The JINR Tier-1 for CMS was created in 2015. It is important to keep an eye on the Tier-1 center all the time in order to maintain its performance. The one monitoring system is based on Nagios: it monitors the center on several levels: engineering infrastructure, network, and hardware. It collects many metrics, creates plots and determines hardware components states like HDD states, temperatures, loads and many other. But this information is not always enough to tell if the Tier-1 services are working properly. For that purpose, a service monitoring system was developed in order to collect data from different resources including WLCG monitoring services. The purpose of this system is to aggregate data from different sources, determine states of the services based on new and historical data and react according to some predefined instructions. The systems, general idea, and architecture are described and analyzed in this work
