Logstash 6.3.1 Release Notes

edit

Adds a Persistent Queue repair utility, enabling self-recovery of corrupted PQs (Issue 9710).
Fixes two separate issues in Experimental Java Execution mode where complex pipeline configurations could fail to compile (Issue 9747, Issue 9745).
Fixes issue when running Logstash inside of a Docker container with Persistent Queue enabled where we incorrectly reported that there was insufficient space to allocate for the queue (Issue 9766).
Fixes issue in x-pack monitoring where queue_push_duration_in_millis was incorrectly reporting nanoseconds (Issue 9744).
Fixes an issue where Logstash could fail to start when its path.data is a symlink (Issue 9706).
Fixes issue with Netflow module where it could fail to populate [geoip_dst][autonomous_system] (Issue 9638).
Fixes a potential conflict with plugin depenencies that require Guava by explicitly loading Guava 22 (Issue 9592).

Plugins

edit

Netflow Codec

Fixes exception when receiving Netflow 9 from H3C devices.
Added support for Netflow 9 from H3C devices.
Fixes incorrect definitions of IE 231 and IE 232.
Fixes exceptions due to concurrent access of IPFIX templates.
Added support for Netflow 9 reduced-size encoding support.
Added support for Barracuda IPFIX Extended Uniflow.

Beats Input

Fixes an issue that prevented auto-recovery in certain failure modes.
Fixes an issue where trace-level logging omitted helpful context.

Kafka Input

Fix race-condition where shutting down a Kafka Input before it completes startup could cause Logstash to crash.
Upgrade Kafka client to version 1.1.0.

S3 Input

Avoid plugin crashes when encountering bad files in S3 buckets.
Log entry when bucket is empty.
Fixes additional_settings configuration option to properly symbolize keys for downstream library.

TCP Input

New configuration option to set TCP keep-alive.
Fixes an issue where the input could crash during shutdown, affecting pipeline reloads.

UDP Input

Mitigate memory leak in JRuby’s UDP implementation.

DNS Filter

Log timeouts as warn instead of error.
Allow concurrent queries when cache enabled.

Elasticsearch Filter

Fix: The filter now only calls filter_matched on events that actually matched. This fixes issues where all events would have success-related actions happened when no match had actually happened (add_tag, add_field, remove_tag, remove_field).

JDBC Static Filter

Fixed an issue where failing to specify index_columns would result in an obscure error message.

KV Filter

improves trim_key and trim_value to trim any sequence of matching characters from the beginning and ends of the corresponding keys and values; a previous implementation limited trim to a single character from each end, which was surprising.
fixes issue where we can fail to correctly break up a sequence that includes a partially-quoted value followed by another fully-quoted value by slightly reducing greediness of quoted-value captures.

Mutate Filter

Fix: when converting to float and float_eu, explicitly support same range of inputs as their integer counterparts.

Elasticsearch Output

Added support for customizing HTTP headers.
Log an error — not a warning — when ES raises an invalid_index_name_exception.
Improve plugin behavior when Elasticsearch is down on startup.

File Output

Fix a bug where flush interval was being called for each event when enabled

Kafka Output

Changed Kafka send errors to log as warn.
Upgrade Kafka client to version 1.1.0.

S3 Output

Fixes additional_settings configuration option to properly symbolize keys for downstream library.

SQS Output

Added the ability to send to a different account id’s queue.
