Logstash 8.15.1 Release Notes

Logstash 8.15.1 Release Notes

Known issues

  • Logstash may fail to start under some circumstances. Single and double quotes are stripped from a pipeline configuration if the configuration includes environment or keystore variable references. If this situation occurs, Logstash may fail to start or some plugins may use a malformed configuration. Check out issue #16437 for details.

    Workaround: Downgrade to Logstash 8.15.0, or temporarily avoid using environment and keystore variable references.

  • Logstash may fail to shut down under some circumstances when you are using Pipeline-to-pipeline communication. Check out issue #16657 for details.

    Workaround: Add -Dlogstash.pipelinebus.implementation=v1 to config/jvm.options. This change reverts the PipelineBus to v1, a version that does not exhibit this issue, but may impact performance in pipeline-to-pipeline scenarios.

Performance improvements and notable issues fixed

  • Fixed issue where ${VAR} incorrectly treated array as a string #16375
