Logstash 6.2.4 已发布，带来了大量修复和改进： Fixed an issue where events passing through the persistent queue had the contents of string type fields corrupted for values containing non-ASCII characters. The solution involved serializing the RubyString as Java String UTF-16 encoded #9167 Fixed serialization bug when a RubyString that comes out of a matching, substring or similar operation may not have offset 0 pointing at the underlying BytesList. Solved by serializing the correct part of the BytesList #9308 Improved performance of Event#cancel, where each operation would unnecessarily generate a new object. In configurations that use plugins like the drop filter throughput may increase up to 5x #9284 Fixed an issue with type handling in metadata fields. Before this a plugin could trigger a Java exception when placing data into an event’s metadata #9299 Fixed a race condition in shutdown of pipelines where not all workers would consume a single SHUTDOWN signal #9285 Multiple documentation improvements relating to configuration files, JVM options, default plugin codecs, Logstash-to-Logstash communication and Keystore. Plugins Json_lines Codec Support flush method, see https://github.com/logstash-plugins/logstash-codec-json_lines/pull/35 Netflow Codec Workaround for breaking change in Netflow-Input-UDP > 3.2.0, see issue #122 Renamed some unknown VMware VDS fields Aggregate Filter new feature: add timeout_timestamp_field option. When set, this option computes timeout based on event timestamp field (and not system time). It’s particularly useful when processing old logs. new feature: add inactivity_timeout option. Events for a given task_id will be aggregated for as long as they keep arriving within the defined inactivity_timeout option - the inactivity timeout is reset each time a new event happens. On the contrary, timeout is never reset and happens after timeout seconds since aggregation map creation. Dns Filter Logging improvement to include DNS resolution failure reason #36 Fix bug where forward lookups would not cache timeout errors Jdbc_streaming Filter Load the driver with the system class loader. Fixes issue loading some JDBC drivers in Logstash 6.2+ #263 Kv Filter Correctly handle empty values between value separator and field separator #58 Ruby Filter Fix return of multiple events when using file based scripts #41 Translate Filter Add refresh_behaviour to either merge or replace during a refresh #57 Beats Input Ensure that the keep-alive is sent for ALL pending batches when the pipeline is blocked, not only the batches attempting to write to the queue. #310 Exec Input Add metadata data to the event wrt execution duration and exit status Add schedule option to schedule the command to run, using a cron expression Http Input Make sure default codec is also cloned for thread safety. #80 Always flush codec after each request and codec decoding. #81 Jdbc Input Clarify use of use_column_value. Make last_run_metadata_path reference in record_last_run entry clickable. #273 Load the driver with the system class loader. Fixes issue loading some JDBC drivers in Logstash 6.2+ #263 Fix regression with 4.3.5 that can result in NULL :sql_last_value depending on timestamp format #274 Redis Input Add support for SSL #61 Add support for Redis unix sockets #64 S3 Input Improve error handling when listing/downloading from S3 #144 Add documentation for endpoint, role_arn and role_session_name #142 Add support for additional_settings option #141 Sqs Input Add documentation for endpoint, role_arn and role_session_name #46 Fix sample IAM policy to match to match the documentation #32 Tcp Input Restore SSLSUBJECT field when ssl_verify is enabled. #115 Update Netty/tc-native versions to match those in beats input #113 Udp Input Add metrics support for events, operations, connections and errors produced during execution. #34 Fix support for IPv6 #31 Aws Mixin Drop strict value validation for region option #36 Add endpoint option to customize the endpoint uri #32 Allow user to provide a role to assume #27 Update aws-sdk dependency to ~> 2 Elasticsearch Output Set number_of_shards to 1 and document_type to _doc for es 7.x clusters #741 #747 Fix usage of upsert and script when update action is interpolated #239 Add metrics to track bulk level and document level responses #585 File Output Add feature write_behavior to the documentation #58 S3 Output Add documentation for endpoint, role_arn and role_session_name #174 Add option for additional settings #173 Add more S3 bucket ACLs #158 Handle file not found exception on S3 upload #144 Document prefix interpolation #154 Sqs Output Add documentation for endpoint, role_arn and role_session_name #29 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-6-2-4.html 下载地址：https://www.elastic.co/downloads/logstash Logstash 6.2.4 发布，开源服务端数据处理流程下载地址
