Graylog Sidecar Winlogbeat Drop Event

f.s · March 27, 2024, 8:21am

Graylog Version: 5.2.0
Sidecar Version: 1.4.0-1

Hello,

In order to save disk space in the future, I do not want to receive certain Windows events in the graylog.
I have read that there is the possibility to specify “drop_event.when.or” in the sidecar configuration.
However, if I add this in different ways, the events are still displayed in Graylog, or the sidecar gets the status “Failed”. I have not yet been able to find a suitable solution on the Internet.

- Example of new configuration which does not work

Needed for Graylog

fields_under_root: true
fields.collector_node_id: ${sidecar.nodeName}
fields.gl2_source_collector: ${sidecar.nodeId}

output.logstash:
hosts: [“Server:Port”]
path:
data: ${sidecar.spoolDir!“C:\Program Files\Graylog\sidecar\cache\winlogbeat”}\data
tags:

windows
winlogbeat.event_logs:

ignore_older: 48h
processors:

drop_event.when.or:

- Previous configuration which works

Needed for Graylog

I have also tried with “drop_event.when.and” or with numbers in quotation marks.

I would be grateful for your help.

Greetings From Germany

I’ve never used that command, but, the config in sidecar isnt changed at all from a normal beats config, and the error messages about invalid configs come directly from beats and are just passed through sidecar.

So you may want to check the beats forums, because any answer there (for your beats version) should work.

Hello @f.s

Here’s an example of my drop events:

If you want to drop multiple event for the same channel, you need to use or because it will drop for each condition if match:

processors:
      - drop_event.when:
           or:
             - equals.winlog.event_data.fields_name: 'something'
             - regexp.winlog.event_data.fields_name: 'something'

If you want to drop only event with multiple condition, all of them need to be true to drop, also you can’t use or if you only have one condition like below

 processors:
       - drop_event.when.not:
           and:
             - equals.winlog.event_data.some_field: "something"

Notice that you can use .not condition to negate the filter

Note: my example is for winlogbeat 7.X version.
With winlogbeat 8.X versions, if you call the same channel multiple time in the conf, you need to specify a different ID:

id: security-file-system
