💡 Why Policy Observability Matters
Without proper monitoring, policy systems become black boxes. You need visibility into policy performance, compliance trends, and system health to maintain effective governance at scale.
Understanding Policy Observability
Policy observability goes beyond traditional application monitoring. It encompasses tracking policy evaluation performance, compliance drift, enforcement effectiveness, and business impact. A comprehensive observability strategy provides insights into not just whether policies are working, but how well they're working and where improvements are needed.
