Performance and reliability analysis of an e-commerce platform monitoring system based on Prometheus and Grafana

A Python-based monitoring service for user metrics interacting with an open marketplace API has been developed. The architecture is implemented using Prometheus and Grafana and is focused on monitoring the performance of key stages of data processing: the number of requests, errors, response time, database write speed, and product characteristics. To assess system resilience, failure scenarios were simulated, including external API outages, database degradation, network delays, increased load, and memory leaks. The use of stream data processing in combination with SQLite ensures high performance and reliability.
