将prometheus-operator配置为从blackbox-operator中抓取静态icmp目标

Question

如何配置monitoring.coreos.com/v1 Probe来检测我的prometheus运算符，以便从已定义的目标列表中收集icmp指标？

Answer 1

这里假设您已经按如下方式安装了prometheus导出器和blackbox导出器：

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，您需要在一个值文件中启用blackbox-exporter的icmp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

然后，您可以像这样定义Probe：

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
