Hey,

I am looking for a solution to accurately determine the cost per month of my servers. Our city has SMART meters that charge different amounts at different times of the day. What is the best way to accurately measure power consumption and cost of a server. The SMB has 3 servers that are on 24 hours a day.

thanks

you may want to consider a meter to measure actual usage.

There is no V-app or anything that does this?....

There is no V-app or anything that does this?.... no because there are too many variables that cannot be measured i.e. power supply efficiency, fan efficiency, cooler efficiency, video card efficiency, of these the power supply is the most important and it doesn't directly connect to the motherboard in a (measurable way) just supply power to the motherboard.

Most business's cant take advantage of smart metering because they can't offload most tasks to the lower rate time frames. Turning off the servers during the peak usage times would not be to the business's advantage.  All you can do is add it to your variable costs of doing business.

Question makes a lot of sense; with a very smart UPS you could run the servers (plus the lights and kettle) on battery during the most expensive times and recharge the UPS when it's cheapest. You buy a UPS just to be able to shutdown the computers cleanly in the event of a power-out so you might as well make some savings on the electric bill by utilizing the overcapacity you undoubtedly specified because there isn't an exact fit UPS / managed PDU to fit the 5759 watt-minutes shutdown takes.

As to whether there's an app for that that Eaton or APC could write one easily, but first you have to buy their hulking great box of batteries in the form of an SNMP managed UPS.
