Creating search-time field extractions

The SH plays a crucial role in performing search-time extractions. When a user issues a search request, the SH executes the search and carries out search-time field extractions as part of the process.

The SH applies the defined extraction rules or patterns to the raw data during the search execution. It dynamically extracts the relevant fields and associated values from the events based on these rules. The extracted fields are then used for further analysis, filtering, visualization, or other operations.

By performing search-time extractions, the SH allows users to retrieve structured and meaningful information from the raw data without modifying the underlying data source. In addition, the following are other ways in which Splunk automatically extracts fields/values during search time without user involvement:

  • Name=value, also called key-value, pairs in raw data are auto-extracted
  • JSON structured data is auto-extracted
