Name: IPMI value for sensor {#SENSOR_ID}
As type of information, Numeric (unsigned).
In the item prototype “Preprocessing” tab select JSONPath and use the following JSONPath expression as parameter:
When discovery starts, one item per each IPMI sensor will be created. This item will return the integer value of the given sensor.
