Installation guide

If a component is functioning normally, the status indicator is green. The status indicator changes to yellow
or red if a system component violates a performance threshold or is not functioning properly. Generally, a
yellow indicator signifies degraded performance. A red indicator signifies that a component stopped operating
or exceeded the highest threshold. If the status is blank, then the health monitoring service cannot determine
thae status of the component.
The Reading column displays the current values for the sensors. For instance, the column displays rotations
per minute (RPM) for fans and degrees Celsius for temperature.
