In the era of microservices architecture, monitoring and maintaining performance is crucial for seamless operation and user satisfaction. Application Performance Monitoring (APM) and Realtime User Monitoring (RUM), when integrated with Elasticsearch, provide comprehensive insights into both server-side and client-side performance. APM captures detailed metrics on response times, error rates, and throughput across various microservices, enabling real-time analysis and issue diagnosis. RUM focuses on the end-user experience, gathering data on page load times and user interactions directly from users' browsers. This integration allows for unified monitoring, scalable data handling, customizable dashboards, and proactive issue resolution, ensuring your microservices architecture operates efficiently and delivers a reliable, high-performing user experience.
