The best observability tools in 2025
What are observability tools?
Observability tools enable organizations to gain deep insights into the performance and health of their applications, infrastructure, and services. These tools collect and analyze telemetry data—like logs, metrics, and traces—to help teams monitor, troubleshoot, and optimize complex systems in real time. Observability goes beyond traditional monitoring by allowing engineers to ask ad-hoc questions about system behavior, pinpoint root causes of issues, and understand how different components interact.
