Logstash 6.0.0 introduces several significant enhancements to streamline data processing and management for system administrators and engineers. The release allows the concurrent operation of multiple pipelines within a single instance, enabling users to isolate processing logic for different data sources and reducing the need for complex conditional logic in configurations. This version also introduces centralized pipeline management through the Elastic Stack, allowing for easier orchestration and management via Kibana's UI, with configurations stored in Elasticsearch. Additionally, a new Pipeline Viewer tool in the Logstash Monitoring UI offers visualization of pipeline configurations and identifies performance bottlenecks, although it is currently in beta and may undergo changes. To facilitate the transition from Elasticsearch Ingest Nodes to Logstash for more complex use cases, a pipeline conversion tool is now available, and the upgrade to JRuby 9000 enhances compatibility with modern Ruby syntax and libraries.
