prometheus 基于文件的目标发现

prometheus 基于文件的目标发现

1、创建目录

cd /usr/local/prometheus/conf
mkdir -pv targets/{nodes,docker}

2、修改prometheus.yml文件

scrape_configs:
  - job_name: 'prometheus'
    static_configs:
    - targets: ['localhost:9090']
  - job_name: 'node_exporter'
    file_sd_configs:
      - files:
        - targets/nodes/*.json
        refresh_interval: 1m
  - job_name: 'docker'
    file_sd_configs:
      - files:
        - targets/docker/*.json
        refresh_interval: 1m

3、新增targets/nodes/nodes.json文件

[{
  "targets": [
    "192.168.31.151:9100",
    "192.168.31.82:9100",
    "192.168.31.144:9100"
  ]
}]

4、新增targets/docker/docker.json文件

[{
  "targets": [
    "192.168.31.151:8080",
    "192.168.31.144:8080",
    "192.168.31.82:8080"
  ],
  "labels": {
    "datacenter":"sh"
  }
}]

5、重载

ps -ef|grep prom |grep -v grep|awk '{print $2}'|xargs kill -HUP
