What to do next
On the Details tab under the Operations tab, you can check metric values to identify the resource that might
be causing the high Anomalies score. Depending on which resource indicates abnormal operation, check the
Key Metrics pane for further information.
Identify the Source of Performance Degradation
Identifying the probable source of performance degradation in vCenter Operations Manager involves
investigating the percentage of CPU, memory, disks, and network resources usage in the virtual environment.
Prerequisites
Verify that you are logged in to a vSphere Client and that vCenter Operations Manager is open.
Procedure
1 In the inventory pane, select the object that you want to inspect.
2 Click the Environment tab under the Operations tab, and select the Workload badge.
3 To filter the objects and related objects by state, click the Status Filter buttons to view only the red, orange,
and yellow states.
4 Point to the object state other than green to view the workload details.
5 Double-click a related object to investigate why it is experiencing heavy resource demands.
6 On the Details tab under the Operations tab, you can check the percentage of resource use that might be
causing the high Workload score.
7 To locate the available resources of the object and related objects, click the Scoreboard tab under the
Operations tab, and select the Workload badge.
The Scoreboard tab displays the workload scores for all ESX hosts in the cluster. By default, ESX hosts
with a high workload are presented as large badges.
8 To filter the objects and related objects by state, click the Status Filter buttons to view only the red, orange,
and yellow states.
9 Click the object that indicates a poor score.
10 On the Details tab under the Operations tab, review the Resources pane and the Workload graphs to
assess the potential capacity to move virtual machines to balance the workload.
What to do next
Click the Analysis tab to compare the performance of selected objects across the virtual infrastructure. You
can use this information to balance the load across ESX hosts and virtual machines.
Identify Events that Occurred when an Object Experienced
Performance Degradation
Identifying when the abnormal events started to cause performance degradation and the trend of the problem
in vCenter Operations Manager involves examining the Health scores of the object and its related objects.
In the Events tab under the Operations tab, you can view graphs of health-related badge scores and events
that occurred on the selected object and its related objects. When you notice that the score of a badge changed
after an event occurred, you can click that event to view more details.
Prerequisites
Verify that you are logged in to a vSphere Client and that vCenter Operations Manager is open.
