MONITORING A MODEL-BASED DISTRIBUTED APPLICATION

摘要

A method for monitoring a model-based distributed application includes accessing a declarative application model describing an application intent, and deploying a model-based distributed application in accordance with the declarative application model. Events associated with the deployed application are received from a node. The received events are aggregated into node-level aggregations using a node manager. The node-level aggregations are aggregated into higher-level metrics based on the declarative application model. The higher-level metrics are stored for use in making subsequent decisions related to the behavior of the deployed application.
