Winlogbeat drop specific system events

Elastic Stack Beats

I'm looking to collect specific System events. I would like all error and warning events. Only 36880 information events. And finally ignore older than 72 hours. This code checks out but still including information events outside 36880. Warning and Errors are still being collected as intended.

  - name: System
    ignore_older: 72h  
    processors:
     - drop_event.when.and:
        - equals.level: information
        - not.equals.event_id: 36880

Hello,

Could you please check the fields names in your data ; because depending your Winlogbeat version these fields are named differently.

Example on a 7.6 agents :
winlog.event_id
log.level

Your code then would be like this :

 - name: System
   ignore_older: 72h  
   processors:
    - drop_event.when.and:
       - equals.log.level: information
       - not.equals.winlog.event_id: 36880

Regards
