The Yellow- or Red-Highlighted Sensors
When a numeric sensor's reading enters the warning or critical range,
the background color of that sensor's row turns to yellow or red for
alerting you.
For a discrete (on/off) sensor, the row changes the background color
when the sensor enters the abnormal state.
See the table for the meaning of each color:
White The background is white in one of the following scenarios:
• For a numeric sensor, no thresholds have been
enabled.
• If any thresholds have been enabled for a numeric
sensor, the sensor reading is within the normal range,
which is between the lower and upper warning
thresholds.
• For a discrete (on/off) sensor, the sensor state is
normal.
• The sensor is unavailable or unmanaged.
Yellow The reading drops below the lower warning threshold or
rises above the upper warning threshold.
Red The meaning of the red color varies depending on the
sensor type:
• For a numeric sensor, this color indicates the reading
drops below the lower critical threshold or rises above
the upper critical threshold.
For a discrete (on/off) sensor, this color indicates the
sensor is in the "alarmed" state.
