How can i use logstash to process custom log?

Hi Mark,
Thanks for the reply. I have found the solution using Filebeat with multiline functionality.

It would be really nice if I could get one more help. I was using the Logstash S3 input plugin, but I have been struggling to implement it. I created a discuss issue but haven't got any replies. Could you please take a look at it and share your inputs.

Thanks,
