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.

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. If you had to create a report on the successful and unsuccessful Web page hits you would not want your audience to ponder; what is the meaning of ?

You can match fields in your events to fields in external sources, such as lookup tables, and use these matches to add more information inline to your events. You can also use the results of a search to populate the CSV file or KV store collection and then set that up as a lookup table. After you configure a fields lookup, you can invoke it from the Search app with the lookup command. You have a field lookup named dnslookup which references a Python script that performs a DNS and reverse DNS lookup and accepts either a host name or IP address as arguments. You can use the lookup command to match the host name values in your events to the host name values in the lookup table, and add the corresponding IP address values to your events.

For example:. See Command types. For example, if you run a lookup search where type is both the match field and the output field, you are creating a lookup reference cycle. For more information about lookup reference cycles see Define an automatic lookup in Splunk Web in the Knowledge Manager Manual. If you are using the lookup command in the same pipeline as a transforming command , and it is possible to retain the field you will lookup on after the transforming command, do the lookup after the transforming command.

Splunk lookup table

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.
