Get List of Support Sensors
BlueField sensors are stored within the Sensors schema under the Chassis schema. To retrieve the list of supported sensors, execute the following command:
curl -k -u root:'<password>' -H 'Content-Type: application/json' -X GET https://<bmc_ip>/redfish/v1/Chassis/Card1/Sensors
The following is an example of the anticipated output:

Get Data for Specific Sensor
curl -k -u root:'<password>' -H 'Content-Type: application/json' -X GET https://<bmc_ip>/redfish/v1/Chassis/Card1/Sensors/<sensor_name>
The following is an example of a temperature sensor BlueField reading:

Configure Sensor Thresholds
The following commands set the thresholds for sensors that support setting a threshold:
curl -k -u root:'<password>' -X PATCH https://<bmc_ip>/redfish/v1/Chassis/Card1/Sensors/<sensor name>/ -d '{"Thresholds":{"<Threshold name>": {"Reading":<value>}}}'
The following is an example of how to set the upper critical threshold for the BlueField temperature sensor:
curl -k -u root:'<password>' -X PATCH https://<bmc_ip>/redfish/v1/Chassis/Card1/Sensors/bluefield_temp -d '{"Thresholds":{"UpperCritical": {"Reading":100}}}'
{
"@Message.ExtendedInfo": [

}
]
}
BMC software supports reading chassis sensor information using the IPMItool.
The following table lists commands which allow reading SDR data:
|
Command |
Description |
|
Displays sensor data repository entry readings and their status |
|
Displays extended sensor information |
|
Displays sensors and thresholds in a wide table format |
|
Displays information for sensor data records specified by sensor ID |
|
Displays all records from the SDR repository of a specific type |
|
Displays information for sensors specified by name |
|
Displays readings for sensors specified by name (only for numeric sensors) |
|
If a threshold is crossed, a message is added to the Redfish event log, SEL, and journal. |
