To add the the references, the following paper is very interesting: http://www.cs.pitt.edu/~kirk/cs3150spring2010/2008_asplos_nopowerstruggles.pd f The paper looks at the power savings that can be achieved by co-ordinated management of resources in the data center (including virtual machine place

The energy monitoring MIB proposals look like they might provide the required metrics. It is worth waiting to see the outcome of the March IETF meeting to see how they plan to proceed. Ideally the sFlow energy structure will be a simple XDR encoding of a standard set of values from an energy MI

Hi, Interestingly some other work has been happening around like the following; " Definiton of Managed Objects for Energy Manage" http://tools.ietf.org/html/draft-quittek-power-mib-00 " Power Consumption MIB for IP forwarding devices" http://www.ietf.org/id/draft-teraoka-powerconsumption-mib-01.

Sujay, Thanks for all the information. It would make sense to look for a common set of measurements that can be obtained from the broadest range of devices. sFlow provides a fairly high frequency push of counters, so you can probably get by with fairly simple measurements that are aggregated at

Hi, Agree, it does make sense to add counters carrying this energy/power related information. Assuming the target networks to monitor for power/energy measurements are Data-Centers. A little digging would reveal that there is more info besides the basic counters of KWhr & Temp which sFlow needs
