I am trying to find utilization or power consumption measurement of servers in time series. Is there any available online source of that? Thanks in advance
You can try to access any Solar Winds networks monitoring system with a huge number of Data Center Equipment then it will summarize this issue for you.
There are a number of places where you can search for the datasets such as kaggle, uci machine learning repository. But, I feel it is better to develop your own datasets catering to the context on which you are working.
