Enable Serverless Metrics in Apache OpenWhisk on Kubernetes with Prometheus
summary
Shows how to expose OpenWhisk metrics on Kubernetes by using Kamon Prometheus exporter to convert Kamon metrics into Prometheus format, then visualizing with Prometheus + Grafana. Details which metrics are emitted—counters for activations, gauges for memory and concurrency, histograms/timers for activation latency—and where they come from (controller, invoker, Kafka, CouchDB). Includes helm deploy notes and a live demo that successfully scrapes and graphs controller and invoker metrics.
