Entity Graph
Expose application state as a connected graph of entities for visualization.
Introduction
The Entity Graph is a common format for application components to expose their internal state for monitoring in the form of a graph of entities.
- Entities can be shared between components, identified by common identifiers
- Links between entities form edges in the graph.
- Properties on entities and links describe instantaneous metric values.
At runtime, any visualization frameworks can create a CollectEntityGraph directive to collect all active entities exposed by running controllers.
