# Node simulator manual

* image & chart放置位置
  * image放置在harbor上datahub-dev/Repositories/datahub-performer (Figure 1) 
  * helm chart放置在habor上datahub-dev/Helm Charts/datahub-performer (Figure 2)

![Figure 1](/files/-MCzVzo6SWTAXMIdEdUT)

![Figure 2](/files/-MCzVXBhBehMtrOnENFU)

* 使用helm chart部屬simulator

  * 到habor上複製datahub-performer values的內容
  * Figure 2圖中datahub-performer點進去到Figure 3畫面
  * 點選1.0.0到Figure 4畫面
  * 點選上方的values 複製下方的內容並存成values.yaml

![Figure 3](/files/-MCzXXOsDb-N-EOfhiQk)

![Figure 4](/files/-MCzZ52hdoQ_FR4aYEk4)

* 在values.yaml的根目錄下，執行以下指令
  * 指令說明helm install \[欲部屬的名稱] \[放置chart的資料夾名稱/chart的名稱] --version \[chart的版本號] -f ./values.yaml

```
 helm install simulator-test datahub-dev/datahub-performer --version 1.0.0 -f ./values.yaml
```

* 部屬完成後，kubectl get pod可以看到如Figure 5所示

![Figure 5](/files/-MCzacbyAnnDzhogzYHZ)

* 連進此pod進行壓測的參數設定，連進去的指令如下

```
kubectl exec -it simulator-test-datahub-performer-544d458df5-2kqfj /bin/bash
```

* 進去後執行ls指令，可以看到根目錄下的目錄結構

```
ls
```

![Figure 6](/files/-MCzbftxCEz92AugqNc_)

* 接著對setting.json進行配置，利用setting.sh用指令的方式幫你修改setting.json的內容，setting.sh的指令參數如下

```
//以下參數對應setting.json中的參數
host="" //對應mqttHost
port=1883 //對應mqttPort
username="" //對應mqttUserName
password="" //對應mqttPassword
scadaNums=1 //對應scadaNumbers
deviceNums=1 //對應deviceNumbers
tagNums=75 //對應tagNumbers
timeInterval=1000 //對應publishIntervalTime
execTime=86400 //對應exectionTime，若為0則不停止
useSame=false //對應isUseSame
```

* 指令格式: ./setting.sh paramName1=value1 paramName2=value2 paramName3=value3 ...\
  \*可以任選上面的參數填入想修改的值，(意思是可以全部都填，也可以選擇想改的參數填入就好)，以下兩種範例都舉例

```
./setting.sh host="rabbitmq-001-pub.sa.wise-paas.com" port=1883 username="03bdd820-4d47-40a2-9aff-85613c201b58:61734256-adfet-477f-9b3f-fswerwerad" password="aqetdfhwehqwthlqw" scadaNums=100 deviceNums=1 tagNums=1000 timeInterval=1000 useSame=false
```

```
./setting.sh host="rabbitmq-001-pub.sa.wise-paas.com" scadaNums=100 deviceNums=10
```

* 執行完畢後會顯示修改的內容，如下圖(Figure 7)

![Figure 7](/files/-MCzc8PJcP4WjpZnl1P8)

* 若修改正確執行node index.js啟動模擬，若修改不正確回上一步重新執行修改

```
node index.js //執行模擬
```
