DETECTING ANOMALOUS STATES OF MACHINES
First Claim
1. A computer-implemented method for implementation by one or more data processors forming part of at least one computing device to facilitate the detection and avoidance of undesirable system states of a system, the method comprising:
- monitoring, by the one or more data processors, states of the system, the system comprising a plurality of components, the states of the system having state types and being translated into data instance groups;
receiving, by the one or more data processors, the data instance groups;
determining, by the one or more data processors, distributions of state types within the data instance groups to identify infrequent state types;
identifying, by the one or more data processors, rare states and rare sequences, where rare sequences include sequences of data instance groups that occur prior to the occurrence of a state having an infrequent state type; and
providing, by the one or more data processors, a notification of the occurrence of a rare sequence on the system.

Abstract
The state of a system is determined in which data sets are generated that include a plurality of data instances representing states of one or more components of a computer system. The data instances generated by one or more data set sources that are configured to output a data instance in response to a trigger associated with the one or more components. The data instances are normalized by the application of one or more rules. The data instances from individual data set sources are separately collated to generate groups of time-specific collated data instances. State types may be assigned to each of the collated data instance groups. Distributions of state-types across the groups may be determined and a list of infrequent state-types may be generated based on the determined distributions of state-types across the groups.
