             Summary: JmxReporter Fetch metrics for kafka.server should not be created when client quotas are not enabled
                 Key: KAFKA-5402
                 URL: https://issues.apache.org/jira/browse/KAFKA-5402
             Project: Kafka
          Issue Type: Bug
          Components: core
    Affects Versions: 0.10.1.1
            Reporter: Koelli Mungee
         Attachments: Fetch.jpg, Metrics.jpg

JMXReporter kafka.server Fetch metrics should not be created when client quotas are not enforced for client fetch requests. Currently, these metrics are created and this can cause OutOfMemoryException in the KafkaServer in cases where a large number of consumers are being created rapidly.

Attaching screenshots from a heapdump showing the kafka.server:type=Fetch,client-id=consumer-358567 with different client.ids from a kafkaserver where client quotas were not enabled.
