| ; The electrical power consumption of all nodes in Grenoble is monitored by wattmetre devices from [http://www.omegawatt.fr/ Omegawatt] (same as nodes in [[Lyon:Wattmetre|Lyon]] or [[Nancy:Wattmetre|Nancy]]). | | ; The electrical power consumption of the yeti and troll clusters in Grenoble is measured by wattmetre devices from [http://www.omegawatt.fr/ Omegawatt] (same as nodes in [[Lyon:Wattmetre|Lyon]] or [[Nancy:Wattmetre|Nancy]]). |

|
| Up to 50 measurements per second are recorded for all power supply units of all nodes.
| | 50 measurements per second are recorded for every power supply unit of those clusters' 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.
| | Each troll node has a single power supply unit (PSU) and each yeti node has redundant power supply units. |
|
| |
|
| == Dahu row measures == | | {{Note|text=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).}} |
| 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).
