Using the Anomalies Badge Under the Health Badge
The vCenter Operations Manager Anomalies badge measures the extent of abnormal behavior for an object
based on historical metrics data. 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 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 grows. 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 involves the number of statistics that fall outside of the expected behavior trends while Workload
involves an absolute measurement of how hard an object works for resources. Both Anomalies and Workload
are useful when attempting to find a probable cause and troubleshooting performance problems.
The Anomalies score ranges between 0 (good) and 100 (bad). The badge changes its color based on the badge
score thresholds that are set by the vCenter Operations Manager administrator.

The Anomalies score is normal. No attention required.
The Anomalies score exceeds the
normal range.
Check and take appropriate
action.
The Anomalies score is very
high.
Check and take appropriate
action as soon as possible.
Most of the metrics are beyond
their thresholds. This object
might not be working properly
or will stop working soon.
Act immediately to avoid or
correct problems.
No data is available for any of
the metrics for the time period.
The object is offline.
A vCenter Operations Manager administrator can change the badge score thresholds. For example, a green
Anomalies badge can indicate a score below 60 instead of 50, as set be default.
Using the Faults Badge Under the Health Badge
The vCenter Operations Manager Faults badge measure the degree of problems that the object might
experience based on events retrieved from the vCenter Server.
The events that might generate faults include the loss of redundancy in NICs or HBAs, memory checksum
errors, high availability failover, or Common Information Model (CIM) events, which require your immediate
attention.
The Faults score ranges between 0 (no faults) and 100 (critical faults). The badge changes its color based on the
badge score thresholds that are set by the vCenter Operations Manager administrator.
