prometheus联邦模式部署

1. 结构图如下：

2. 实验地址规划

ip	角色	主机名
192.168.25.250	prometheus主节点	prometheus-master
192.168.25.251	A机房监控汇聚	prometheus01
192.168.25.252	B机房监控汇聚	prometheus02
192.168.25.253	A机房服务器	prometheus01-01
192.168.25.197	B机房服务器	prometheus02-01

3. 部署联邦模式

3.1. 先完成服务器监控汇聚

A B 机房服务器安装node-export插件

docker run -d \
  --net="host" \
  --pid="host" \
  -v "/:/host:ro,rslave" \
  prom/node-exporter:latest \
  --path.rootfs=/host

prometheus01和prometheus01搭建：

配置文件修改：
prometheus01：
prometheus.yml:

global:
alerting:
  alertmanagers:
    - static_configs:
        - targets:
rule_files:
scrape_configs:
	# 监控自己 job的名称都需要带有prometheus后面需要匹配
  - job_name: "prometheus-01"
    static_configs:
      - targets: ["localhost:9090"]
        labels:
          app: "prometheus"
    # 监控prometheus01-01服务器
  - job_name: "prometheus-node"
    static_configs:
    - targets:
      - 192.168.25.253:9100

prometheus02：
prometheus.yml:

global:
alerting:
  alertmanagers:
    - static_configs:
        - targets:
rule_files:
scrape_configs:
	# 监控自己 job的名称都需要带有prometheus后面需要匹配
  - job_name: "prometheus-02"
    static_configs:
      - targets: ["localhost:9090"]
        labels:
          app: "prometheus"
    # 监控prometheus02-01服务器
  - job_name: "prometheus-node"
    static_configs:
    - targets:
      - 192.168.25.197:9100

两台都启动Prometheus：

docker run -d --net host  -v ./prometheus.yml:/etc/prometheus/prometheus.yml:ro prom/prometheus

确保都能监控到自己和所属节点：

3.2 prometheus主节点部署

prometheus.yml:

global:
  scrape_interval: 15s
  evaluation_interval: 15s
alerting:
  alertmanagers:
    - static_configs:
        - targets:
rule_files:
scrape_configs:
  - job_name: "prometheus"
    static_configs:
      - targets: ["localhost:9090"]
        labels:
          app: "prometheus"
  - job_name: 'prometheus-01'
    scrape_interval: 10s
    honor_labels: true
    metrics_path: '/federate'
    params:
      'match[]':
        - '{job="prometheus"}'
        - '{__name__=~"job:.*"}'
        - '{__name__=~"node.*"}'
    static_configs:
      - targets: ["192.168.25.251:9090"]

  - job_name: 'prometheus-02'
    scrape_interval: 10s
    honor_labels: true
    metrics_path: '/federate'
    params:
      'match[]':
        - '{job="prometheus"}'
        - '{__name__=~"job:.*"}'
        - '{__name__=~"node.*"}'
    static_configs:
      - targets: ["192.168.25.252:9090"]

启动：

docker run -d --net host  -v ./prometheus.yml:/etc/prometheus/prometheus.yml:ro prom/prometheus
docker run -d --name=grafana -p 3000:3000 grafana/grafana

联邦服务器已经监控上了，需要访问grafana才能看到具体监控的服务器。

添加prometheus-master数据源后，能看到prometheus02-01和prometheus01-01 服务器。
