Thanks Clive for the response. Custom logs can be ingested into sentinel either through single entry per line or using a timestamp matching as per the documentation. Since my logs do not follow either one of the time formats as given below, i had to use the new entry per line.
YYYY-MM-DD HH:MM:SS
M/D/YYYY HH:MM:SS AM/PM
Mon DD, YYYY HH:MM:SS
yyMMdd HH:mm:ss
ddMMyy HH:mm:ss
MMM d hh:mm:ss
dd/MMM/yyyy:HH:mm:ss zzz
yyyy-MM-ddTHH:mm:ssK
Below is the sample event that has been ingested as provided earlier in the screenshot. Any new line in the event is being considered as a new event as i had the only option to select since the time format of the custom logs ingestion method varies. All the events start with the time fields. the second event also starts with time fields but the event is spread across multiplelines. Since we have selected new line per entry the agent is picking up each and every new line as new event.
Kindly suggest if there are any other ways to ingest these logs
