The vCenter Server Appliance API offers health status indicators for several key components of the appliance. These indicators can be polled periodically to monitor the components for problems.

The health status indicators report graded values from green to red. The general meanings of the grades are as follows.

green

The component is healthy.

yellow

The component is healthy, but may have some problems.

orange

The component is degraded, and may have serious problems.

red

The component is unavailable, or will stop functioning soon.

gray

No health data is available.
