JMeter Plugin to load test Apache Kafka topics/brokers

DI-KafkaMeter

Introduction

This plugin is an extended version of Kafkameter with restructured UI and additional features.

Required Components

1. Apache Jmeter
2. Kafka connection configs

Jar Dependencies Required

• kafka-clients-3.3.1
• guava-31.1-jre
• lz4-java-1.8.0
• snappy-java-1.1.8.4
• zstd-jni-1.5.2-1

Jmeter Target

• Jmeter version 5.x or above
• Java 8 or above

What's New?

• Fixed the serializer default value for producer
• Consumer Support Enhancement
• Provided support for security (Including JAAS support)
• Removed redundant libraries and built as non shaded jar.
• Ability with the consumer to define the no of records to read per request

Installation Instructions

• Download the source code from the GitHub.
• Just do a mvn clean install (M2 is required)
• Jar will be generated under the target directory (di-kafkameter-1.1.jar).
• Copy the Jar to <Jmeter Installed Directory>/lib/ext/

Config Elements

• Producer Config Element - wiki
• Consumer Config Element - wiki

Config Properties for Config Element.

Please refer the Wiki for the list of properties - which can be used

• Producer config properties - wiki
• Consumer config properties - wiki

Credits

A big thanks to the Instaclustr for providing free tier, which really helped to validate this plugin on kafka.

Kudos to the Instaclustr team to make it easier for the end user to spin up the cluster in no time.

di-kafkameter's Issues

Jmeter cannot recognize the di-kafkameter-1.2.jar

Jmeter cannot recognize the di-kafkameter-1.2.jar

Issue when Max poll record is incread.

I tried increasing max poll record. The plugin won't work in that case.

java.lang.NoSuchMethodError on running kafka consumer sampler

Hello, I'm getting this error when running the consumer sampler

java.lang.NoSuchMethodError: org.apache.kafka.clients.consumer.KafkaConsumer.poll(Ljava/time/Duration;)Lorg/apache/kafka/clients/consumer/ConsumerRecords;

The Config I'm using is

and the sampler configuration is

I'm using di-kafkameter-1.2.jar
and the jmeter version is 5.5
any insight on this error?

Thank you

Consumer Sampler

Needs to Add a feature to have consumer sampler to read events/messages from Kafka Topic

Response code:500 cannot send message to the local Kafka broker

I have installed docker-compose based local server on Mac

Conflicts with plugin rollno748/Jmeter-pubsub-sampler

I am currently using rollno748/Jmeter-pubsub-sampler to send requests to Pub/Sub and this works well. However, If i have both plugins - rollno748/Jmeter-pubsub-sampler and rollno748/di-kafkameter installed, and I run the same pub/sub test plan, JMeter throws the following stacktrace:

Needs to come up with a clear documentation on using this sampler with JMeter

Kafka Produce Config could not replicate distributed messages

Hi is there a configuration that allows to configure such that the messages are send in distributed manner? Because when i did a load test, the messages will only send to one partition.

For example, i had a topic called 'test-topic' and 3 partition, when i run the jmeter, it will randomly choose one partition, and send all the message to the partition, instead of evenly distributed.

Illustration:
Topic: test-topic
Amount of message to send: 5 message

Current scenario:
partition-0: 5
partition-1: 0
partition-2 : 0

Desired output (more distributed):
partition-0:1
partition-1:2
partition-3: 2

Here is my config:

Queue for multi-thread consumers. How to organize consumers for multi-thread access?

Hello!
Assume that we have 1 pool of values for multiple threads and we want to get fresh value every time we ask for it.
Example of it is VTS which I used with LoadRunner. HTTP Simple Table Server has the same idea.
When I launch 2 threads I get exception: KafkaConsumer is not safe for multi-threaded access.
How should I configure consumers to get fresh values with multiple threads and is it possible?

Only String Serializer Values are allowed

The thing is that we need to modify the “Kafka Producer Serializer value” because for some specific message we have a different serializer, but the only value that works is “org.apache.kafka.common.serialization.StringSerializer”. I would need to use the value “org.apache.kafka.common.serialization.Serializer” or “com.tomtomwork.webfleet.components.binaryprotocol.kafka.serialization.ProtocolBlockSerializer”, but when doing so and try to send the message, there is an error

See examples of different serializers value below:

• 
• 

See the error when sending the kafka sampler below:

In the code plugin (https://github.com/rollno748/di-kafkameter/blob/master/src/main/java/com/di/jmeter/kafka/config/KafkaProducerConfig.java#L97-L98), it seems the interface allowed is only java.io.Serialize, but I would need to be able other serializers which use/implements “org.apache.kafka.common.serialization.Serializer” instead of “org.apache.kafka.common.serialization.StringSerializer”. It seems the plugin only allows string serializer (See he error message => Can't convert value of class java.lang.String to class org.apache.kafka.common.serialization.ByteArraySerializer specified in value.serializer)

So, oher Serializer Values such as the ones below should be able to be used:

• org.apache.kafka.common.serialization.ByteArraySerializer
• org.apache.kafka.common.serialization.ByteBufferSerializer
• com.tomtomwork.webfleet.components.binaryprotocol.kafka.serialization.ProtocolBlockSerializer (Specific implementation)

Is there any way to add support for other serializers into the di-kafkaplugin?

New consumer feature not well documented

https://github.com/rollno748/di-kafkameter/wiki#consumer-elements
still references producer in the consumer section.

Problems running more than one consumer

I have a simple setup trying to run a kafka consumer. I tried to follow the wiki for the consumer but it's not well documented. Please see #9. The wiki mentions that the Variable Name should be unique. I'm trying to generate a unique one per thread. Everything works fine with 1 thread but scaling to more than on thread raises the following error

Not able to add jmeter variables in producer messages

I am trying to producer dynamic messges, but the jmeter variables are not substituted in the messages, any reason why?
