Serverless (knative) Observability
We should add monitoring support for serverless via knative. We will need to do some discovery here to see what is available, but we know a few things:
- knative builds on top of Istio, which itself outputs Jaeger tracing and Prometheus metrics.
- There is support for specifying a fluentd sidecar, as well as Prometheus metrics directly from the Serving component: https://github.com/knative/serving/blob/master/config/config-observability.yaml
