3 On the Alerts tab, review the list and the information given for each alert.
You can use the columns and filters to sort the alert list.
The alert information provides actionable data for identifying and resolving a problem. For example, it shows
whether a resource is unavailable or running out of capacity. You can address the problem in the vSphere
Client.
Finding Problems in the Virtual Environment
When you log in to vCenter Operations Manager, examine the badges and graphs on the Dashboard tab to
determine if problems exist.
The Dashboard tab provides an overview of your virtual environment. The Health badge indicates immediate
issues.
In addition, the Stress badge, which is a component of the Risk badge, shows the objects in the virtual inventory
that have habitual high workloads that you might need to adjust.
n
Identify an Overall Health Issue on page 37
The Health badge is the indicator of a potential problem in the virtual environment that
vCenter Operations Manager monitors.
n
Identify Objects with Stressed Capacity on page 38
Identify the stressed virtual machines, hosts, and clusters that might require more capacity.
n
Identify Stressed Hosted or Clusters for Load Balancing on page 38
Identify the stressed or undersized hosts and clusters to assign more capacity to those objects and
optimize the load.
Identify an Overall Health Issue
The Health badge is the indicator of a potential problem in the virtual environment that
vCenter Operations Manager monitors.
By default, the Dashboard tab displays information about the World object. You can select another object in
the inventory pane to check for immediate health problems on the object. (You can also use the Search text box
at the upper right, entering part or all of the object's name, to locate an object.)
Prerequisites
In the vCenter Operations Manager interface, verify that the Dashboard tab is open.
Procedure
1 On the Dashboard tab, check the color of the Health badge.
2 If the color of the Health badge is other than green, click the arrow under the badge to expand the detailed
view.
The Health pane displays the sub-badges for Workload, Anomalies, and Faults. Badge colors help you
identify the possible cause of the problem.
