description: The subject if the graduate work is âDevelopment of fault-tolerant distributed monitoring system for data storage systemâ.
The given work is devoted to the research of existing solutions for building a monitoring system for complex technical systems, as well as the design and development of a solution that provides reliable storage of metrics, high availability, and fault-tolerance at partial degradation of the system.
The work was carried out based on the existing product. The original solution provided the necessary requirements but had extremely low performance and imposed restrictions on the number of stored metric values.
In order to increase the storage efficiency of metrics and increase their number, without compromising the reliability of the entire system, a new solution was designed and implemented, which is based on the use of a time-series database. To ensure reliability and availability, a standard approach is used for systems consisting of several nodes - duplication of components. To achieve the goal, tools have been developed that ensure data consistency between multiple database instances and allow you to get consistent query results from all copies of the database. The results of testing this solution showed a high potential for further use in the existing system.
