简介
家里的h3c路由器是支持snmp的，所以就想着监控起来，型号是ER3200G3
找mib
首先要找mib，貌似h3c的mib都是通用的，我是从下面这个地址下载的
配置路由器
路由器这边首先开启snmp，我是v1到v3全开的，然后本地引擎ID随便输入一个比如800007DB03360102101100其他的保持默认
编译generator
首先clone项目
git clone https://github.com/prometheus/snmp_exporter.git
进入到generator工具目录
cd snmp_exporter/generator
安装依赖
apt install golang libsnmp-dev
编译
go build
创建generator.yml
下面是我的generator.yml
mmodules:
# Default IF-MIB interfaces table with ifIndex.
if_mib:
walk:
- 1.3.6.1.2.1.1.3 # 启动时间
- 1.3.6.1.2.1.31.1.1.1.6 # 入方向字节数
- 1.3.6.1.2.1.31.1.1.1.10 # 出方向字节数
- 1.3.6.1.2.1.2.2.1.8 # 端口运行状态
- 1.3.6.1.2.1.4.20.1.1 # 获取所有的接口ip
- 1.3.6.1.4.1.25506.2.6.1.1.1.1.6 # 获取单板CPU利用率
- 1.3.6.1.4.1.25506.2.6.1.1.1.1.8 # 获取单板内存利用率

h3c路由器常用mib清单在下面
https://www.h3c.com/cn/Service/Document_Software/TechnicalInfo/PorductMaintanInfo/Router/DailyMainten/MIBList/
随便选择一个清单列表，然后找到你需要的oid就好了，然后填到上面的generator.yml中
如果你不确定oid是不是可以使用，你可以安装snmpwalk，然后使用下面的命令确认下
snmpwalk -v 2c -c public 10.10.100.1 1.3.6.1.4.1.25506.8.35.9.1.2.1.2
-v 表示的是snmp的版本，-c 表示团体名，之后就是ip，最后是oid
生成snmp.yaml
把最上面的mib文件解压,然后把里面所有的单独文件都放到项目里面的mib文件夹中
生成
./generator generate -o snmp.yml
安装snmp-exporter
编写deployment
apiVersion: apps/v1
kind: Deployment

编写service
apiVersion: v1
kind: Service
metadata:
name: h3c-snmp-exporter

spec:
type: ClusterIP
selector:
app: h3c-snmp-exporter
ports:
- port: 80

然后是kustomization.yaml
resources:
- deploy.yaml
- svc.yaml
- configmap.yaml
argocd 部分
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
name: h3c-snmp-exporter

repoURL: 'https://xxxxx.xxx.xx/bboysoul/kubernetes-yaml'
targetRevision: HEAD
project: default
syncPolicy:
automated: null
配置prometheus
- job_name: 'h3c-snmp-exporter'
static_configs:
- targets:
- 10.10.100.1 # 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: h3c-snmp-exporter
添加grafana dashboard
这个就没有什么好说的了
最后吐槽两句
如果的产品过了保修期，那么你打h3c的客服，他们是不会帮助你的，你只能论坛发帖子，草
