kube-prometheus-stack выдает метрики парсинга

Question

kube-prometheus-stack выдает метрики парсинга

Общая информация о кластере:

Версия Kubernetes: 1.19.13
Используемое облако: частное
Способ установки: kubeadm init
ОС хоста: Ubuntu 20.04.1 LTS
CNI и версия: Weave Net: 2.7.0
CRI и версия: Docker: 19.3.13

Я пытаюсь получить kube-prometheus-stackдиаграмма руля для работы. Кажется, что для большинства целей это работает, однако некоторые цели остаются внизу, как показано на скриншоте ниже.

Есть ли предложения, как я могу получить kube-etcd, kube-controller-manager и kube-scheduler контролируется?

Я развернул диаграмму руля, как упоминалось здесь, и применил предложение здесь, чтобы контролировать kube-proxy с помощью Prometheus.

Заранее благодарю за любую помощь!

Это потому что Prometheus отслеживает неправильные конечные точки этих целей и / или цели не предоставляют конечную точку метрик.

Брать controller-manager Например:

Измените адрес привязки (по умолчанию: 127.0.0.1):

      $ sudo vi /etc/kubernetes/manifests/kube-controller-manager.yaml
apiVersion: v1
kind: Pod
metadata:
  ...
spec:
  containers:
  - command:
    - kube-controller-manager
    ...
    - --bind-address=<your control-plane IP or 0.0.0.0>
    ...

Если вы используете IP-адрес уровня управления, вам необходимо изменить livenessProbe и startupProbe хозяин тоже.

Изменить порт конечной точки (службы) (по умолчанию: 10252):

      $ kubectl edit service prometheus-kube-prometheus-kube-controller-manager -n kube-system
apiVersion: v1
kind: Service
...
spec:
  clusterIP: None
  ports:
  - name: http-metrics
    port: 10257
    protocol: TCP
    targetPort: 10257
 ...

Изменить схему servicemonitor (по умолчанию: http):

      $ kubectl edit servicemonitor prometheus-kube-prometheus-kube-controller-manager -n prometheus
apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
...
spec:
  endpoints:
  - bearerTokenFile: /var/run/secrets/kubernetes.io/serviceaccount/token
    port: http-metrics
    scheme: https
    tlsConfig:
      caFile: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
      insecureSkipVerify: true
  jobLabel: jobLabel
  ...

Вы можете обновить файл конфигурации Kubeadm, чтобы изменить адрес привязки.

      scheduler:
  extraArgs:
    address: 0.0.0.0
    bind-address: 0.0.0.0

...

controllerManager:
  extraArgs:
    address: 0.0.0.0
    bind-address: 0.0.0.0
