Grenoble:Wattmetre

The electrical power consumption of all nodes in Grenoble is monitored by wattmetre devices from Omegawatt (same as nodes in Lyon).

Up to 50 measurements per second are recorded for all power supply units of all nodes.

For now, only the yeti nodes are supported by the full featured tools described in the Energy_consumption_monitoring_tutorial.

The dahu nodes are more complex in the fact that they are grouped in chassis of 4 nodes, with 2 power supply units per chassis.

The power consumption information for the dahu is for now limited to the csv files, as described [[1]], for instance:
