Logstash 1.5.0-rc3 发布，此版本主要有以下更新： Added back the ability to install plugin gems built locally on top of Logstash. This will help plugin developers iterate and test locally without having to publish plugins (#2779) Fixed performance regressions from 1.4.2 especially for configurations which have conditionals in filter and output. Throughput numbers are either inline with 1.4.2 or improved for certain configurations (#2870) Fixed issue in core which was causing Logstash to not shutdown properly (#2796) Added ability to add extra JVM options while running LS. You can use the LS_JAVA_OPTS environment variable to add to the default JVM options set out of the box. You could also completely overwrite all the default options if you wish by setting JAVA_OPTS before starting Logstash (#2942) Fixed a regression from 1.4.2 where removing a tag in filter fails if the input event isJSON formatted (#2261) Fixed issue where setting workers > 1 would trigger messages like "You are using a deprecated config setting ..." (#2865) File: When shutting down Logstash with file input, it would log a "permissions denied" message. We fixed the underlying sinceDB issue while writing to a directory with no permissions (#2964, #2935, #2882, file-input#16) Multiline: Fixed an issue where Logstash would crash while processing JSON formatted events on Java 8 (#10) Mutate: Fixed issue where you can safely delete/rename fields which can have nil values (#2977) Deprecate the usage of index_type configuration. Added document_type to be consistent with document_id (#102) Added warning when used with config embedded => true. Starting an embedded Elasticsearch node is only recommended while prototyping. This should never be used in production setting (#99) 详细信息请查看发行页面。 此版本现已提供下载： https://github.com/elastic/logstash/archive/v1.5.0-rc3.zip 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 1.5.0-rc3 发布，开源日志管理下载地址
