Prometheus Exporter for colocation PDUs
This exporter is tailor-made for tracking power consumption of colocated servers at the Mechanical Engineering Campus of Leibniz University Hannover.
At the moment this service provides power and energy statistics for Rittal PDU-Controller, PDU-Man and Bachmann BlueNet2 PDUs. Rittal LCP support coming soon.
To avoid confusion keep in mind:
...a kilowatt is a unit of power but a kilowatt-hour (1 kilowatt times 1 hour) is a unit of energy.
More information can be found at the Website for Energy Education.
The total wattage drawn through the PDU in its service time, in kWh.
The current wattage being drawn through the PDU.
