Enable Serverless Metrics in Apache OpenWhisk on Kubernetes with Prometheus
summary
Shows how Apache OpenWhisk on Kubernetes emits concrete operational metrics via Kamon Prometheus exporter so Prometheus and Grafana can scrape and visualize them; demos a Helm-deployed OpenWhisk stack (controller, invoker, Kafka, CouchDB, Zookeeper) with metrics for activation latency, activation counts, memory usage and HTTP status codes exposed from controller and invoker metrics. Exporter converts Kamon meters to Prometheus format, recommends short scrapes (~7–10s), and the live demo confirms metrics appear and graphs update.
