Manual field extraction

[uagraw01]

Hello Splunkers!!

I have a raw event but the fields server ip and server name are not present in this raw event. And I need to extract both these fields in Splunk during index time. Both the fields having static values. What attribute should I use in props and transform so that I can get both these files?

Servername="mobiwick"

ServerIP ="10.30.xx.56.78"

Sample raw data :

<?xml version="1.0" encoding="utf-8"?><StaLogMessage original_root="ToLogMessage"><MessageId>6cad0986-d4b2-45e2-b5b1-e6a1af3c6d40</MessageId><MessageTimeStamp>2024-11-24T07:00:00.1115119Z</MessageTimeStamp><SenderFmInstanceName>TOP/Top</SenderFmInstanceName><ReceiverFmInstanceName>BPI/Bpi</ReceiverFmInstanceName><StatisticalElement><StatisticalSubject><MainSubjectId>NICKER</MainSubjectId><SubjectId>Prodtion</SubjectId><SubjectType>PLAN</SubjectType></StatisticalSubject><StatisticalItem><StatisticalId>8</StatisticalId><Period><TimePeriodEnd>2024-11-24T07:00:00Z</TimePeriodEnd><TimePeriodStart>2024-11-24T06:00:00Z</TimePeriodStart></Period><Value>0</Value></StatisticalItem></StatisticalElement></SogMessage>

Hello @uagraw01, I believe below should work - 

props.conf - 

[<sourcetype>]
TRANSFORMS-add_fields = add_additional_field

transforms.conf - 

[add_additional_field]
REGEX = .*
FORMAT = ServerName::mobiwick ServerIP::10.30.xx.56.78
WRITE_META = true

The above will add additional 2 fields in the events. 

Note that, it will not update the _raw events.

Please accept the solution and hit Karma, if this helps!

@meetmshah  Thanks for your suggestion. I will try it definitely

Meanwhile before your suggested workaround. I have tried myself with INGEST_EVAL attribute in transforms.conf with props.conf and fields.conf and it is working.

Two things.

1) If these values are specific to particular sources, I'd add them at the source as _meta entries to an input stanza on the initial forwarder.

2) These will be indexed fields and need to be added to fields.conf. You have to remember to set INDEXED_VALUE=false for them. Otherwise Splunk will not be able to find them unless you explicitly use the fleld::value syntax.
