Abstract

Information about the unavailability or incorrect operation of the service for the user, which is received in the form of a message or complaint to the center for collecting such information, is called an indirect feature of a failure.
Such information is generated by users of services that are not to have the aim in participating in studying the causes and eliminating the failure in the service.
The tasks of analyzing failures in large distributed information infrastructures by indirect features are relevant, since additional objective sources are involved in monitoring the infrastructure - users of services. The article builds a formal graph model of the information infrastructure (hereinafter, the system), which allows one to reflect information about the appearance of failures, taking into account their localization in the system, depending on the information content of indirect features. The conditions were found to detect the root cause of the failure at various levels of the hierarchical description of the system that means the identification of the aggregated object in which the root cause of the failure is located. The examples of propagation of failures and the usage of indirect features to analyze system malfunction during fault propagation are given.
