将proMethus`job`标签从`kubelet`更改为`kubernetes-cvisor` [英] Changing promethus `job` label from `kubelet` to `kubernetes-cadvisor`

问题描述

我正在使用Google Kubernetes引擎集群，我希望我的VerticalPodAutoscalers到use Prometheus as a history provider。 说明上写着：

将您的普罗米修斯配置为从CAdvisor获取指标。确保cAdvisor中的指标标签为JOB=kubernetes-cAdvisor。

我正在通过Helm在我的集群上安装Prometheus，使用kube-prometheus-stack图表。 似乎此图表中cadvisor指标的默认job标签为job='kubelet； 我正在查看source code for the chart，但我不知道如何操作图表值以将作业标签更改为kubernetes-cadvisor。执行此操作的正确方法是什么？

在我的普罗米修斯配置下，我能找到的唯一提及cadvisor的是：

- job_name: monitoring/prometheus-operator-kubelet/1
  honor_labels: true
  honor_timestamps: true
  scrape_interval: 30s
  scrape_timeout: 10s
  metrics_path: /metrics/cadvisor
  scheme: https
  kubernetes_sd_configs:
  - role: endpoints
    namespaces:
      names:
      - kube-system
  bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token
  tls_config:
    ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
    insecure_skip_verify: true
  relabel_configs:
  - source_labels: [__meta_kubernetes_service_label_k8s_app]
    separator: ;
    regex: kubelet
    replacement: $1
    action: keep
  - source_labels: [__meta_kubernetes_endpoint_port_name]
    separator: ;
    regex: https-metrics
    replacement: $1
    action: keep
  - source_labels: [__meta_kubernetes_endpoint_address_target_kind, __meta_kubernetes_endpoint_address_target_name]
    separator: ;
    regex: Node;(.*)
    target_label: node
    replacement: ${1}
    action: replace
  - source_labels: [__meta_kubernetes_endpoint_address_target_kind, __meta_kubernetes_endpoint_address_target_name]
    separator: ;
    regex: Pod;(.*)
    target_label: pod
    replacement: ${1}
    action: replace
  - source_labels: [__meta_kubernetes_namespace]
    separator: ;
    regex: (.*)
    target_label: namespace
    replacement: $1
    action: replace
  - source_labels: [__meta_kubernetes_service_name]
    separator: ;
    regex: (.*)
    target_label: service
    replacement: $1
    action: replace
  - source_labels: [__meta_kubernetes_pod_name]
    separator: ;
    regex: (.*)
    target_label: pod
    replacement: $1
    action: replace
  - source_labels: [__meta_kubernetes_service_name]
    separator: ;
    regex: (.*)
    target_label: job
    replacement: ${1}
    action: replace
  - source_labels: [__meta_kubernetes_service_label_k8s_app]
    separator: ;
    regex: (.+)
    target_label: job
    replacement: ${1}
    action: replace
  - separator: ;
    regex: (.*)
    target_label: endpoint
    replacement: https-metrics
    action: replace
  - source_labels: [__metrics_path__]
    separator: ;
    regex: (.*)
    target_label: metrics_path
    replacement: $1
    action: replace

推荐答案

将以下值传递给Helm：

kubelet:
  serviceMonitor:
    cAdvisor: false

# Add a scrape job for cAdvisor in accordance with the Prometheus docs
prometheus:
  prometheusSpec:
    additionalScrapeConfigs:
      - job_name: 'kubernetes-cadvisor'
        scheme: https
        metrics_path: /metrics/cadvisor
        tls_config:
          ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
        bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token
        kubernetes_sd_configs:
        - role: node
        relabel_configs:
        - action: labelmap
          regex: __meta_kubernetes_node_label_(.+)
