Table 2-3. Object Workload States
Badge Icon Description User Action
Workload on the object is not
excessive.
No attention required.
The object is experiencing some
high resource workloads.
1 At the upper right of the
Health tab, click the View
details icon to open the
VMware vCenter Operations
Manager user interface.
2 Check the Details tab to
identify which resources
experience abnormal
workload.
Workload on the object is
approaching its capacity in at
least one area.
1 At the upper right of the
Health tab, click the View
details icon to open the
VMware vCenter Operations
Manager user interface.
2 Check the Details tab to
identify which resources are
limited, and take appropriate
action as soon as possible.
Workload on the object is at or
over its capacity in one or more
areas.
1 At the upper right of the
Health tab, click the View
details icon to open the
VMware vCenter Operations
Manager user interface.
2 Check the Details tab to
identify which resources are
exhausted. Act immediately
to avoid or correct problems.
No data is available.
The object is offline.
A vCenter Operations Manager administrator can change the badge score thresholds. For example, a green
Workload badge can indicate a score below 80 instead of 85, as set by default.
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.
