¿Cómo sé si el corredor Kafka se está ejecutando o no?

How do I know if Kafka broker is running or not?

I would say that another easy option to check if a Kafka server is running is to create a simple KafkaConsumer pointing to the cluste and try some action, for example, listTopics(). If kafka server is not running, you will get a TimeoutException and then you can use a try-catch sentence.

Once you install(unzip) the standalone Zookeeper,then:

1. Run the Zookeeper CLI: $ zookeeper/bin/zkCli.sh -server localhost:2181 #Make sure your Broker is already running.
2. If it is successful, you can see the Zk client running as:

Go to the Kafka home directory and execute the command ./bin/kafka-server-start.sh config/server. properties . Stop the Kafka broker through the command ./bin/kafka-server-stop.sh .

Failed to load latest commit information. The Vert.x kafka library allows asynchronous publishing and receiving of messages on Kafka topic through the vert.x event bus. ####To use this library you must have kafka and zookeeper up and running.

Kafka works well as a replacement for a more traditional message broker. Message brokers are used for a variety of reasons (to decouple processing from data producers, to buffer unprocessed messages, etc).

Since all the critical information is stored in the Zookeeper and it normally replicates this data across its ensemble, failure of Kafka broker / Zookeeper does not affect the state of the Kafka cluster. Kafka will restore the state, once the Zookeeper restarts. This gives zero downtime for Kafka.

So, at a high level, producers send messages over the network to the Kafka cluster which in turn serves them up to consumers like this: Communication between the clients and the servers is done with a simple, high-performance, language agnostic TCP protocol. We provide a Java client for Kafka, but clients are available in many languages .
