Patent ID: 8564818

Claim:
A log information management system including a plurality of image forming apparatuses for transmitting, via a network, a plurality of logs stored therein, and an information processing apparatus for receiving the logs from the plurality of image forming apparatuses and managing the received logs, wherein each image forming apparatus comprises at least one processor, functioning as: a log notification transmitting unit configured to notify the information processing apparatus that the image forming apparatus stores a log, wherein the log notification further includes power consumption information representing electric-power consumption of the image forming apparatus; a setting unit configured to set a log transmission time extracted from a response received from the information processing apparatus in response to the log notification; and a log transmission unit configured to transmit the log to the information processing apparatus at the set log transmission time, and wherein the information processing apparatus comprises at least one processor functioning as: a log notification receiving unit configured to receive the log notification from the image forming apparatus; a log transmission time determination unit configured to determine the log transmission time at which the image forming apparatus transmits the log; and a response unit configured to transmit, to the image forming apparatus, the response including the log transmission time determined by the log transmission time determination unit, wherein the log transmission time determination unit determines the log transmission time according to power consumption information included in the log notification received from the image forming apparatus so that a total amount of power consumption of one or more image forming apparatuses that transmit each log during the same time period is minimized.
