This INTEGER is the lowest temperature in degrees Celsius that the front-mezzanine/IO-area temperature sensor on the blade motherboard recorded during the sampling window covered by this live reading. Comparing this minimum to the maximum for the same sensor tells an admin how much that specific spot's temperature swung during the interval, which flags an intermittent cooling issue that a single average would smooth over. A min of 32°C paired with a much higher max in the same record suggests the sensor briefly ran hot before airflow (or fan ramp-up) brought it back down.
