Monitoring support for Knative

Knative Monitoring

This repository contains Grafana Dashboards and Prometheus Scraping configurations to monitor Knative.

It has been tested with the following configuration:

• k8s 1.19
• Istio 1.9
• kube-prometheus-stack v16.9 https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack
• knative 0.23

Also, kube-state-metrics < v2.1 doesn't export all labels by default which means you must pass the following argument to kube-state-metrics:

- --metric-labels-allowlist=pods=[*],deployments=[app.kubernetes.io/name,app.kubernetes.io/component,app.kubernetes.io/instance]

Once kube-state-metrics has been adjusted, you will need to deploy the following servicemonitors and import the dashboards in the grafana folder.

kubectl apply -f https://raw.githubusercontent.com/knative-sandbox/monitoring/main/servicemonitor.yaml
