Chapter Chapter 13 in Heron Streaming, 2021, pp 197-205 from Springer

Abstract: Abstract HealthManager and API server were introduced to Heron recently. HealthManager is based on Dhalion, which targets self-tuning, self-stabilizing, and self-healing. It first fetches the metrics from MetricsCache Manager, next identifies the abnormalities, then diagnoses the cause, and finally tries to resolve them. The API server is the service mode for Heron scheduler. It runs inside the cloud, and Heron CLI delegates the command to the API server. We will emulate a cloud environment with Minikube and see how the API server works.
