== 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 [[Energy_consumption_monitoring_tutorial#On_Lyon_site_and_Grenoble.27s_yeti_cluster|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:

The electrical power consumption of the yeti, troll, and servan clusters in Grenoble is measured by wattmetre devices from Omegawatt (same as nodes in Lyon or Nancy).
  • 50 measurements per second are recorded for every power supply unit of those clusters' nodes.
  • Each troll node has a single power supply unit (PSU)
  • Each yeti node and each servan node have redundant power supply units.
  • yeti and troll are monitored by the device named wattmetre-1, servan is measured by the device named wattmetre-2.
Note.png Note

Until 2022-09-01, the power consumption of the dahu cluster was also measured, although not available in kwollect (because measured by groups of 4 nodes). Dahu nodes aren't measured anymore due to hardware issues with the wattmetres (see the former version of this page for more information on the dahu measures).
