Logical Health and Observability Plane

Return to L Terms

The Logical Health and Observability Plane supports logical operational awareness across the distributed Logical Node network.

Logical Health and Observability Plane interactions report or expose Logical Node state, lifecycle state, heartbeat, availability, degradation, failure, warning conditions, recovery progress, runtime metrics, and other operational observations.

The Logical Health and Observability Plane reports the condition. The Logical Control Plane coordinates action. A health observation triggers a control-plane recovery command when the Logical Architecture defines that cross-plane relationship, but the two planes remain conceptually and logically distinct.

Logical Runtime Plane supporting observation of operational condition and behavior.

Specialization of Health and Observability Plane from Part 1, Section 8.4; generalised from health-monitoring, node-status, heartbeat, and observability material in the original FX Demo Reference Architecture.

The Logical Health and Observability Plane is not the same as Evidence. Health and observability information contribute to Evidence when an evidence process captures, preserves, and traces it to a claim or review purpose.

A logical heartbeat event reports that a Logical Node remains Running. A logical degraded-status event reports that a Logical Node has entered the Degraded lifecycle state.
