Filebeat keeps the state of each file and persists the state to disk in the registry file. The file state is used to continue file reading at a previous position when Filebeat is restarted. If a large number of new files are produced every day, the registry file might grow to be too large. To reduce the size of the registry file, there are two configuration options available: clean_removed and clean_inactive.
For old files that you no longer touch and are ignored (see ignore_older), we recommended that you use clean_inactive. If old files get removed from disk, then use the clean_removed option.
