Splunk has some enormously powerful features for analyzing data. One of the most popular is the ability to take highly analytical information and render it in ways that are understandable by everyone. This feature is referred to as data enrichment. The function that enables data enrichment is built into Splunk processing language and is called lookups. What are Splunk Lookups? Lookups provide the ability to substitute cryptic information with more readable information without altering the meaning.

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. Lookup table files are files that contain a lookup table. A standard lookup pulls fields out of this table and adds them to your events when corresponding fields in the table are matched in your events. All lookup types use lookup tables, but only two lookup types require that you upload a lookup table file: CSV lookups and geospatial lookups. A single lookup table file can be used by multiple lookup definitions.

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.

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.

I am new to Splunk and trying to figure out how to return a matched term from a CSV table with inputlookup. I just researched and found that inputlookup returns a Boolean response, making it impossible to return the matched term. With that being said, is the any way to search a lookup table and return a matching term? I would imagine eval would do the trick, but I have not been successful in making it work. You can match terms from input lookup on any of the above fields Field1 or Field2 as follows I am matching on Field1 and displaying Field2 :. View solution in original post. Sorry to post comment on an old answer; The solution is working fine but it uses a lot of resources when the number of rows in csv file and index size grow. In my case, I have a structured data file like this:. As there are huge number of events and quite large number of substrings in the csv file, it takes ages to return the result. Great solution!
