Ingest pipeline: how to ignore log line based on condition

[John16 (John)]

@warkolm

you can do it in filebeat though

Yes, but filebeat has no ability to parse line against regexp (to extract filter field).

Look at Exported fields in filebeat processors
which suggests to use ingest instead of filebeat

I think it would be nice (and easy) to implement an ability to ignore a line in ingest depending on some condition (after parsing a line against regexp).
