  • Patent number: 10887331
    Abstract: An information processing apparatus includes: a reach-extent extraction unit configured to extract, with use of a relationship graph representing relationships between a plurality of elements included in a system and location information that indicates, on the relationship graph, a plurality of locations in the system where anomalies have been detected, paths in the relationship graph as being reach extents, the path including a set of the elements that are directly or indirectly related to each of the plurality of locations as a source; and a shared-extent extraction unit configured to extract an influence process of an anomaly by extracting an extent that is shared in at least a prescribed number of paths among paths in the relationship graph that have been extracted as the reach extents.
    Type: Grant

  • Patent number: 10860406
    Abstract: The present invention provides an information processing device that outputs information including the data transmission relationship between elements constituting an information processing system, the information indicating the state of the information processing system. The information processing device includes a graphing means for generating a relationship graph based on an event log indicating the behavior of each of a plurality of processes operating in the system, the relationship graph having the processes as the vertices thereof and having the data transmission relationship between the vertices as the sides thereof; and a graph output means for outputting the generated relationship graph.

  • Patent number: 10789118
    Abstract: The present invention provides an information processing device that improves the detectability of system errors. This information processing device includes: a means that generates a state graph based on relationship change information indicating a change in the relationship between a plurality of elements included in a system, the state graph having the elements as the vertices thereof and the relationship between the elements as the sides thereof; a means that generates a normal model having the state graph as a set of conditions to be fulfilled during normal system operation, based on the relationship change information; and a means that detects system errors and outputs error information indicating detected errors, based on the state graph and the normal model.
