How to extract JSON object parameters that change based on search variable?

[mannkhor]

Hi, quite a beginner here with Splunk. Is there a way to simply extract all parameters in below JSON object? The parameters returned can change based on partner.

Search: host=tp* index=pie *Avianca* OR *AFKLM* OR *British* OR *Etihad* OR *Sears* OR *IHG* OR *JETBLUE* OR *JET* OR *CARLSON* OR *EMirates* OR *Atlantic* MemberValidation RSP_JSON

  "membershipLevel": "",
  "memberId": "",
  "status": "",
  "partnerResponseMessage": "",
  "firstName": "",
  "lastName": "",
  "accountStatus": "",
  "membershipNumber": "",
  "balance": ,
  "partnerResponseCode": "",
  "email": "",
  "accountCreationDate": "",
  "stage": ""
}

Did you try setting KV_MODE=JSON in the corresponding sourcetype in props.conf?
That should actually extract fields from JSON on it's own.

To access certain fields without changing KV_MODE, take a look at | spath here:
