Logstash 8.5.0 Release Notes

Known issues

Due to a recent change in the Red Hat scan verification process, this version of Logstash is not available in the Red Hat Ecosystem Catalog. This bug will be fixed in the next release. Please use the Elastic docker registry to download the 8.5.0 Logstash image.

New features and enhancements

It is often difficult to understand the health of a pipeline, including whether it is exerting or propagating back-pressure or otherwise staying reasonably “caught up” with its inputs. This release adds pipeline "flow" metrics to the node_stats API for each pipeline, which includes the current and lifetime rates for five key pipeline metrics: input_throughput, filter_throughput, output_throughput, queue_backpressure, and worker_concurrency. #14518

Notable issues fixed

Added missing "monitoring.cluster_uuid" to the env2yaml list of accepted configurations and enables the user to set this configuration option via environment variable #14425
Use COPY instruction instead of ADD in Dockerfiles #14423
