What is observability?

Observability goes beyond traditional monitoring by providing deep insight into system behavior through the collection and analysis of data like metrics, logs, events, and traces (MELT). It allows engineers to proactively identify and resolve issues in complex, modern systems—like those built with microservices and cloud-native technologies—that are difficult to predict with standard monitoring practices. Ultimately, implementing observability leads to improved system reliability, faster problem-solving, and a significant return on investment, with organizations reporting up to a 4x ROI.
