Abstract: The subject matter of this specification can be embodied in, among other things, a method that includes supplying power to a portion of a data center through a power distribution line. Utilization of a statistically significant sample of the computers is monitored, and an estimated individual power draw for each of the computers based on the utilization is calculated.

Abstract: A first alert and a second alert are received. The first alert indicates a first fault related to a first component of the multiple components and the second alert that indicates a second fault related to a second component of the multiple components. The first component affects the second component such that the first fault caused the second fault. A correlation between the first alert and the second alert is determined and, based on the determined correlation, a determination is made that the first fault is a root cause of the first alert and the second alert. An indication that the first fault is the root cause of the first alert and second alert is provided.

Abstract: In a computer-implemented method, an electronic communication from a first computing machine is received and includes a power value and one or more priority values. The power value represents a request for a power allotment expected to be used during a predetermined time and the priority values represent priorities of tasks expected to be executed during the predetermined time. A score for the request is calculated using a scoring function and the received priority values as inputs to the scoring function. The score is compared to one or more other scores respectively associated with requests for power allotments from other computing machines and previously calculated using the scoring function following receipt of one or more electronic communications each including a power value and one or more priority values. A top-ranked score is identified and an electronic communication is sent to the associated computing machine granting the requested power allotment.
