A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

1-1Data Engineering

An engineer asks which fields Splunk extracts automatically when it indexes incoming events. Which set does the documentation name?

host, source and sourcetypeCorrect · your answerCorrect.
user, src and destCIM names such as src and dest come from search-time normalisation.
index, action and statusaction and status depend on what the data itself carries.
signature, severity and vendorThose names belong to normalised security data models.

Correct.

Concept

Fields that arrive with every event give a reviewer somewhere to start before anyone has written an extraction. They are also the cheapest thing to filter on.

Why A

Splunk documents that host, source and sourcetype values, timestamps and several other default fields are extracted automatically when events are indexed.

Source

Splunk software automatically extracts host , source , and sourcetype values, timestamps, and several other default fields when it indexes incoming events.
