System, apparatus, and method for information processing

摘要

A system includes apparatuses and a power collecting device for collecting power consumption information at power sources to which the apparatuses are connected, respectively. The apparatus includes a controller that sets the apparatus to a first state or a second state for a lower power consumption; a first obtaining unit that obtains, from the device, first associated information in which first information for identifying the sources is associated with second information indicating power consumption of the respective sources; a retaining unit that retains second associated information in which the first associated information is associated with the time when the first obtaining unit obtains the first associated information; a state determining unit that determines a state of the other apparatus; and a second obtaining unit that obtains third associated information corresponding to a period during which the apparatus is in the second state when the apparatus transits to the first state.

主权项

1. An information processing system comprising:
a plurality of information processing apparatuses; and a power collecting device configured to collect pieces of power consumption information at a plurality of power sources connected to the plurality of information processing apparatuses, respectively; each of the information processing apparatuses including,
a memory having computer readable instructions stored thereon; andat least one processor configured to execute the computer readable instructions to,set the information processing apparatus to a first state or a second state based on at least one desired condition,
the second state including power consumption at the information processing apparatus being smaller than power consumption in the first state, and which indicates that communication with the power collecting device and the other information processing apparatuses cannot be performed while in the second state;regularly obtain, from the power collecting device, first associated information including pieces of first information for identifying the respective plurality of power sources associated with pieces of second information indicating power consumption of the plurality of respective power sources;retain second associated information in which the obtained first associated information is associated with temporal information indicating a time when the first associated information was obtained;determine a state of the other information processing apparatuses;obtain third associated information from the other information processing apparatuses when the information processing apparatus transitions from the second state to the first state, the third associated information indicating a portion corresponding to a period during which the information processing apparatus is in the second state, in the retained second associated information provided by the other information processing apparatuses determined to be in the first state;generate third information that indicates power consumption of each of the information processing apparatuses based on information in which the retained second associated information is combined with the third associated information; anda control displaying of the third information.
