One-stop solution to your kafka visualization needs: five tools to help you work

One-stop solution to your kafka visualization needs: five tools to help you work

Abstract: Kafka is the first choice for modern distributed messaging middleware. However, For most developers, working with Kafka is not easy. In order to help developers better understand and manage Kafka clusters, many excellent Kafka visualization tools have emerged. This article will introduce five powerful and easy-to-use Kafka visualization tools and give specific code examples.

1. Kafka Manager

Kafka Manager is an open source tool developed by Yahoo, specifically used to manage Apache Kafka clusters. It provides an intuitive web interface that allows users to view the overall status of the cluster, create/consume topics, monitor consumer groups, etc. The following is a simple code example showing how to create a new topic using Kafka Manager:

// 导入相关依赖
import kafka.manager.ApiError
import kafka.manager.KafkaManager
import scala.concurrent.Await
import scala.concurrent.duration._

// 创建KafkaManager实例
val kafkaManager = KafkaManager("localhost:2181")

// 创建新主题
val createTopicResult = kafkaManager.createTopic("my_topic", partitions = 3, replicationFactor = 1)

// 检查创建结果
Await.result(createTopicResult, 10 seconds) match {
  case Right(_) => println("新主题创建成功！")
  case Left(e: ApiError) => println(s"创建主题失败：${e.getMessage}")
}

// 关闭KafkaManager实例
kafkaManager.shutdown()

2. Kafka Tool

Kafka Tool is a cross-platform Kafka visualization tool , supports Windows, Mac and Linux systems. It provides rich functions, including creating/editing topics, producing/consuming messages, viewing consumer groups, etc. The following is a simple code example showing how to use Kafka Tool to consume messages from a topic:

// 导入相关依赖
import kafka.tools.ConsoleConsumer
import kafka.utils.ZkUtils

// 创建ZkUtils实例
val zkUtils = ZkUtils("localhost:2181", sessionTimeout = 10000, connectionTimeout = 10000, isZkSecurityEnabled = false)

// 创建ConsoleConsumer实例
val consumer = new ConsoleConsumer.ConsoleConsumerConfig(zkUtils, Map[String, String](
  "bootstrap.servers" -> "localhost:9092",
  "group.id" -> "my_group"
))

// 开始消费消息
consumer.process()

// 关闭ConsoleConsumer实例
consumer.close()

// 关闭ZkUtils实例
zkUtils.close()

3. Kafka Monitor

Kafka Monitor is an open source tool developed by LinkedIn , used to monitor the health status of the Kafka cluster in real time. It provides rich dashboards and charts to display key indicators such as throughput and latency of the Kafka cluster. The following is a simple code example that shows how to use Kafka Monitor to monitor the health of a Kafka cluster:

// 导入相关依赖
import com.quantifind.kafka.monitor._

// 创建KafkaMonitor实例
val kafkaMonitor = new KafkaMonitor

// 启动监控
kafkaMonitor.run()

// 监控结果
val metrics = kafkaMonitor.getMetrics()
println(metrics)

// 停止监控
kafkaMonitor.shutdown()

4. Kafka Offset Monitor

Kafka Offset Monitor is another open source tool from LinkedIn A Kafka visualization tool for monitoring the consumption progress of Kafka consumer groups. It provides an intuitive dashboard displaying information such as topics, partitions, and consumer offsets for each consumer group. The following is a simple code example that shows how to use Kafka Offset Monitor to monitor the consumption progress of a consumer group:

// 导入相关依赖
import com.quantifind.kafka.offsetapp._

// 创建OffsetGetter实例
val offsetGetter = new OffsetGetter

// 获取消费者组的消费进度
val offsets = offsetGetter.getOffsets("my_group")

// 输出消费进度
offsets.foreach(println)

// 关闭OffsetGetter实例
offsetGetter.close()

5. Confluent Control Center

Confluent Control Center is a A commercial Kafka visualization tool developed by Confluent, specifically used to manage Confluent Platform. It provides powerful functions, including real-time monitoring, cluster management, message tracking, etc. The following is a simple code example showing how to use Confluent Control Center to create a new topic:

// 导入相关依赖
import io.confluent.controlcenter.DataPlaneClient
import io.confluent.controlcenter.CreateTopicRequest

// 创建DataPlaneClient实例
val dataPlaneClient = new DataPlaneClient("localhost:9021")

// 创建新主题
val createTopicRequest = new CreateTopicRequest("my_topic", partitions = 3, replicationFactor = 1)
val createTopicResponse = dataPlaneClient.createTopic(createTopicRequest)

// 检查创建结果
createTopicResponse.foreach(response => {
  if (response.isError()) {
    println(s"创建主题失败：${response.errorMessage()}")
  } else {
    println("新主题创建成功！")
  }
})

// 关闭DataPlaneClient实例
dataPlaneClient.close()

Conclusion: The above introduces five powerful and easy-to-use Kafka visualization tools, and gives the specific code Example. Whether through the web interface or the command line, these tools can help developers better manage and monitor Kafka clusters and improve work efficiency. Both beginners and experienced developers can benefit from it. Choosing the tools that suit you and mastering how to use them will bring great convenience to your work.
