It doesn't have a value. input. This is a direct copy of what is in the autodiscover documentation, except I took out the template condition as it wouldn't take wildcards, and I want to get logs from all containers. i want to ingested containers json log data using filebeat deployed on kubernetes, i am able to ingest the logs to but i am unable to format the json logs in to fields.

This ensures you dont need to worry about state, but only define your desired configs. In this setup, I have an ubuntu host machine running Elasticsearch and Kibana as docker containers. After filebeat processes the data, the offset in the registry will be 72(first line is skipped). To get rid of the error message I see few possibilities: Make kubernetes provider aware of all events it has send to autodiscover event bus and skip sending events on "kubernetes pod update" when nothing important changes.

This works well, and achieves my aims of extracting fields, but ideally I'd like to use Elasticsearch's (more powerful) ingest pipelines instead, and live with a cleaner filebeat.yml, so I created a working ingest pipeline "filebeat-7.13.4-servarr-stdout-pipeline" like so (ignore the fact that for now, this only does the grokking): I tested the pipeline against existing documents (not ones that have had my custom processing applied, I should note).
