Logstash 6.2.4 Release Notes

edit
  • 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

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.
