Issue/Introduction

Kafka brokers available on port 2181. However, the Kafka extension keeps reporting that it cannot find any brokers.

Log Entries:

[ERROR] [IntroscopeAgent.KafkaExtension] No Kafka brokers online to monitor
[ERROR] [IntroscopeAgent.KafkaExtension] Unexpected exception while trying to fetch Kafka brokers from zookeeper instance: APMtestKafka03.broadcom.net:2181/kafka
 [DEBUG] [IntroscopeAgent.KafkaExtension] For input string: "2181/kafka"
java.lang.NumberFormatException: For input string: "2181/kafka"

Cause

Per engineering, The log message "No Kafka brokers online to monitor" implies that zookeeper API did not fetch the connected kafka brokers. The zookeeper property expects a host:port value. So 2181/kafka is an incorrect input resulting in the exception

Environment

Release :  10.7.0

Component : APM IA, Kafka extension SaaS 20.1

Resolution

Verify that the zookeeper and brokers are correctly configured, run the following commands on the zookeeper server.

 

- ./zookeeper-shell.sh host:port

- ls /brokers/ids - This should list all the connected brokers if the config is correct.

If this works as expected, try passing the same host:port to zookeeper config property in the Kafka extension.
