filebeat如何优化?

服务器配置
4vCore  8G内存 上面运行了java服务和filebeat
filebeat版本6.1.2

流程
filebeat -> kafka -> logstash output file (kafka , logstash 和 filebeat 在不同的机器上.)

业务繁忙时 ,日志量也比较大,用top看filebeat进程占用cpu非常的高.想问大家filebeat如何优化.
filebeat上 日志获取的频率不需要太快.


下面是之前使用的filebeat配置:

#=========================== Filebeat prospectors =============================



filebeat.prospectors:



- input_type: log

  paths:

    - /logs/wx/*.log

  fields:

    log_topic: wx

    document_type: wx

#================================ Outputs =====================================

#-----------------------------  kafka   ---------------------------------------

output.kafka:

  # initial brokers for reading cluster metadata

  hosts: ["e01:9092", "e02:9092", "e03:9092"]



  # message topic selection + partitioning

  topic: '%{[fields.log_topic]}'

  partition.round_robin:

    reachable_only: false



  version: 0.10.0.0

  required_acks: 1

  compression: none

  max_message_bytes: 1000000

下面是看过文档自己刚修改后的配置:

#=========================== Filebeat prospectors =============================



filebeat.prospectors:



- input_type: log

  paths:

    - /logs/wx/*.log

  fields:

    log_topic: wx

    document_type: wx

  scan_frequency: 60s

  backoff: 10s

#================================ General ====================================== 

  queue:

    mem:

      events: 8192

      flush.min_events: 12288

      fulsh.timeout: 60s





#================================ Outputs =====================================

#-----------------------------  kafka   ---------------------------------------

output.kafka:

  # initial brokers for reading cluster metadata

  hosts: ["e01:9092", "e02:9092", "e03:9092"]



  # message topic selection + partitioning

  topic: '%{[fields.log_topic]}'

  partition.round_robin:

    reachable_only: false



  version: 0.10.0.0

  required_acks: 1

  compression: none

  max_message_bytes: 1000000

还有那些参数可以优化吗? 另外 我这种写法不知道有没有问题, 重启filebeat的时候是没有报错的,不知道有没有生效,有什么方法能看到filebeat启动后各项参数的值吗?
