The system generates the ACs based on component models for each component type in the network and may perform offline evaluation of the ACs using determined conditional probabilities and potential state values and cache the results. When an issue is identified at a component, the system uses a relational schema to determine a set of components on which the component depends and creates a diagnosis model for performing root cause analysis. The diagnosis model includes the component type ACs corresponding to each of the components identified in the relational schema. The system populates the diagnosis model with conditional probabilities and observed state values determined from event indications generated by the components. The system outputs a most probable explanation of the issue based on evaluation of the diagnosis model.
