当kafka重新启动时，logstash将丢失与kafka的输入连接

我已经建立了一个elak（elasticsearch+logstash+kibana）堆栈，数据来自kafka安装。写给Kafka的主题被logstash使用，logstash最终将它们存储到elasticsearch。每个不同的产品都在docker swarm集群中的一个单独的容器中运行，只要Kafka没有失败，一切都正常。如果我重新启动kafka容器，logstash将永远失去与kafka的连接。在这种情况下，恢复logstash和kafka之间连接的唯一方法是重新启动logstash。
以下是我在Kafka重启时从logstash得到的日志：

以及Kafka关于Kafka重启后日志存储的日志：

logstash.conf中logstash的配置如下所示：

input {
  kafka {
    bootstrap_servers => "kafka:9092"
    group_id => "logstash"
    topics_pattern => ".*"
    consumer_threads => 15
    metadata_max_age_ms => "30000"
    decorate_events => true
    codec => json
  }
}

Kafka的docker服务有这样的定义：

kafka:
    image: wurstmeister/kafka:2.12-2.3.0
    depends_on:
      - zookeeper
    networks:
      - internal
    ports:
      - 9094:9094
    environment:
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
      KAFKA_GROUP_INITIAL_REBALANCE_DELAY_MS: 3000
      KAFKA_UNCLEAN_LEADER_ELECTION_ENABLE: 'true'

      KAFKA_ADVERTISED_LISTENERS: INSIDE://:9092,OUTSIDE://:8088,PLAINTEXT://:9093
      KAFKA_INTER_BROKER_LISTENER_NAME: INSIDE
      KAFKA_LOG_DIRS: /kafka/kafka-logs
      KAFKA_LOG_RETENTION_HOURS: 24
      KAFKA_DELETE_TOPIC_ENABLE: "true"
      KAFKA_NUM_PARTITIONS: 2
      JMX_PORT: 9997

有人能给我一个提示，如果可以配置logstash或Kafka在不同的方式，使logstash恢复连接Kafka自动不重新启动logstash？
提前谢谢！

我看你没有具体说明 reconnect_backoff_ms https://www.elastic.co/guide/en/logstash/current/plugins-inputs-kafka.html#plugins-输入-Kafka-重新连接\u退避\u ms我想这就是你所缺少的。
