This documentation contains work-in-progress information for future Elastic Stack and Cloud releases. Use the version selector to view supported release docs. It also contains some Elastic Cloud serverless information. Check out our serverless docs for more details.
Here are the breaking changes for 6.0.
If you are upgrading from Logstash 6.2.x or any earlier version (including 5.x) and have the persistent queue enabled, we strongly recommend that you drain or delete the persistent queue before you upgrade. See Draining the queue for information and instructions.
These changes can affect any instance of Logstash that uses impacted features. Changes to Logstash Core are plugin agnostic.
-
The setting
config.reload.intervalhas been changed to use time value strings such as5m,10setc. Previously, users had to convert this to a millisecond time value themselves. Note that the unit qualifier (s) is required.
-
For
rpmanddebrelease artifacts, config files that match the*.confglob pattern must be in the conf.d folder, or the files will not be loaded.
-
The
-eand-fCLI options are now mutually exclusive. This also applies to the corresponding long form optionsconfig.stringandpath.config. This means any configurations provided via-ewill no longer be appended to the configurations provided via-f. -
Configurations provided with
-forconfig.pathwill not be appended withstdininput andstdoutoutput automatically.
