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. They output corresponding field values from the table to your events.

One of the key features of Splunk is Lookups, which allows you to augment your data with information from external sources. Splunk Lookups are a powerful feature that allows you to enrich your data with additional information from external sources. In simple terms, Lookups allow you to add new fields to your data that are not present in the original events. These additional fields can be used to perform more advanced analysis, create reports and dashboards, and gain new insights into your data. Overall, Splunk Lookups are a powerful tool for enhancing your data analysis and gaining new insights into your data. Splunk provides several types of Lookups that you can use to enrich your data with additional information.

In this section of the Splunk tutorial you will learn the lookup tables recipes, how to use reverse lookup, using a two-tiered lookup, using multistep lookup, creating a lookup table from search results, and more.

Splunk lookup feature lets you reference fields in an external CSV file that match fields in your event data. Using this match, you can enrich your event data with additional fields. Note that we do not cover external scripted lookups or time-based lookups. These recipes extensively use three lookup search commands: lookup, inputlookup, and outputlookup. For each event, this command finds matching rows in an external CSV table and returns the other column values, enriching the events. Bydefault, matching is case-sensitive and does not support wildcards, but you can configure these options. Using the lookup command matches values in external tables explicitly. Automatic lookups, which are set up using Splunk Manager, match values implicitly.
