I have a lookup excel sheet with the application name, hostname, and IP address. I want to use it in a Splunk query and how shall I do it? You should save your excel spreadsheet as a csv comma-separated values file, making sure to follow these guidelines:. After the file is in Splunk, you should create a lookup definition. Once the lookup is properly defined, you can use these commands for interacting with it: lookup - to consult the contents of the lookup file and use fields from the lookup to enrich your event data inputlookup - to display the contents of the lookup file outputlookup - to append to the lookup file or replace its contents entirely. I suggest you go through the Search Tutorial from the beginning.

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. They are also referred to as static lookups. CSV lookups are best for small sets of data. The general workflow for creating a CSV lookup in Splunk Web is to upload a file, share the lookup table file, and then create the lookup definition from the lookup table file. CSV inline lookup table files, and inline lookup definitions that use CSV files, are both dataset types. See Dataset types and usage. See Define roles with capabilities in Securing Splunk Enterprise. After you upload the lookup file, tell the Splunk software which applications can use this file. The default app is Launcher. You must create a lookup definition from the lookup table file. Prerequisites In order to create the lookup definition, share the lookup table file so that Splunk software can see it.

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.
