Meter Update Time

Power meter sampled time.

Three Hours Metered Value (MilliWattSec)

The "3 hours PoE energy" value, that is, the power consumed on the port for the 3 hour time period. The unit of this value is milliwatt-second.

Metered Energy in MilliWattSec (15min Buckets)

The "15 minutes PoE energy" values, that is, the power consumed on the port for successive periods of 15 minutes each, within the 3 hour time period. The unit of these values is milliwatt-second. These 12 values are for each of 15 minute buckets within the 3 hour period (15 minutes * 12 = 180 minutes = 3 hours).
