JMeter壓測MongoDB

1 原生方法：

vim /usr/local/jmeter/apache-jmeter-5.1.1/bin/jmeter.properties

編輯JMeter配置文件

在最后一行加入not_in_menu =

 重新啟動JMeter

在配置元件添加MongoDB Source Config (DEPRECATED)

在取樣器添加MongoDB Script (DEPRECATED)

 

 

但是此元器件存在嚴重的性能問題，

會在訪問數據庫時鎖定一個鏈接，

故在3.0以后的版本里被拋棄！

 

2 JSR223取樣器：

2.1 下載mongo-java-driver驅動

官方驅動：

https://mongodb.github.io/mongo-java-driver/

或者Maven：

https://mvnrepository.com/artifact/org.mongodb/mongo-java-driver

<!-- https://mvnrepository.com/artifact/org.mongodb/mongo-java-driver -->
<dependency>
 <groupId>org.mongodb</groupId>
 <artifactId>mongo-java-driver</artifactId>
 <version>3.8.2</version>
</dependency>

把mongo-java-driver-3.8.2.jar放到/usr/local/jmeter/apache-jmeter-5.1.1/lib/ext目錄下

rm -rf mongo-java-driver-2.11.3.jar

# 刪除/usr/local/jmeter/apache-jmeter-5.1.1/lib目錄中舊版本的mongo-java-driver jar包

 

2.2 在MongoDB中創建jmeter_test庫與blazemeter_tutorial集合

 

2.3 編寫腳本，采用JSR223 Sampler

名稱	值
mongoHost	192.168.1.111
mongoPort	27017
databaseName	jmeter_test
collectionName	blazemeter_tutorial

2.4 補充說明：

MongoClient mongoClient = MongoClients.create("mongodb://mongohost:27017");
// 不帶用戶名與密碼的鏈接方式

MongoClient mongoClient = MongoClients.create("mongodb://user:password@mongohost/?authSource=userdb&ssl=true");
// 帶用戶名與密碼的鏈接方式
