With the transition of modern internet platforms

With the transition of modern internet platforms to a microservice architecture, the task of monitoring the technical health of a system has become several times more complex. When a single application is divided into dozens of isolated services, abnormal behavior in one module inevitably impacts the user experience. If a client encounters an error when attempting to activate a bonus or launch a game, engineers find it extremely difficult to isolate the problem by checking local logs on each server individually. The solution to this problem is the implementation of centralized and distributed logging systems. A detailed analysis of the IT stack for collecting system metrics is available at https://liraluck-casino.com . In high-load projects, the ELK stack (Elasticsearch, Logstash, Kibana) or its modern alternative, Grafana Loki, has become the industry standard for collecting and analyzing system events. Special lightweight collection agents (such as Filebeat) are installed on all application servers and forward text logs in real time to a unified processing pipeline. There, raw data is structured, indexed, and stored in a powerful search database. Using Kibana's user-friendly graphical interface, IT specialists can view a complete timeline of events occurring in the system at the time of the failure with a single click.
