A new benchmarking tool for Logstash has been introduced, inspired by Rally's success with Elasticsearch, and it offers enhanced functionality by utilizing monitoring APIs built into Logstash since version 5.x. This tool requires only a JVM and can run benchmarks on predefined configurations and data sets, such as Apache, across various Logstash distribution versions or directly from GitHub sources. The output includes performance metrics like throughput and CPU usage, and results can be shipped directly to Elasticsearch for further analysis. Planned improvements include support for custom configurations and datasets, along with detailed documentation. In addition to the benchmarking tool, several fixes and performance improvements have been made in the Logstash core and plugins, including bug fixes in the Dead Letter Queue input, enhancements in metrics calculation, and optimizations in throughput when using in-memory queues.
