## If node-exporter is deployed successfully, you can add nodes to the Prometheus host for monitoring

Add nodes to prometheus

Modify the local prometheus.yml file

//Modify the configuration file [root@prometheus ~]# tail -8 /opt/prometheus.yml 
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: "prometheus"
    static_configs:
      - targets: ["localhost:9090"]
  - job_name: "centos" //Specify a job name static_configs:
      - targets: ["192.168.237.131:9100"] //Specify the IP and port number of the node-exporter node## If there are multiple nodes - job_name: "centos"	
    static_configs:
      - targets: 
        - "192.168.237.131:9100"
        - "192.168.237.132:9100"
        - "192.168.237.133:9100"
