This read-only value reports the current temperature reading, in the CoriantTypesTemperature format, at the monitoring point named by the sibling temperatureDetailsMonitoringPoint object. Operators poll this to catch thermal drift before it causes a shutdown or optical performance degradation, especially on high-power coherent optics cards. For example, a rising reading at the DSP-chip-internal point from 60C toward 85C over several polling cycles would warn an operator of a cooling-fan problem well before the card auto-protects itself.
