Logstash 配置 多個kafka出現InstanceAlreadyExistsException問題

[kafka_spout:7-MultipleThreadSpoutExecutors] WARN o.a.kafka.common.utils.AppInfoParser - Error registering AppInfo mbean

javax.management.InstanceAlreadyExistsException: kafka.consumer:type=app-info

閱讀源碼不難發現

問題出在配置每個kafka時需要指定唯一的client_id，有一篇裏面講到了，這裏就不重複寫了，http://www.mamicode.com/info-detail-1889211.html

貼個簡單配置：

input {

    kafka {
        type => "system"
        bootstrap_servers => "Kafka-01:19092,Kafka-02:19092,Kafka-03:19092"
        group_id => "log_admin"
        client_id => "log_system"
        topics => ["system_log"]
        auto_offset_reset = "earliest"
        consumer_threads => 3
        decorate_events => true
        codec => 'json'
    }

    kafka {
        type => "business"
        bootstrap_servers => "Kafka-01:19092,Kafka-02:19092,Kafka-03:19092"
        group_id => "log_admin"
        client_id => "log_business"
        topics => ["business_log"]
        auto_offset_reset = "earliest"
        consumer_threads => 3
        decorate_events => true
        codec => 'json'
    }	

}

output {
    if[type] == "system" {
        elasticsearch {
            hosts => ["ES-01:9200", "ES-02:9200", "ES-03:9200"]
            index => "system_log_managenment-%{+YYYY.MM.dd}"
        }
    } else if [type] == "business" {
         elasticsearch {
            hosts => ["ES-01:9200", "ES-02:9200", "ES-03:9200"]
            index => "business_log_managenment-%{+YYYY.MM.dd}"
        }
    }
    
    stdout {
        codec => rubydebug
    }
}
