Question

我想使用Jmeter对我的MongoDB 4.2服务器进行压力测试。现在，我没有使用任何特定的配置，我只是在localhost上启动mongod实例。

我按照本指南设置了jmeter：https://www.blazemeter.com/blog/mongodb-performance-testing-with-jmeter。但是，我无法正确运行以下测试：

import com.mongodb.client.MongoClients;
import com.mongodb.client.MongoClient;
import com.mongodb.client.MongoCollection;
import com.mongodb.client.MongoDatabase;
import static com.mongodb.client.model.Filters.*;

import org.bson.Document;
import org.bson.types.ObjectId;
import java.util.Arrays;

try{
    MongoClient mongoClient = MongoClients.create();
    MongoDatabase database = mongoClient.getDatabase(vars.get("databaseName"));
    MongoCollection<Document> collection = database.getCollection(vars.get("collectionName"));

    Document document = new Document("_id", 7);
    collection.insertOne(document);
}
catch (Exception e){
    SampleResult.setSuccessful(false);
    SampleResult.setResponseCode("500");
    SampleResult.setResponseMessage("Exception: " + e);
}

由于此错误：

我尝试了以下MongoDB Java驱动程序组合（在jmeter / lib和jmeter / lib / ext文件夹中）：

mongodb-driver-core.jar，mongodb-driver-sync.jar和bson.jar（版本4.0.3和3.12.3）
mongo-java-driver.jar和bson.jar（版本3.12.4）

您能帮我找出问题所在吗？

Answer 1

我正在运行一个由我自定义的mongod实例，但是我忘记存储对消息格式所做的更改：因此mongo驱动程序无法与服务器通信。

所以问题出在我的愚蠢而不是jmeter。
