Hello,
Can anyone please help me with the line breaking. Multiple Security events are merged into a single event, putting a highlight on the the timestamp where the event should break.
Event below should be split into 2.

Additional question
once we got the correct settings to props.conf and running search again will the data be the same?
or it will only work for the new events that will be ingested to splunk?
