How to merge segmented syslog events into one?

We are currently facing the issue that we are indexing syslog data from beyond trust.

The product splits it's syslog messages if the event is bigger than 1kb.
(see docu: https://www.beyondtrust.com/docs/remote-support/how-to/integrations/syslog/message-segmentation.htm )

Example:


1st Message:
Jun 12 15:09:03 beyondtrust.instance 1 2023-06-12T15:09:03+02:00 btrs BG 22595 - [meta sequenceId="891"] 1427:01:02:site=beyondtrust.instance ;when=1686575343;who=Test User (testuser);who_ip=10.0.0.1;event=api_account_changed;old_bearer_token_long_lived=0;old_client_id=b0mm90956f58a2529gfh414681d877e3a694579b;old_client_secret=***NEW***;old_comments=;old_ecm_group=1;old_enabled=1;old_failed_login_attempts=0;old_failed_login_expiration=1680168524;old_id=3;old_ip_addresses=10.0.0.0/8,10.1.0.0/8;old_name=api-testuser;old_permissions:backup=1;new_permissions:backup=0;old_permissions:command=full_access;old_permissions:configuration=1;old_permissions:configuration_vault_account=1;old_permissions:ecm=0;old_permissions:real_time_state=0;old_permissions:reporting:archive=0;old_permissions:reporting:license=0;old_permissions:reporting:presentation=0;old_permissions:reporting:support=0;old_permissions:reportin

The only thing that indicated that an event was segmened are the "Segment Number" and the "Total Segments" fields in the header along with a field that seems to be some kind of "Message ID" - is there a way to index those two events as one by creating a custom source type? Since every event has its own timestamp this seems not possible?

Maybe there's a way to merge those two events at search-time into one since I need the whole payload to be displayed on a dashboard?

 

 

Thanks for your help! 🙂
