概述

Prometheus监控Docker中的容器，需要借用cAdvisor，可以阅读这篇文章：docker服务监控之cAdvisor

部署cAdvisor

访问一下
http://10.0.0.10:8080/metrics

配置Prometheus

添加以下配置

scrape_configs:
  - job_name: "docker"
    scheme: "http"
    metrics_path: "/metrics"
    static_configs:
      - targets: ["10.0.0.10:8080"]
        labels:
          app: "docker"

检查语法

[root@lb ~/prometheus]# ./promtool check config prometheus.yml
Checking prometheus.yml
 SUCCESS: prometheus.yml is valid prometheus config file syntax

热加载

[root@lb ~/prometheus]# curl -X POST http://10.0.0.10:9090/-/reload

访问Prometheus检查
http://10.0.0.10:9090/targets
