  • prometheus+grafana监控Linux和kubernetes的例子

    1.安装和配置prometheus

    tar zxvf prometheus-2.3.0.linux-amd64.tar.gz -C /usr/local/
    ln -sv /usr/local/prometheus-2.3.0.linux-amd64/ /usr/local/prometheus
    cd /usr/local/prometheus
    [root@do1cloud03 prometheus]# cat prometheus.yml |egrep -v '#'
    global:
    
    alerting:
      alertmanagers:
      - static_configs:
        - targets:
    
    rule_files:
    
    scrape_configs:
      - job_name: linux
        static_configs:
          - targets: ['192.168.1.46:9100']
            labels:
              instance: db1
      - job_name: node45
        static_configs:
          - targets: ['192.168.1.45:9100']
            labels:
              instance: node45

    /data/prometheus-2.3.0.linux-amd64/prometheus --config.file=/data/prometheus-2.3.0.linux-amd64/prometheus.yml --web.listen-address=10.253.124.27:9090

    2.安装node-exporter

    tar -zxvf node_exporter-0.16.0.linux-arm64.tar.gz
    mv node_exporter-0.16.0.linux-amd64 /usr/local/node_exporter
    ./node_exporter --web.listen-address="10.253.124.7:50002" &

    3.去官网下载node-exporter-1.6.0对应的dashboard

    https://grafana.com/grafana/dashboards

     4.去dashboard设置

     5.排错思路:在这里获取到prom sql,去Prometheus的graph查询

      对于已经存储的历史数据,Prometheus提供了PromQL语言进行查询,并自带了一个简易的UI界面,可以在界面上进行查询、绘图、查看配置、告警等等。

      需要学习简单的PromQL语言,在grafana里面根据业务自定义dashboard
