Logstash 5.5.2 Release Notesedit

  • Optimized the response time for metrics releated APIs by caching the hostname (Issue 7857).
  • Set the JVM min and max heapsize to be 1 GB out of the box. Previously, only the max heapsize was set to 1 GB.
  • Fixed a condition where Logstash would not start when using persistent queue feature and a queue page file of zero byte existed with a fully acked checkpoint (Issue 7809).
  • Fix an issue where Logstash would crash when using the dead letter queue seek by timestamp feature.
  • Fixed an issue where Logstash would not reload unconditionally when SIGHUP was received with auto-reload turned off. (Issue 6417)
