Observability is the ability to understand a system's internal state by analyzing its external outputs (metrics, logs, and traces).
IT systems must be reliable, fast, efficient, and correct — Users expect high availability and strong performance at all times.
Modern distributed systems experience partial failures as the norm — In cloud and microservices environments, components fail independently and unpredictably.
Continuous visibility into software and infrastructure is essential — Teams need real-time insight into system behavior to operate confidently.
Observability provides the data to predict, detect, and respond to faults — It enables faster troubleshooting, reduces downtime, and improves resilience.
