soon as possible.

Icon for excessive level of anomalies.

Most of the metrics are beyond their thresholds. This object might not be working properly or might stop working soon.

Act immediately to avoid or correct problems.

Icon for unknown level of anomalies.

The object is offline or no data is available.

To view the Anomalies badge, click Environment in the left pane and select the object, click the Analysis tab, and click the Anomalies tab.

Anomalies Based on the Selected Inventory Object

Item

Description

Badge status

Anomalies status for the object based on the anomalies policy.

Anomalies Trend

How the badge value for the object has trended over time.

This trend view allows you to see behavior over time and to identify when a change in a badge value indicates a change on the object.

The trend data time value is based on the Data Range setting, which is defined in the Time analysis settings for the policy that is associated with the object.

Anomalies Breakdown

Breakdown of the compliance standards by alert.

To see the violated standards, click the row in the standard table. To limit the standards list, use the following buttons.

Violated Standards. Displays only the standards alerts where at least on symptom is triggered.

All Standards. Displays all the standards alerts.

Anomalies in Related Objects

Anomalies of the related objects.

Use the related objects to determine if any problems are affecting only the current object or are related objects experiencing problems.

Object Resources

Configured resources for the object.
