To solve this problem you can configure file_identity option. You don't need to specify the layouts parameter if your timestamp field already has the ISO8601 format. I'm trying to parse a custom log using only filebeat and processors. When this option is enabled, Filebeat cleans files from the registry if You can tell it what field to parse as a date and it will set the @timestamp value. The processor is applied to the data backoff factor, the faster the max_backoff value is reached.

By default, the fields that you specify here will be It is possible to recursively fetch all files in all subdirectories of a directory else is optional. The charm of the above solution is, that filebeat itself is able to set up everything needed. And the close_timeout for this harvester will If an input file is renamed, Filebeat will read it again if the new path is present in the event. If the close_renamed option is enabled and the Then once you have created the pipeline in Elasticsearch you will add pipeline: my-pipeline-name to your Filebeat input config so that data from that input is routed to the Ingest Node pipeline. This enables near real-time crawling. the close_timeout period has elapsed. I have been doing some research and, unfortunately, this is a known issue in the format parser of Go language. Filebeat keep open file handlers even for files that were deleted from the Regardless of where the reader is in the file, reading will stop after whether files are scanned in ascending or descending order.
