Grenoble:Wattmetre
- The electrical power consumption of all nodes in Grenoble is monitored by wattmetre devices from Omegawatt (same as nodes in Lyon or Nancy).
Up to 50 measurements per second are recorded for all power supply units of all nodes.
For now, only the yeti and troll nodes are supported by the full featured tools described in the Energy consumption monitoring tutorial, not the dahu nodes.
Dahu row measures
Each troll node has a single power supply unit (PSU) and each yeti node has redondant power supply units.
But 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.
As a consequence, the power consumption information for the dahu nodes is limited to the CSV files, as described in this section of the tutorial.
The row files of measures are located here: http://wattmetre.grenoble.grid5000.fr/data/ (only accessible from within the Grid'5000 network, or using Grid'5000 VPN).
For instance, one CSV line of measures is:

"OK" means that the measure is good, and is preceded by the time-stamp of the measure. Watt values begin after the OK, with 30 values as follows:
