Lyon:Wattmetre

From September 2018, electrical power consumption of every nodes at Lyon is monitored by new "wattmetres" devices, enhancing old wattmetres previously available.

For each plug supplying electrical power to Lyon nodes, wattmetres perform up to 50 measurments of the power consumption each second.

Accessing monitoring data

	Warning
	Subject to change! API and URLs to access monitoring data are likely to change in the future.

From Kwapi

Wattmetre data is available using Kwapi. See TODO for more information. There is no changes in data stored in Kwapi compared to the old wattmetres: it still stores the average power consumption each second for every Lyon's nodes

Getting access to raw values

The "raw" data collected by wattmetres, including the 50 measurements made each second, is stored in CSV files and available for download at: TODO

TODO: Explain how mapping between nodes and (wattmetre, port) in CSV files is described in Ref API.

Getting "live" values directly from wattmetres

Live energy monitoring previously provided by "old" wattmetres remains available at URL http://wattmetre.lyon.grid5000.fr/GetWatts-json.php

It still provides for each node the average electrical power consumed during the latest second of measurements.

Getting access to old wattmetre data

Raw monitoring data stored on old wattmetre server is archived and accessible under /grid5000/wattmetre-archives at from Lyon site.
