Drop fields from events
editDrop fields from events
editThe drop_fields
processor specifies which fields to drop if a certain
condition is fulfilled. The condition is optional. If it’s missing, the
specified fields are always dropped. The @timestamp
and type
fields cannot
be dropped, even if they show up in the drop_fields
list.
Example
edit- drop_fields: when: condition fields: ["field1", "field2", ...] ignore_missing: false
If you define an empty list of fields under drop_fields
, no fields
are dropped.
Configuration settings
editElastic Agent processors execute before ingest pipelines, which means that your processor configurations cannot refer to fields that are created by ingest pipelines or Logstash. For more limitations, refer to What are some limitations of using processors?
