Help with regex needed

Hello,

I am trying to extract the system IDs from single event into the multiple events, I mean that each SID is in a separate line. I try to deploy a regex for this, without success.

Could perhaps anyone help with the below?

Kind Regards,

Kamil

By default, the rex command returns a single match.  Use the max_match option to change that.  Then use the mvexpand command to split the field into separate events.

 

| rex field=SID max_match=0 "(?<SID2>.+[^\S]+)"
| mvexpand SID2

Unfortunately this solution does not work, still getting just the first match only
