Development of Monitoring Service for BM@N Information Systems

Abstract

The software infrastructure of the BM@N experiment contains a set of various information systems that are essential for the work with experimental and simulated data on all processing stages, including the collection, storage, intermediate processing and physics analysis. Some examples of the systems are the Electronic Logbook Platform, Condition Database and Event Metadata System. In case one of such systems stops functioning, the work with BM@N data by collaboration members gets either impossible or, at least, much less productive. Due to this fact, the timely detection of possible failures in the systems because of software or hardware failures is fairly important. The developed Monitoring Service is used to check the availability and health status of the information systems. This includes measuring, storing, visualizing monitored parameters, such as CPU, memory and disk utilization, DBMS functioning parameters, response times of databases and API endpoints, ping round-trip times, as well as sending alert notifications in case of malfunctions. The current implementation of the BM@N Monitoring Service is presented in detail. A related task of building highly available information services is also briefly noted.
