Elastic's release of Filebeat 7.14 introduces the filestream input, a more advanced successor to the log input, which enhances the reading of active log files by improving system reaction time, registry updates, and integration with external log rotation tools. This update significantly optimizes registry performance by adopting an append-only method for offset updates, reducing the number of fsync calls, and enabling more efficient removal of obsolete entries. Harvester management is improved, allowing parallel checking for open files needing closure, while registry operations are no longer contingent on output availability, thus expediting outdated state removal. The flexible reader pipeline now allows configurable ordering of multiline, JSON, and container log parsing, with plans for additional parsers like syslog. Enhanced cooperation with log rotation tools, particularly for copytruncate strategies, ensures correct processing of rotated files without duplicating events. Further improvements include the new include_files feature, more precise file tailing options, and a focus on continuing to refine log management capabilities based on community feedback.
