How to extract a field with special characters?

Hi,

I have a log statement that prints service execution time like -

Service Response : {"entity":"{\"transactionId\":\"39182d7a-7f34-4c28-a0f2-9b42b9b206df\",\"executionTimeInMillis\":112,"status":201}

I am trying to extract the value of "executionTimeInMillis".

My search statement - index="xyz" "Service Response :" | search "\"executionTimeInMillis\"\":"(?exeTime[^\$]*)," | table _time, exeTime
Note: I have added <> to exeTime. It is not showing in the question.

However, it did not show any results. Can you help me with this query?

The field extraction command is rex, not search. There may be few issues with your regex, e.g. there is no double quotes after colon. So try this

index="xyz" "Service Response :" | rex "\"executionTimeInMillis[^\:]+\:\s*(?<exeTime>[^,]+)" | table _time, exeTime
