Splunk subsearch csv12/28/2023 ![]() When key_field is used in an outputlookup search, by default, append is set to true, which appends search results to an existing KV store collection. It is possible that the inputlookup occurs when the outputlookup is still updating some of the records. A partial update only occurs with concurrent searches, one with the outputlookup command and a search with the inputlookup command. A subsequent lookup or inputlookup search on that collection might return stale data along with new data. An outputlookup search using the key_field argument might result in a situation where the lookup table or collection is only partially updated. Default: true key_field Syntax: key_field= Description: For KV store-based lookups, uses the specified field name as the key to a value and replaces that value. Overrides the create_context argument if both arguments are used in the search. Default: false createinapp Syntax: createinapp= Description: Specifies whether the lookup table file is created in the system directory or the lookups directory for the current app context. However, if there's no file at all create_empty=false at the app level, then the lookup file in the system-level is used. If an app overrides that "test.csv" in it's own app directory with an empty file create_empty=true, the app-level lookup behaves as if the lookup is empty. There is also an app-level lookup with the same name. For example, suppose there is a system-level lookup called "test" with the lookup defined in "test.csv". If the file previously existed, the file is deleted. When set to false and there are no results, no file is created. Default: app create_empty Syntax: create_empty= Description: If set to true and there are no results, a zero-length file is created. Ignored in favor of the createinapp argument if both arguments are used in the search. Default: false create_context Syntax: create_context= app | user | system Description: Specifies where the lookup table file is created. ![]() The outputlookup command cannot append to. This means that a subsequent lookup or inputlookup search on that lookup table or collection might return stale data along with new data. An outputlookup search that is run with append=true might result in a situation where the lookup table or collection is only partially updated. csv file, the outputlookup command writes only the fields that are present in the previously existing. If append=true, the outputlookup command attempts to append search results to an existing. Fields that are not in the current search results are removed from the file. Optional arguments append Syntax: append= Description: The default setting, append=false, writes the search results to the. See Create a CSV lookup definition in the Splunk Enterprise Knowledge Manager Manual. If you associate that file with a lookup called staff, you can use either staff.csv or staff as the tablename with the outputlookup command. For example, say you have a lookup file named staff.csv. If your lookup file and the lookup definition that it is associated with have the same name, you can provide a tablename that is the same value as the corresponding filename without the. The lookup table can be configured for any lookup type (CSV, external, or KV store). tablename Syntax: Description: The name of the lookup table as specified by a stanza name in nf, which corresponds to the lookup definition. You must specify one of the following required arguments, either filename or tablename.įilename Syntax: Description: The name of the lookup file. See SPL safeguards for risky commands in Securing the Splunk Platform. ![]() As a result, this command triggers SPL safeguards. This command is considered risky because, if used incorrectly, it can pose a security risk or potentially lose data when it runs. Writes search results to a static lookup table, or KV store collection, that you specify.
