When Filebeat is restarted, data from the registry file is used to rebuild the state, and Filebeat continues each harvester at the last known position. filebeat: spool_size: 1024 # 最大可以攒够 1024 条数据一起发送出去 idle_timeout: "5s" # 否则每 5 秒钟也得发送一次 registry_file: ".filebeat" # 文件读取位置记录文件，会放在当前工作目录下。所以如果你换一个工作目录执行 filebeat 会导致重复传输！ See Filter and enhance the exported data for information about specifying The most permissive mask allowed is 0640.

For example, if you have a cluster of web servers, you can add the "webservers" processors in your config. Filebeat会将自己处理日志文件的进度信息写入到registry文件中，以保证filebeat在重启之后能够接着处理未处理过的数据，而无需从头开始. 如果filebeat在处理发送事件时还没有等到output的响应就意外关闭或僵死了，新发送的日志状态没有来得及记录进registry文件中，那么在filebeat重新启动后会去读取registry文件记录的信息重新发送日志，这确保了所有日志都被发送过，但可能会有重复的日志被发送 By default, the fields that you specify here will be Because they are common Filebeat is a log data shipper for local files. 1| Stop filebeat.

For the latest information, see the Filebeat is a product of Elastic.co. During the initial days of ELK (Elasticsearch, Logstash, Kibana), a single logstash jar file was used for both shipping and aggregating log events to elasticsearch. Filtering out a huge number of logs can cause many registry updates, slowing It’s Robust and Doesn’t Miss a Beat. You can The same logstash java jar file was used on all servers that needed to ship logs, and the same jar file was used to aggregate it to elasticsearch for indexing later on. The Filebeat Registry File Filebeat is designed to remember the previous reading for each log file being harvested by saving its state. You can configure the shutdown_timeout option to specify the maximum amount By default, this option is disabled, and Filebeat does not wait for the default is the number of logical CPUs available in the system.

A note on the Filebeat registry Because Filebeat is designed for sending log lines from files which are actively being written, it keeps track of the most recent log entry that it has sent to Elasticsearch, and ensures that each entry is only sent once. {beatname_uc} keeps the state of each file and persists the state to disk in the `registry_file`. Configuring Filebeat Autodiscover. filebeat.registry.flush 这个配置很特别，Filebeat 会记录文件读到了哪里，然后更新到本地文件，方便下次启动的时候继续读取文件。咋一看没有问题，但当日志量特别大的时候，registry 文件会变更特别频繁，造成非常高的磁盘 IOPS，特别是机械盘，进而影响业务程序。 The full path to the directory that contains additional input configuration files.

The effect of this method is that it will only echo the JSON for the files that do exist and will effectively remove the other files from the registry. This helps Filebeat ensure that logs are not lost if, for example, Elasticsearch or Logstash suddenly go offline (that never happens, right?
