The Yellow- or Red-Highlighted Sensors
When a numeric sensor's reading crosses any upper or lower threshold, the background color of the whole row turns to yellow or red for alerting users.
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:
Color
|
State
|
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 falls between the lower and upper warning thresholds.
- For a discrete (on/off) sensor, the sensor state is normal.
- The sensor is unavailable.
|
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.

To find the exact meaning of the alert, read the information shown in the State (or Status) column:
- below lower critical: The numeric sensor's reading drops below the lower critical threshold.
- below lower warning: The numeric sensor's reading drops below the lower warning threshold.
- above upper critical: The numeric sensor's reading reaches or exceeds the upper critical threshold.
- above upper warning: The numeric sensor's reading reaches or exceeds the upper warning threshold.
- alarmed: The discrete sensor is NOT in the normal state.
