Known Issues

edit

Filebeat

  • The Filestream input does not enforce the restrictions documented for the clean_inactive option, thus allowing configurations that can lead to data re-ingestion issues.
  • When clean_inactive: 0, Filestream cleans the state of all files on start up, effectively re-ingesting all files on restart. Set clean_inactive: -1 to disable this behavior.
