Prometheus 联邦【九】

 

实验拓扑图

Prometheus Server环境

192.168.40.180 xianchaomaster1 #主节点
192.168.40.181 xianchaonode1   #联邦节点1、node-exporter 
192.168.40.182 xianchaonode2   #联邦节点2、node-exporter
192.168.40.130 k8s-docker      #node-exporter


192.168.40.180监控=> 192.168.40.181、192.168.40.182

192.168.40.181监控=> 192.168.40.181 192.168.40.

192.168.40.182监控=> 192.168.40.182

部署Prometheus Server端

#xianchao1、xianchao2、xianchaomaster1、k8s-docker 四台需要部署Prometheus server和node-exproter

配置联邦Server 监控node-exporter

#Prometheus联邦节点1 192.168.40.181 
[root@xianchaonode1 apps]# cat prometheus/prometheus.yml
  - job_name: "prometheus-cluster-xianchaonode1"
    static_configs:
      - targets: ["192.168.40.181:9100"]

  - job_name: "prometheus-cluster-k8sdocker"
    static_configs:
      - targets: ["192.168.40.130:9100"]


#Prometheus联邦节点2 192.168.40.182 
[root@xianchaonode1 apps]# cat prometheus/prometheus.yml
  - job_name: "prometheus-cluster-xianchaonode2"
    static_configs:
      - targets: ["192.168.40.182:9100"]

Prometheus server采集联邦Server配置并且验证

[root@xianchaomaster1 prometheus]# cat /apps/prometheus/prometheus.yml
# my global config
global:
  scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
  alertmanagers:
    - static_configs:
        - targets:
           - 192.168.40.180:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"
  - "/apps/alertmanager/rules/rule1.yaml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: "prometheus"

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
      - targets: ["localhost:9090"]
