Abstract
An information processing apparatus includes a candidate generating unit and a correcting unit. The candidate generating unit generates, using first log information indicating states of a monitoring target and acquired in a certain time period, a frequently appearing transition path of states of the monitoring target, as a candidate of a first path that is a transition path presumed to represent a first specific condition. The correcting unit obtains the first path by correcting the candidate using a predetermined reference path.
Claims14
An information processing apparatus comprising:
- one or more hardware processors configured to function as:
- a candidate generating unit that generates, using first log information indicating states of a monitoring target and acquired in a certain time period, a frequently appearing transition path of states of the monitoring target, as a candidate of a first path that is a transition path presumed to represent a first specific condition;
- a correcting unit that obtains the first path by correcting the candidate using a predetermined reference path;
- and
- an extracting unit that extracts a deviating path not conforming to the first path, from second log information indicating states of the monitoring target, the second log information being obtained in a determination time period for which a determination is made as to whether the monitoring target is in a second specific condition, the determination time period being a period for which an abnormal sign detection is performed, the abnormal sign detection detecting an abnormal sign from the second log information using the first path.
An information processing method executed by an information processing apparatus, the method comprising:
- generating, using first log information indicating states of a monitoring target and acquired in a certain time period, a frequently appearing transition path of states of the monitoring target, as a candidate of a first path that is a transition path presumed to represent a first specific condition;
- obtaining the first path by correcting the candidate using a predetermined reference path;
- and
- extracting a deviating path not conforming to the first path, from second log information indicating states of the monitoring target, the second log information being obtained in a determination time period for which a determination is made as to whether the monitoring target is in a second specific condition, the determination time period being a period for which an abnormal sign detection is performed, the abnormal sign detection detecting an abnormal sign from the second log information using the first path.
A computer program product having a non-transitory computer readable medium including programmed instructions stored thereon, wherein the instructions, when executed by a computer, cause the computer to perform:
- generating, using first log information indicating states of a monitoring target and acquired in a certain time period, a frequently appearing transition path of states of the monitoring target, as a candidate of a first path that is a transition path presumed to represent a first specific condition;
- obtaining the first path by correcting the candidate using a predetermined reference path;
- and
- extracting a deviating path not conforming to the first path, from second log information indicating states of the monitoring target, the second log information being obtained in a determination time period for which a determination is made as to whether the monitoring target is in a second specific condition, the determination time period being a period for which an abnormal sign detection is performed, the abnormal sign detection detecting an abnormal sign from the second log information using the first path.
An information processing apparatus comprising:
- one or more hardware processors configured to function as:
- a candidate generating unit that generates, using first log information indicating states of a monitoring target and acquired in a certain time period, a frequently appearing transition path of states of the monitoring target, as a candidate of a first path that is a transition path presumed to represent a first specific condition;
- and
- a correcting unit that obtains the first path by correcting the candidate using a predetermined reference path, wherein
- the reference path includes a predetermined addition path as a path to be added to the candidate, and
- the correcting unit obtains the first path by adding the addition path to the candidate.
