Operating information storing system, operating information storing method, and non-transitory computer readable recording medium storing an operating information storing method for storing information from volatile memory to non-volatile memory

An operating information storing system includes a master apparatus and multiple slave apparatuses. The master apparatus and each slave apparatus respectively include a first processor. The master apparatus includes a nonvolatile memory, the first processor that acquires operating information generated by each slave apparatus, stores the acquired operating information, and determines if at least one operating information indicates specific operating information, and a first transmitter. Each slave apparatus includes a volatile memory, a second processor to store generated operating information in the volatile memory sequentially, and a second transmitter that transfers the operating information stored in the volatile memory to the master apparatus. The second processor stores the specific operating information in the volatile memory until the second transmitter transfers the generated specific operating information to the master apparatus based on the request transferred by the first transmitter in the master apparatus if the specific operating information is generated.
