logstash Could not index event to Elasticsearch 错误原因

1、index名必须小写

  elasticsearch {
    hosts => "localhost:8607"
    index => "log2021_q4"
    document_id => "%{id}"
  }   

2、因elasticsearch配置问题导致

解决方法：

action.auto_create_index: false #禁用自动创建index

将false改成true即可，或者删除这个配置，查阅官方文档改配置是默认开启的。

多个conf文件的执行

需要配置pipeline
vi conf/pipelines.yml

- pipeline.id: log2021_q3
 pipeline.workers: 1
 pipeline.batch.size: 1
 path.config: "/usr/share/logstash/config/conf.d/log2021_q3.conf"
- pipeline.id: log2021_q4_inc
 queue.type: persisted
 path.config: "/usr/share/logstash/config/conf.d/log2021_q4_inc.conf"

执行logstash

nohup ./bin/logstash > logs/out.log &
