In Splunk, when an analyst is building a search and finds that extracted fields are not appearing, it often relates to the search mode being used.Smart ModeorVerbose Modeare better suited for field extraction as they allow Splunk to automatically extract and display fields based on the data being searched.

Search Modes in Splunk:

Fast Mode:Optimizes search performance by limiting field extractions to only those required by the search. If the analyst is in Fast Mode, non-required fields may not be extracted or displayed.

Smart Mode:Balances performance and field extraction, allowing fields to be automatically extracted and made available for analysis.

Verbose Mode:Extracts all fields and provides the most complete view of the data, though it may be slower.

Incorrect Options:

A. The analyst does not have the proper role to search this data:If this were the case, the analyst might not be able to search at all, rather than just missing extracted fields.

B. The analyst is searching newly indexed data that was improperly parsed:This would likely lead to no data being returned, rather than just missing fields.

C. The analyst did not add the extract command to their search pipeline:Field extraction in Splunk is usually automatic unless specific commands are used; the issue here is more likely related to search mode.
