How to check if a Kafka process is running?

You can check if the Kafka process exists through the following methods:

1. To use the ps command: Type ps -ef | grep kafka in the terminal to view a list of processes containing the keyword “kafka.” If there is a matching process, it means the Kafka process exists.
2. To check for the presence of a Kafka process, use the jps command in the terminal. Simply type jps to view the list of Java processes, and if any of them include the keyword “kafka,” then the Kafka process is indeed running.
3. To view Kafka’s log files, you can check the two main log files- the log file of the Kafka server and the log file of Zookeeper, to see if both servers have started successfully.
4. Utilize the built-in command line tools provided by Kafka: Kafka provides various command line tools such as kafka-topics.sh and kafka-console-consumer.sh. Running these command line tools and successfully outputting results indicates the presence of the Kafka process.

Make sure to run it in the correct environment, whether it be on the right server or in the correct Kafka installation directory.
