可以发现Prometheus Endpoint已UP状态

二、部署snmp_exporter

2.1 下载安装包
1
 wget -c https://github.com/prometheus/snmp_exporter/releases/download/v0.18.0/snmp_exporter-0.18.0.linux-amd64.tar.gz
2.2 解压至 /data/tools/

[root@snmp:/root]# tar -xzf snmp_exporter-0.18.0.linux-amd64.tar.gz -C /data/tools/
[root@snmp:/root]# cd /data/tools/
[root@snmp:/data/tools]# mv snmp_exporter-0.18.0.linux-amd64/ snmp_exporter

2.3 配置snmp_exporter

snmp_exporter的配置文件需要自己通过SNMP Exporter Config Generator 项目编译生成

由于Prometheus使用go语言开发的，所以自己编译生成snmp_exporter的配置文件需要go环境

2.4 安装go并配置环境变量

cd /root
tar -xzf go1.13.3.linux-amd64.tar.gz -C /usr/local/
echo 'export PATH=$PATH:/usr/local/go/bin' >> $HOME/.profile
source $HOME/.profile
go version
2.5 go环境安装以后，构建snmp exporter config Generator
