An Introduction to Microservices Monitoring—Strategies, Tools, and Key Concepts

Microservices architecture has become vital in modern application development due to its scalability, flexibility, and efficiency. However, monitoring is crucial for ensuring optimal performance and reliability of these services. Key benefits of microservices monitoring include improved end-user experience, availability, cost savings, and enhanced observability. Common metrics used for monitoring microservices include latency and response time, error rate, and resource utilization. Logs, metrics, and traces are the three types of data collected when monitoring applications. Challenges in microservices monitoring include tracking service dependencies, root cause analysis, tech stack diversity, scalability, and implementation complexity. Tools for microservices monitoring include OpenTelemetry, InfluxDB, Grafana, Telegraf, and K6. To get started with microservices monitoring, determine your monitoring strategy and requirements, select appropriate tools, and implement and integrate them into your application architecture.
