Observability is no longer optional for modern cloud applications. While traditional monitoring shows system health, observability gives deep insight into metrics, logs, and traces, helping teams proactively troubleshoot and optimize performance. Distributed architectures, microservices, and serverless apps make observability critical. Choosing the right tools ensures your systems are reliable, scalable, and maintainable.
With observability tools, developers have to debug less and boost productivity. The DevOps teams working on microservices and distributed systems get clear insights into the system's overall working for better outputs and to provide the application system with better failure tolerance. We will delve into the top observability tools for enterprises, open-source users, and specialized scenarios.
