Scrape selective kube state metrics

This document describes how to scrape selective kube state metrics

Obtain the list of kube state metrics from your Last9 cluster​

curl -XGET 'https://<username>:<password>@read-app-tsdb.last9.io/hot/v1/metrics/<token>/sender/<org_slug>/api/v1/label/__name__/values' | jq | grep -e "kube_"

Let’s decide to omit kube_certificatesigningrequest_* metrics​

  1. Prepare a list of metrics you want to omit. This needs to be a comma separated array of strings.

    [
      "kube_certificatesigningrequest_annotations",
      "kube_certificatesigningrequest_cert_length",
      "kube_certificatesigningrequest_condition",
      "kube_certificatesigningrequest_created",
      "kube_certificatesigningrequest_labels"
    ]

  2. Find the metricDenylist configuration in your Kube State Metrics Helm chart and append this list to that config.

    metricDenylist: ["kube_certificatesigningrequest_annotations", "kube_certificatesigningrequest_cert_length", "kube_certificatesigningrequest_condition", "kube_certificatesigningrequest_created", "kube_certificatesigningrequest_labels"]

  3. Now deploy your Kube State Metrics Helm chart as usual

  4. Run the below command after the deployment to verify that it is in effect. You should not find any metrics with kube_certificatesigningrequest prefix being emitted anymore

curl -XGET 'https://<username>:<password>@read-app-tsdb.last9.io/hot/v1/metrics/<token>/sender/<org_slug>/api/v1/label/__name__/values' | jq | grep -e "kube_certificatesigningrequest_"
