Logstash 6.2.3 已发布，本次更新 core 没有任何变更，主要是插件方面的改变： Plugins Fluent codec Added ability to encode tags as fluent forward protocol tags Netflow codec Improved decoding performance of ASA ACL ids, MAC addresses and IPv4 addresses KV Filter Added option to split fields and values using a regex pattern (#55) Mutate Filter Introduced support for number strings using a decimal comma (e.g. 1,23), added convert support to specify integer_eu and float_eu Beats Input Improved memory management and back pressure handling JDBC Input Added fixes for thread and memory leak Syslog Input Changed syslog field to be a configurable option. This is useful for when codecs change the field containing the syslog data. Elasticsearch Output Changed sniffing behavior to connect only to http.enabled nodes that serve data for Elasticsearch 5.x and 6.x. Master-only nodes are ignored. (For Elasticsearch 1.x and 2.x, any nodes with http.enabled are added to the hosts lists, including master-only nodes.) Logstash 是一个应用程序日志、事件的传输、处理、管理和搜索的平台。你可以用它来统一对应用程序日志进行收集管理，提供 Web 接口用于查询和统计。Logstash 现在也是 ElasticSearch 家族成员之一。 发布说明：https://www.elastic.co/guide/en/logstash/6.2/logstash-6-2-3.html 下载地址：https://www.elastic.co/downloads/logstash Logstash 6.2.3 发布，开源服务端数据处理流程下载地址
