First you need to split the event(s) into separate lines (I have added a row count so you can keep track of the original event if that's important to you). Then extract the name/value pairs. Then create fields based on the names, with their corresponding values. Finally, join the fields together based on which line they came from.

Hi @ranjithan,

my previous answer isn't ok for your needs?

https://community.splunk.com/t5/Splunk-Search/How-to-extract-all-values/m-p/586203#M204196

the above regex extracts all the fields from your new logs.

Ciao.
