ERR无法执行任何批量索引操作：filebeat到elasticsearch

Question

通过curl发送数据时我可以成功发送（从filebeat直接发送到aws elasticsearch）但是当我尝试用filebeat做类似的事情时我得到了这个错误：

2018/04/11 11:25:50.252835 reader.go:138: DBG  End of file reached: /var/log/Xorg.0.log; Backoff now.

我的Filebeat.yml是：

filebeat:
  prospectors:
    - 
      paths: 
        - /var/log/*.log
      enabled: false
output:
    elasticsearch:
      hosts: ["myelasticsearchip"]
      pipeline: test-pipeline

有人可以帮忙吗？ 在此先感谢
