This window lists the sensor data records for fans, CPUs, and the motherboard present in the SBC chassis.

To view sensor details, navigate to:

Monitoring > Dashboard > Sensors or
Monitoring > System > Category: Hardware Status > Sensors

The Sensors window opens and consists of the following panes:

  • Sensor Data Records : Specifies the list of sensor data records.
  • Sensor List : Specifies the list of sensor data records and also data for each.

The following columns are displayed in the Sensor List pane:

ParameterDescription
SensorName of the sensor.
ValueCurrent sensor value.
UnitMeasurement terms (degree for temperature, discrete for signals, RPM (revolution per minute) for fans).
Status

Current status of the sensor

  • ok-good
  • na- not available
  • 0x0100- not reliable
  • 0x0200 – reliable
  • nc- non critical
UNRUpper Non Recoverable. Critical state, need to take immediate action.
UCRUpper Critical Recoverable. Slightly greater than upper threshold, which is critical but recoverable.
UNCUpper Non Critical. Upper threshold value, but not critical.
LNC

Lower Non Critical. Lower threshold value, but not critical.

LCRLower Critical Recoverable. Slightly lower than lower threshold critical, but recoverable.
LNRLower Non Recoverable. Critical statistics, need to take immediate action.

The following entries are displayed in the Sensor List pane:

SensorDescription
MB/CPU1_REL_TEMPCPU1 Real Temperature. Each CPU has its own temperature rating.
MB/CPU2_REL_TEMPCPU2 Real Temperature, each CPU has its own temperature rating.
MB/US_NP_TEMPUpstream Network Processor temperature.
MB/DS_NP_TEMPDownstream Network Processor temperature.
MB/INLET_TEMPInlet temperature.
MB/CPU_HOT_INDThis signal triggers when the CPU is HOT.
MB/CPU_CAT_ERRCatastrophic indication signal. If the status is 0x0100, then the signal is not present and not reliable. If the status is 0x0200, then the signal is present and reliable.

MB/NP_TEMP_ALRT
