The Key Health Indicators (KHI) feature provides a subset of health information that allows for quick assessment of the overall operational state of the device.

Note
KHI was not designed to provide a comprehensive debugging solution. Instead, KHI identifies key information that could lead support personnel towards discovery of a specific failure. After the technician assesses the KHI information, further debugging is required to determine the specific reason for the fault.
Capture KHI information during normal operations to provide a baseline for support personnel when detecting fault situations.
