• an obtaining unit configured to obtain first abnormality information indicating an abnormality caused in the first network and second abnormality information indicating an abnormality caused in each of the second nodes;
• a first output unit configured to output, for each of the second nodes, a communicating status and an operating status of the second node in the first network;
• and
• a second output unit configured to extract, in response to selection of the output communicating status of one of the second nodes, the abnormality caused in the selected second node from the first abnormality information and output information about the extracted abnormality, and in response to selection of the output operating status of one of the second nodes, extract and output the second abnormality information corresponding to the selected second node.
