snmp_exporter加入Prometheus监控

因为不是监控交换机，所以不用编译配置文件只需要用github上打包好的release直接运行 https://github.com/prometheus/snmp_exporter

bash
scrape_configs:
  - job_name: 'ikuai_snmp'
    static_configs:
      - targets:
        - 1.2.3.4  # SNMP device.
    metrics_path: /snmp
    params:
      module: [if_mib]
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: 1.2.3.4:9116 #snmp_exporter服务器

如果需要监控交换机则需要编译mib和配置文件，需要安装go环境
