prometheus-operator - 配置 prometheus-operator 以从 blackbox-operator 中抓取静态 icmp 目标

Question

我需要如何配置一个monitoring.coreos.com/v1 Probe来检测我的 prometheus-operator 以icmp从定义的目标列表中收集指标？

这假设您已经安装了 prometheus- 和 blackbox-exporter，如下所示：

helm install prometheus prometheus-community/kube-prometheus-stack -n monitoring --create-namespace
helm install prometheus-blackbox-exporter prometheus-community/prometheus-blackbox-exporter -n monitoring

首先，您需要icmp在值文件中启用 blackbox-exporter 的模块，例如blackbox-exporter.yml：

config:
  modules:
    icmp:
      prober: icmp
      icmp:
        preferred_ip_protocol: ip4

allowIcmp: true

应用配置：

helm upgrade prometheus-blackbox-exporter prometheus-community/prometheus-blackbox-exporter -f blackbox-exporter.yml

那么你可以Probe这样定义：

apiVersion: monitoring.coreos.com/v1
kind: Probe
metadata:
  name: blackbox-probe-icmp
  namespace: monitoring
  labels:
    release: prometheus
spec:
  jobName: icmp
  interval: 1m
  scrapeTimeout: 5s
  module: icmp
  prober:
    url: prometheus-blackbox-exporter:9115
  targets:
    staticConfig:
      static:
        - 192.168.1.1
        - 8.8.8.8
