Master device, slave device, information processing device, event log collecting system, control method of master device, control method of slave device and control program

A slave device, adapted to communicate with a master device for acquiring a moment, and record generation of a specified event, and the slave device comprising:

• a timer element, counting a current moment;
• a moment information receiving element, receiving a moment information from the master device, corresponding to the moment acquired by the master device;
• a moment adjustment element, synchronizing the moment counted by the timer element according to the moment information received by the moment information receiving element;
• and
• a log sending element, sending a first event log to the master device, wherein the first event log is an information formed by associating a generation moment of the event with an information for determining the event.

A control method of a master device, wherein the master device is adapted to communicate with at least one slave device for recording generation of a specified event, the control method of the master device comprising:

• a moment acquiring step, acquiring a moment;
• a moment adjustment instructing step, making the slave device to synchronize a moment counted by the slave device and the moment acquired in the moment acquiring step by sending a moment information corresponding to the moment acquired in the moment acquiring step;
• and
• a log receiving step, receiving a first event log from the slave device, wherein the first event log is an information formed by associating a generation moment of the event with an information for determining the event.

A control method of a slave device, wherein the slave device is adapted to communicate with a master device acquiring a moment, and record generation of a specified event, and the control method of the slave device comprising:

• a time counting step, counting a current moment;
• a moment information receiving step, receiving a moment information from the master device, corresponding to the moment acquired by the master device;
• a moment adjustment step, synchronizing the moment counted in the time counting step according to the moment information received in the moment information receiving step;
• and
• a log sending step, sending a first event log to the master device, wherein the first event log is an information formed by associating a generation moment of the event with an information for determining the event.
