Statistics
This page displays the power consumption trend, which is the average power consumption
over time. This is useful for monitoring and debugging of PoE behavior.
The device stores PoE port consumption values (in units of watts) over time. This enables
calculating and displaying the average PoE consumption over specified time of day/week/
month, and enables detecting trends. Information is provided for each interface and for the
device as a whole.
PoE consumption readings are taken every 1 minute. The daily, weekly and monthly statistics
are saved in flash memory, so that they are still available after reboot.
A sample's average PoE consumption per port/device is as follows:
Sum of all PoE consumption readings in a period / Number of minutes in the sampling
period.
