【夜莺监控方案】09-监控服务主机存活和服务端口(ICMP/TCP/HTTP)（prometheuse+n9e+blackbox_exporter）

文章目录

• 1. 安装 blackbox_exporter
• 2. 配置prometheus
• • 2.1 主机存活（ICMP）
  • 2.2 TCP端口状态
  • 2.3 HTTP端口状态
  • 2.4 重启 prometheus
• 3. 配置n9e图表
• • 3.1 手动配置（方法一）
  • 3.2 导入模板（方法二）

1. 安装 blackbox_exporter

• 创建 /opt/ blackbox_exporter目录
• 在/opt/ blackbox_exporter目录下创建docker-compose.yml文件如下：

version: '3.3'
services:
  blackbox_exporter:
    image: bitnami/blackbox-exporter
    container_name: blackbox_exporter
    #network_mode: "host"
    ports:
      - 9115:9115
    restart: always

• 启动服务

docker-compose up -d

• 查看启动结果

      Name                     Command               State   Ports
------------------------------------------------------------------
blackbox_exporter   /opt/bitnami/blackbox-expo ...   Up     0.0.0.0:9115->9115/tcp

• 验证
  访问 http://IP:9115 看到数据说明启动成功

2. 配置prometheus

• 配置prometheus.yml，添加项目如下：

2.1 主机存活（ICMP）

2.4 重启 prometheus

3. 配置n9e图表

3.1 手动配置（方法一）

参考《04-监控redis集群-prometheuse+n9e》中“3.2 配置图表"

指标可以访问 http://IP:9115自己找

3.2 导入模板（方法二）

我写的模板内容如下：

[
  {
    "id": 0,
    "name": "端口和主机存活",
    "tags": "",
    "configs": "{\"tags\":[{\"tagName\":\"job\",\"key\":\"job\",\"value\":\"*\",\"prefix\":false,\"metric\":\"probe_success\"},{\"tagName\":\"project\",\"key\":\"project\",\"value\":\"HQ-AllInOne-PC\",\"prefix\":false,\"metric\":\"probe_success\"}]}",
    "chart_groups": [
      {
        "id": 0,
        "dashboard_id": 0,
        "name": "Default chart group",
        "weight": 0,
        "charts": [
          {
            "id": 538,
            "group_id": 156,
            "configs": "{\"name\":\"端口是否存活\",\"mode\":\"nightingale\",\"metric\":[\"probe_success\"],\"tags\":{\"group\":[\"http\",\"tcp\"]},\"layout\":{\"h\":2,\"w\":24,\"x\":0,\"y\":0,\"i\":\"0\"}}",
            "weight": 0
          },
          {
            "id": 539,
            "group_id": 156,
            "configs": "{\"name\":\"嗅探花费时间（秒）\",\"mode\":\"nightingale\",\"metric\":[\"probe_dns_lookup_time_seconds\"],\"tags\":{},\"layout\":{\"h\":2,\"w\":24,\"x\":0,\"y\":4,\"i\":\"1\"}}",
            "weight": 0
          },
          {
            "id": 540,
            "group_id": 156,
            "configs": "{\"name\":\"主机存活\",\"mode\":\"nightingale\",\"metric\":[\"probe_success\"],\"tags\":{\"group\":[\"node\"]},\"layout\":{\"h\":2,\"w\":24,\"x\":0,\"y\":2,\"i\":\"2\"}}",
            "weight": 0
          }
        ]
      }
    ]
  }
]
