Claim 3:
4. A network device information management method performed by a network device information management apparatus configured to manage inventory information about a plurality of devices connected to a network, the network device information management apparatus is configured to execute:
for each device included in the plurality of devices,
acquiring a first log data from the device at a first time, the first log data including information about components of the device;
acquiring a second log data from the device at a second time that is later than the first time, wherein a new component is registered to the device during a time period between the first time and the second time;
determining a log data common portion between the first log data and the second log data;
extracting a component configuration for the new component by excluding the log data common portion from the second log data;
comparing the extracted component configuration with a second component configuration extracted from a second component registered to a second device;
determine a component configuration common portion between the extracted component configuration and the second component configuration, wherein the component configuration common portion comprises a package type, a model number, and a version number;
estimating the component configuration common portion as inventory information of the new component registered on the device; and
storing the estimated inventory information of the new component registered on the device in a storage medium.
