Issues with Jmeter and MongoDB: detected unknown BSON type

问题

我想要对我的 MongoDB 4.2 服务器进行 Jmeter 压力测试。
目前我没有使用任何特定的配置，我只是在本地启动 mongod 实例。

我按照这个指南设置了 jmeter：https://www.blazemeter.com/blog/mongodb-performance-testing-with-jmeter。
然而，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);
}

由于以下错误：

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

  • mongodb-driver-core.jar、mongodb-driver-sync.jar 和 bson.jar（版本分别为 4.0.3 和 3.12.3）
  • mongo-java-driver.jar 和 bson.jar（版本为 3.12.4）

你能帮我找出问题是什么吗？

英文:

I would like to stress test my MongoDB 4.2 server using Jmeter.
Right now I'm not using any particular configuration, I just start the mongod instance on localhost.

I followed this guide to set up jmeter: https://www.blazemeter.com/blog/mongodb-performance-testing-with-jmeter.
However I'm not able to correctly run the following test:

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(&quot;databaseName&quot;));
	MongoCollection&lt;Document&gt; collection = database.getCollection(vars.get(&quot;collectionName&quot;));

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

due to this error:

I tried the following MongoDB Java driver combinations (in both jmeter/lib and jmeter/lib/ext folders):

  • mongodb-driver-core.jar, mongodb-driver-sync.jar and bson.jar (both version 4.0.3 and 3.12.3)
  • mongo-java-driver.jar and bson.jar (version 3.12.4)

Can you help me figure out what's the problem?

答案1

得分: 0

我运行了一个我定制的 mongod 实例，然后我忘记了对消息格式所做的更改：因此，mongo 驱动无法与服务器通信。

所以问题出在我自己，而不是 JMeter。

英文:

I was running a mongod instance customized by me, and I forgot to stash the changes I made to the message format: Hence the mongo driver was not able to communicate with the server.

So the problem was my idiocy, not jmeter.
