Winlogbeat 7.15.1 with sysmon missing fields task and message on Windows Server 2022

sytser · November 19, 2021, 10:44am

The issue is that on a Windows Server 2022 version with Winlogbeat v7.15.1 and Sysmon v13.24.
Some how on Windows Server 2022 Winlogbeat doesn't send the fields task and message to Logstash v7.15.2.
If we use the same config on a Windows 2019 server the fields are send.
With the Windows Security events these fields are send on Server 2022.

Is this a compatibility issue?

Could you add include_xml: true to your config and share one of the raw JSON documents sent by Winlogbeat. Is this affecting all events send on Win 2022?

Hoi Andrew,

I will do the inxclude_xml and send you the results.
At the moment alle Sysmon events are affected.

Below a raw event without the include_xml how I found out where the event fields got lost.

This is is the formatted XML from your event. It does not have a <RenderingInfo><Message> field which is where the message comes from. Can you also post the winlogbeat.yml config you're using.

Is it only Sysmon events that are affected? Do you get Security log events that contain message?

sytser · November 23, 2021, 3:55pm

It is only with Sysmon event Windows Security, System and Application event work fine and send the message field
