Definition
In AI engineering, observability refers to the capability to understand the internal state of complex machine learning systems by analyzing their external outputs. It goes beyond traditional monitoring by enabling root cause analysis of unexpected behaviors in models and infrastructure. Key components include metrics, logs, and distributed tracing, which together provide visibility into model performance, latency, and data drift, ensuring reliability and facilitating debugging in production environments.
