You can change lookup table file permissions in the. Set to true for Splunk software to verify permission settings for lookups for users. (Optional) Use the check_permission field in nf and outputlookup_check_permission in nf to restrict write access to users with the appropriate permissions when using the outputlookup command.īoth check_permission and outputlookup_check_permission default to false.If you specify a path, the Splunk software strips the path to use the value after the final path separator. The CSV file is saved in $SPLUNK_HOME/etc/system/lookups/, or in $SPLUNK_HOME/etc//lookups/ if the lookup belongs to a specific app. filename = : The name of the CSV file that the lookup references.The CSV lookup stanza names the lookup table and provides the name of the CSV file that the lookup uses. Caution: Do not edit configuration files in $SPLUNK_HOME/etc/system/default. If you want the lookup to be specific to a particular app, add its stanza to the version of nf in $SPLUNK_HOME/etc/apps//local/. If you want the lookup to be available globally, add its lookup stanza to the version of nf in $SPLUNK_HOME/etc/system/local/. $SPLUNK_HOME/etc/system/lookups $SPLUNK_HOME/etc/apps//lookups Create the lookups directory if it does not exist. The CSV file must be located in one of the following places: Add the CSV file for the lookup to your Splunk deployment.See Make your lookup automatic for information on configuring an automatic lookup.See Configure a time-based lookup for information on configuring a time-based lookup.See Handle large CSV lookup tables for information on prefiltering large CSV lookup tables.See Add field matching rules to your lookup configuration for information on field/value matching rules. See Define a CSV lookup for information on how to edit lookups.See About lookups for more information on lookups.Splunk Cloud Platform customers cannot perform this procedure. You must have access to the configuration files for your deployment.See Define roles with capabilities in Securing Splunk Enterprise. Without it you cannot manage CSV lookups in Splunk Web after you configure them. Your role must have the upload_lookup_files capability.CSV files with header rows that exceed 4096 characters.CSV files with pre-OS X (OS 9 or earlier) Macintosh-style line endings (carriage return ("\r") only).Plain ascii text is supported, as is any character set that is also valid utf-8. The CSV file cannot contain non-utf-8 characters.Any column can have multiple instances of the same value, as this represents a multivalued field. The column does not have to have the same name as the event field. One of those columns should represent a field with a set of values that includes those belonging to a field in your events. The table represented by the CSV file must have at least two columns.There are a few restrictions to the kinds of CSV files that can be used for CSV lookups: See Dataset types and usage.Įach column in a CSV table is interpreted as a potential value of a field. CSV inline lookup table files and inline lookup definitions that use CSV files are both dataset types. They are also referred to as "static lookups". Then they output corresponding field values from that table to your events. CSV lookups match field values from your events to field values in the static table represented by a CSV file.
