Hi sravankaripe,
Splunk recognize fields at search time when there is an equal (=) between field name and field value, so you can have without any activity al the fields and values.

I don't understand in your question, if you need to extract field names or field values.
If you need field names, you can use the following regex

(?<field_name>dv_[^\=]*)

if instead you want to have the values of all fields, you could use the following regex

dv_[^\=]*\=\"(?<field_name>[^\"]*)

Bye.

ex:-

dv_activity_due = value1
dv_approval = value2
dv_business_duration = value3
dv_business_service = value4
dv_business_stc = value5

Try this, where sed is used first to replace any blank values \"\" in the dv_fields with a word "Blank" and the fields are extracted thereafter:

yourQuery to return the entire string in field stringValue
| rex mode=sed field=stringValue "s/\"\"/\"Blank\"/g"
| rex field=stringValue max_match=0 "(?<dvFieldName>(dv_[^=]+))\=\"*(?<dvFieldValue>[^\"]+)"
| eval kvPair=mvzip(dvFieldName, dvFieldValue, "~")
| mvexpand kvPair
| rex field=kvPair "(?<myField>[^~]+)\~(?<myValue>[^$]+)"
| table myField, myValue

Trial example to test the above query:

| makeresults| eval stringValue="endpoint=\"https://xyz.com/\",dv_activity_due=\"UNKNOWN\",calendar_stc=\"1231961\",approval=\"not requested\",dv_urgency=\"4 - Low\",u_department=\"\",dv_u_category=\"None\",opened_by=\"frsjytyghngfchyghgmhhmhmhj\",dv_u_caused_by=\"None\",dv_u_software_model=\"\",closed_at=\"2016-11-09 21:24:09\",activity_due=\"\",dv_number=\"INC123456\",urgency=\"7\",dv_sys_created_on=\"2016-10-26 10:11:28\",service_offering=\"\",dv_service_offering=\"\",dv_upon_reject=\"Cancel all future Tasks\",parent=\"\",work_notes=\"\",parent_incident=\"\",u_territory=\"\",dv_u_area=\"None\",u_loc_code=\"\",dv_sys_tags=\"\",dv_follow_up=\"\",dv_u_node=\"\",u_caller_phone=\"(000) 000-0000\",dv_cmdb_ci=\"\",dv_u_vendor=\"IBM\",work_notes_list=\"\",priority=\"5\",upon_approval=\"proceed\",dv_notify=\"Do Not Notify\",comments=\"\",dv_approval=\"Not Yet Requested\",dv_watch_list=\"st-store0509.allmanager@kohls.com\",dv_u_loc_code=\"\",dv_business_stc=\"303,849\",sys_created_by=\"eci_mtsa\",reopen_count=\"0\",dv_sys_updated_on=\"2016-11-09 15:24:09\",dv_due_date=\"\",dv_expected_start=\"\",dv_sys_domain=\"global\",correlation_id=\"L17SRR\",impact=\"7\",dv_time_worked=\"10 Minutes\",dv_opened_by=\"MTSA Integration\",u_caused_by=\"\",u_ess_visibility=\"true\",approval_set=\"\",contract=\"\",watch_list=\"st-store0509.allmanager@kohls.com\",additional_assignee_list=\"\",dv_work_notes=\"2016-11-09 12:12:25 - MTSA Integration (Work notes)\""
| rex mode=sed field=stringValue "s/\"\"/\"Blank\"/g"
| rex field=stringValue max_match=0 "(?<dvFieldName>(dv_[^=]+))\=\"(?<dvFieldValue>[^\"]*)"
| eval kvPair=mvzip(dvFieldName, dvFieldValue, "~")
| mvexpand kvPair
| rex field=kvPair "(?<myField>[^~]+)\~(?<myValue>[^$]+)"
| table myField, myValue

Splunk should automatically extract key=value pairs in search time. Have you tried searching in Verbose mode first? (As long as KV_MODE=auto for the sourcetype)
