Abstract:
An information processing device collects information on an operating state of a communication system formed of a master device that manages communication over a network and at least one slave device connected to the network and capable of performing communication as instructed by the master device. The master device and the slave device record communication log entries regarding time information and a communication state in accordance with communication processing. The information processing device includes an acquiring section that acquires communication log entries from at least one of the master device and the slave device, a log entry rearranging section that rearranges the acquired communication log entries based on the time information, and a log entry extracting section that extracts, out of the rearranged communication log entries, any communication log entry recorded within a predetermined period of time from occurrence of a communication log entry including communication abnormality information.
Abstract:
An approach capable easily setting required connection settings even when multiple devices are connected to a network is provided. A support apparatus includes: a setting reception part, which receives a connection setting that is the setting of the connection established between the control apparatus and each remote device; and a transmission part, which transmit the connection setting received by the setting reception part to the control apparatus and the remote device which are involved in the connection setting.
