Is there any way I can view the message content sent to kafka for a given topic? Say some thing like view last 5 messages for this topic, if that it possible.

Consuming from the topics in “Kafka tool”.In the tab “Properties” you can choose Key and message content type. If you added Avro plugin, as was described above you'll see Avro type as well. Choose the type used for your messages and go to the “Data” tab. Now you can see all messages that are in the selected topic.
If you want to consume only the latest message from kafka topic, Please set “Auto Offset Reset” to “LATEST” and keep other values as default. If you want to consume all the message published from kafka topic Please set “Auto Offset Reset” to “EARLIEST” and keep other values as default.
You can use console consumer to view messages produced on some topic:
bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning I work for a company with hundreds of developers who obviously need to check Kafka messages on a regular basis. Employees come and go and therefore we want to avoid the setup (dedicated SASL credentials, certificates, ACLs, ...) for each new employee.
Our platform teams operate a deployment of Kowl (https://github.com/cloudhut/kowl) so that everyone can access it without going through the usual setup. We also use it when developing locally using a docker-compose file.
