In the following table, "R" represents any numeric sensor's reading. The symbol <= means “less than” or "equal to."
Sensor status
Color
States shown in the interface Description
Unknown
Transparent unavailable
Sensor state or readings cannot be detected.
unmanaged
Sensors are not being managed. See
Unmanaged Sensors/Dry Contacts
Note: Managed and unmanaged sensors applies only to
Peripherals.
Normal
Transparent normal
•
Numeric or state sensors are within the normal range.
-- OR --
•
No thresholds have been enabled for numeric
sensors.
Warning
Yellow
above upper warning
Upper Warning threshold < "R" <= Upper Critical threshold
below lower warning
Lower Critical threshold <= "R" < Lower Warning threshold
Critical
Red
above upper critical
Upper Critical threshold < "R"
below lower critical
"R" < Lower Critical threshold
Alarmed
Red
alarmed
State sensors enter the abnormal state.
Available sensor states:
The more thresholds are enabled for a sensor, the more sensor states are available for it. The "normal' state is always
available regardless of whether any threshold is enabled.
For example:
•
When a sensor only has the Upper Critical threshold enabled, it has two sensor states: normal and above upper
critical.
•
When a sensor has both the Upper Critical and Upper Warning thresholds enabled, it has three sensor states: normal,
above upper warning, and above upper critical.
States of "above upper warning" and "below lower warning" are warning states to call for your attention.
States of "above upper critical" and "below lower critical" are critical states that require you to immediately handle.
