Maintenance apparatus, network apparatus, information visualization system, and information generation method

A maintenance apparatus comprising:

• at least one second memory storing instructions;
• and
• at least one second processor configured to execute the second instructions to:
• extract a visualization target item being an item of traffic information to be visualized from a visualization item file in which traffic information being used for generating a monitoring screen, that is generated based on traffic information generated in a network apparatus in response to transmission/reception of a signal, is described in a predetermined file format;
• and
• notify the network apparatus of the extracted visualization target item and cause the network apparatus to initialize, with an initial value of 0, traffic information of the visualization target item.

An information generation method comprising:

• acquiring a visualization target item being an item of traffic information to be visualized, the visualization target item being extracted from a visualization item file in which traffic information being used for generating a monitoring screen, that is generated based on traffic information generated in response to transmission/reception of a signal, is described in a predetermined file format;
• initializing, with an initial value of 0, traffic information of the acquired visualization target item;
• and
• generating the traffic information, based on a signal transmitted/received in a network apparatus.
