Filter and Enhance the exported data

You can define processors in your configuration to process events before they are sent to the configured output. The libbeat library provides processors for:

Each processor receives an event, applies a defined action to the event, and returns the event. If you define a list of processors, they are executed in the order they are defined in the Winlogbeat configuration file.

event -> processor 1 -> event1 -> processor 2 -> event2 ...

For example, the following filter configuration drops a few fields that are rarely used (provider_guid, process_id, thread_id, and version) and one nested field, event_data.ErrorSourceTable:

processors:
  - drop_fields:
      fields: [provider_guid, process_id, thread_id, version, event_data.ErrorSourceTable]
