Prometheus使用node-exporter监控服务器运行情况

作用

node_exporter 是一个用于收集主机指标的 Prometheus exporter。

1.下载node-exporter

下载地址:https://github.com/prometheus/prometheus/releases

2.上传到服务器并解压

tar -zxvf xxx.tar.gz

3.启动node-exporter

#--web.listen-address=:1801注意冒号不能省略，是localhost:1801的缩写
nohup ./node_exporter --web.listen-address=:1801 >start.log &

4.访问页面查看指标

访问http://localhost:1801/metrics，能看到一堆指标，说明启动成功。

5.配置Prometheus.yml

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.

alerting:
  alertmanagers:
    - static_configs:
        - targets:

rule_files:

scrape_configs:
  - job_name: "fast-boot"
    static_configs:
      - targets: ["192.43.149.7:1888"]
        labels:
          namespace: "fast-boot"
          service: "fast-boot"
      #node-exporter的配置
      - targets: ["192.43.149.7:1801"]
        labels:
          #下面的标签可以自定义
          namespace: "fast-boot"
          service: "fast-boot"

6.配置完成后，重启prometheus

nohup ./prometheus >start.log &

如下图，说明配置成功了

7.配置grafana面板

点击dashboard，点击import，输入模板号:8919或者11074，二选一即可,个人喜欢11074。
8919模板地址:https://grafana.com/grafana/dashboards/8919-1-node-exporter-for-prometheus-dashboard-cn-0413-consulmanager/

11074模板地址:https://grafana.com/grafana/dashboards/11074-node-exporter-for-prometheus-dashboard-en-v20201010/

至此,大功告成，保存即可，细节可以自己慢慢调。
