Architecture

Talk and Demo

Open Source Summit NA 2022 talk and demo

Requirement

Kernel 4.18+, Cgroup V2

Installation and Configuration for Prometheus

Prerequisites

Need access to a Kubernetes cluster.

Deploy the Kepler exporter

Deploying the Kepler exporter as a daemonset to run on all nodes. The following deployment will also create a service listening on port 9102.

# kubectl create -f manifests/kubernetes/deployment.yaml 

Deploy the Prometheus operator and the whole monitoring stack

1. Clone the kube-prometheus project to your local folder.

# git clone https://github.com/prometheus-operator/kube-prometheus

2. Deploy the whole monitoring stack using the config in the manifests directory. Create the namespace and CRDs, and then wait for them to be available before creating the remaining resources

# cd kube-prometheus
# kubectl apply --server-side -f manifests/setup
# until kubectl get servicemonitors --all-namespaces ; do date; sleep 1; echo ""; done
# kubectl apply -f manifests/

Configure Prometheus to scrape Kepler-exporter endpoints.

# cd ../kepler
# kubectl create -f manifests/kubernetes/keplerExporter-serviceMonitor.yaml
