A Trend Log is a time-stamped historical record of a monitored value, such as a temperature, pressure or power reading, sampled at regular intervals by a BMS, DCIM or EPMS. Operators use trend logs to analyze equipment behavior over time, diagnose faults, verify setpoint stability and support energy optimization and commissioning.
