Network monitoring system, network monitoring method, and program

A network monitoring method, comprising:

• monitoring, by IP network monitoring circuitry, an IP network to which a plurality of IP devices is connected, the plurality of IP devices in the IP network being configured to communicate via the IP protocol, wherein the monitoring by the IP network monitoring circuitry further comprises extracting a first failure that has occurred in the IP network according to a first pre-classified primary isolation cause, and extracting a root cause of the first failure based on the first primary isolation cause;
• and
• monitoring, by non-IP network monitoring circuitry, a non-IP device using particular data of the non-IP device received via the IP network and the IP network monitoring circuitry, wherein the non-IP device is not configured to communicate via the IP protocol with any IP device connected to the IP network, and the monitoring by the non-IP device monitoring circuitry further comprises extracting, using the received particular data of the non-IP device, a second failure that has occurred in the non-IP device according to a second pre-classified primary isolation cause, and extracting a root cause of the second failure based on the second primary isolation cause.
