vmware : what do red, green, yellow, unknown status indicate?
These are status indicators passed through the vmware probe coming directly from the ESX host and/or VCenter.
From the VMWare SDK?API:
http://pubs.vmware.com/vi-sdk/visdk250/ReferenceGuide/vim.host.HardwareStatusInfo.Status.html
Enum Description
The current status of the hardware
Enum Constants:
=================
Green: The physical element is functioning as expected
Red: The physical element is failing. It is possible that some or all functionalities of this physical element is degraded or not working.
Unknown: The implementation cannot report on the current status of the physical element
Yellow: All functionality is available but some might be degraded.
Basically, it?s a general health status.? However, there does not appear to be any document that describes what conditions would make a CPU (for example) go from green to yellow, etc.
Further detail would need to come from VMWare support.
