- Added dynamic config, a new feature to track config file for changes and restart the
pipeline (same process) with updated config changes. This feature can be enabled in two
ways: Passing a CLI long-form option
--auto-reloador with short-form
-r. Another option,
--reload-interval <seconds>controls how often LS should check the config files for changes. Alternatively, if you don’t start with the CLI option, you can send SIGHUP or
kill -1signal to LS to reload the config file, and restart the pipeline (Issue 4513).
- Added support to evaluate environment variables inside the Logstash config. You can also specify a
default if the variable is not defined. The syntax is
- Added ability to configure custom garbage collection log file using
bin/pluginin favor of
bin/logstash-plugin. In the next major version
bin/pluginwill be removed to prevent
PATHbeing polluted when other components of the Elastic stack are installed on the same instance (Issue 4891).
- Fixed a bug where new pipeline might break plugins by calling the
registermethod twice causing undesired behavior (Issue 4851).
LS_JAVA_OPTSwork consistently on Windows (Issue 4758).
- Fixed a bug where specifying JMX parameters in
LS_JAVA_OPTScaused Logstash not to restart properly (Issue 4319).
- Fixed a bug where upgrading plugins with Manticore threw an error and sometimes corrupted installation (Issue 4818).
- Removed milestone warning that was displayed when the
--pluginpathoption was used to load plugins (Issue 4562).
- Upgraded to JRuby 1.7.24.
- Reverted default output workers to 1. Previously we had made output workers the same as number of pipeline workers (Issue 4877).
- Enhanced to verify client certificates against CA (Issue 8).
- Breaking Change: Metadata is now disabled by default because it was regressing performance.
- Improved performance by using an internal queue and bulk ACKs.
- Increased the batch_size to 100 by default. This provides a big jump in throughput and reduction in CPU utilization (Issue 25).
- Added retry connection feature (Issue 33).
- Improved performance by adding caches to both successful and failed requests.
- Added support for retrying with the
- Lowered the default value of timeout from 2 to 0.5 seconds.
- Bumped minimum Manticore version to 0.5.4 which fixes a memory leak when sniffing is used (Issue 392).
- Fixed bug when updating documents with doc_as_upsert and scripting.
- Made error messages more verbose and easier to parse by humans.
- Retryable failures are now logged at the info level instead of warning.
