## Abstract

A network information collection device is provided, which connects, for example, artificial intelligence with each of a plurality of systems in one-to-one relationships. It includes an information collection and accumulation unit 10 which collects and accumulates information from each of management systems 71 to 75 for managing a plurality of devices constituting a network, a related information generation unit 20 which generates related information by associating connection relationships of the plurality of devices managed by the management systems 71 to 75 with the information, and a delivery unit 30 which delivers the related information to the outside with a specified granularity, the related information generation unit 20 includes a log aggregation unit 21 which records changes in a state of each of the plurality of devices, an inter-layer association unit 22 which associates the inter-layer connection relationships of the devices with the information, and a chronological arrangement unit 23 which chronologically arranges the changes in the states recorded in the log aggregation unit 21 and the information.

## Claims

### Claim 1

A network information collection device comprising one or more processors configured to perform:
a collecting and accumulating information from each of management systems for managing a plurality of devices constituting a network,
obtaining inter-layer connection relationships of the plurality of devices by referring to topology information of the plurality of devices based on IP addresses accompanying the information,
a generating related information by associating the obtained inter-layer connection relationships of the plurality of devices with the information, and
a delivering the related information to outside with a specified granularity.

### Claim 2 (depends on 1)

The network information collection device according to claim 1, wherein generating the related information comprises
a recording changes in a state of each of the plurality of devices,
a associating the inter-layer connection relationships of the devices with the information, and
a chronologically arranging the recorded changes in the states and the information.

### Claim 3 (depends on 1)

The network information collection device according to claim 1, wherein the one or more processors are further configured to perform:
