From Grid5000
Jump to: navigation, search

From September 2018, electrical power consumption of all nodes in Lyon is monitored by new "wattmetre" devices from Omegawatt, enhancing old wattmetres previously available.

For each plug supplying electrical power to Lyon nodes, the wattmetre devices perform up to 50 measurements of the power consumption per second.

Their usage is described in the Energy_consumption_monitoring_tutorial.

Monitoring data from the old wattmetre server is archived and accessible under /grid5000/wattmetre-archives directory of Lyon site.

The mapping between wattmetre ports and monitored hosts is described in the reference API. However, some information are not present yet:

  • Wattmetre 3, port 25 & 26: hercule cluster (the 4 nodes share 2 PSU)
  • Wattmetre 3, port 28: force10 network switch
  • Wattmetre 3, port 29 & 30: wattmetre monitoring server
