Search of empirical causes of failures and errors in computer systems and networks using metadata

The management of distributed information and computing systems involves two interrelated tasks: business continuity and security. Both tasks use similar methods to identify the causes of failures and security incidents. The aim of the study is adequate formalization, which in the future can be used to automate at least part of the functions of search for causes of failures and security incidents. Based on the relationship between the functions of the system administrator and methods of building metadata for managing connections in distributed information and computing systems, the method of hierarchical building of metadata and the new method of their application are proposed, which allows to search for causes of failures and control the solution of problems in such systems. The model and algorithm of search for an empirical cause of the failure, which are based on metadata and backup of tasks and data, have been built. It is shown that it is possible to build a tree of solutions to identify an empirical cause of an implicit failure with accuracy to an available destabilization of failed information technology. This highlights typical cause-effect analysis tasks from which you can design the entire search.
