Patent number: 11989083Abstract: A method for determining at least one machine involved in an anomaly detected in a computing infrastructure comprising a plurality M of machines. This determination is performed by associating with each machine a state vector constructed using metrics and logs. Each vector is also associated with a time window. The monitoring of these vectors makes it possible to detect an anomaly that is then explained via an explanation method that makes it possible to assign an involvement indicator to each machine. The use of this indicator makes it possible to determine the machine most involved.Type: GrantFiled: January 25, 2022Date of Patent: May 21, 2024Assignee: BULL SASInventors: Pierre Seroul, Emeric Dynomant, Maxence Menager
