If you are a Splunk Cloud administrator with experience creating private apps, see Manage private apps in your Splunk Cloud deployment in the Splunk Cloud Admin Manual. For example, if form=sales_order, the search looks for a sales_order.form, and matches all processed events against that form to extract values.įor Splunk Cloud Platform, you must create a private app to extract fields using form templates. The kvform command extracts field and value pairs from events based on form templates that are predefined and stored in $SPLUNK_HOME/etc/system/local/, or your own custom application directory in $SPLUNK_HOME/etc/apps/. The spath command extracts information from structured data formats, such as XML and JSON, and store the extracted values in fields.Įxtract fields from events based on form templates The xmlkv command enables you to force field and value extractions on XML-formatted tags in event data, such as transactions from web pages.Įxtract fields from XML and JSON documents The multikv command creates a new event for each table row and derives field names from the table title.Įxtract fields from events formatted in XML Use the multikv command to force field and value extractions on multiline, tabular-formatted events. You can also use the extract command to test field extractions that you add to the conf files.Įxtract fields from events formatted as tables If you use the extract command without specifying any arguments, fields are extracted using field extraction stanzas that have been added to the nf file. The extract command forces field/value extraction on the result set. If a raw event contains From: Susan To: Bob, the search extracts the field name and value pairs: from= Susan and to= Bob.įor a primer on regular expression syntax and usage, see The following are useful third-party tools for writing and testing regular expressions: In this example, values that occur after the strings From: and To: are saved into the from and to fields. The rex command matches segments of your raw events with the regular expression and saves these matched values into a field. The rex command performs field extractions using named groups in Perl regular expressions that you include in the search criteria. See About fields in the Knowledge Manager Manual. The following sections describe how to extract fields using regular expressions and commands. In Splunk Web, you can define field extractions on the Settings > Fields > Field Extractions page. The kvform command extracts field and value pairs based on predefined form templates.The xmlkv and xpath commands extract field and value pairs on XML-formatted event data.The spath command extracts field and value pairs on structured event data, such as XML and JSON.The multikv command extracts field and value pairs on multiline, tabular-formatted events.The extract (or kv, for key/value) command explicitly extracts field and value pairs using default patterns. The rex command performs field extractions using named groups in Perl regular expressions.| lookup all_identities.You can use search commands to extract fields in different ways. | lookup all_identities.csv email as EmailAddr OUTPUT userid as UserName Index="MyIndex" some search filters | spath "EmailAddr" | table EmailAddr so, now from the first search you get email id as EmailAddr, you will match it with your inputlookup csv file and then by using OUTPUT (or OUTPUTNEW), you will list down the userid as UserName. Let me assume that, your lookup all_identities.csv got two fields: userid and email. | lookup usertogroup user as local_user OUTPUT group as user_group For any entries that match, the value of the group field in the lookup table is written to the field user_group in the event. For each event, the following search checks to see if the value in the field local_user has a corresponding value in the user field in the lookup table. Your events contain a field called local_user. This lookup table contains (at least) two fields, user and group. Suppose you have a lookup table specified in a stanza named usertogroup in the nf file. Lookup users and return the corresponding group the user belongs to What should be the required-field and required-field-values values you wrote? // lets understand from the splunk documentation.ġ. The regular "lookup" is to invoke field value lookups, which is exactly your use-case. Hi I use a regular lookup instead of using inputlookup? /// Yes, the inputlookup is to "view" the contents of a lookup file.
