Splunk lookup table

CSV lookups are file-based lookups that match field values from your events to field values in the static table represented by a CSV file.

Lookups enrich your event data by adding field-value combinations from lookup tables. Splunk software uses lookups to match field-value combinations in your event data with field-value combinations in external lookup tables. If Splunk software finds those field-value combinations in your lookup table, Splunk software will append the corresponding field-value combinations from the table to the events in your search. You can create lookups in Splunk Web through the Settings pages for lookups. If you have Splunk Enterprise or Splunk Light and have access to the configuration files for your Splunk deployment, you can configure lookups by editing configuration files. CSV inline lookup table files and inline lookup definitions that use CSV files are both dataset types. See About datasets.
