INFORMATION COLLECTION APPARATUS, METHOD, AND PROGRAM
First Claim
1. An information collection apparatus which collects, from a plurality of devices each having a plurality of states including a power-supply state indicating ON or OFF of a power-supply, state information indicating a state of each device, the apparatus comprising:
- a first memory to store the power-supply state of each device;
a nonperiodic collection unit configured to receive state information transmitted from each device whose state is changed;
a first update unit configured to rewrite, when a power-supply state information indicating the power-supply state is obtained by the nonperiodic collection unit, the power-supply state stored in the first memory in accordance with the obtained power-supply state information;
a first periodic collection unit configured to collect the state information from each device whose power-supply state stored in the first memory is ON by issuing, at regular intervals, a first request for the state information to the device; and
a transmission unit configured to transmit the state information collected by the first periodic collection unit to an external apparatus.

Abstract
An information collection apparatus which collects, from a plurality of devices each having a plurality of states including a power-supply state indicating ON or OFF of a power-supply, state information indicating a state of each device, the apparatus (a) stores, in a first memory, the power-supply state of each device, (b) receives state information transmitted from each device whose state is changed, (c) rewrites, when a power-supply state information indicating the power-supply state is received, the power-supply state stored in the first memory in accordance with the obtained power-supply state information, (d) collects periodically the state information from each device whose power-supply state stored in the first memory is ON by issuing, at regular intervals, a first request for the state information to the device, and (e) transmits the state information collected periodically to an external apparatus.
