The following are the spec and example files for
# Version 8.1.0 #
# This file contains possible attribute and value pairs for: # * Telling Splunk how to handle multi-value fields. # * Distinguishing indexed and extracted fields. # * Improving search performance by telling the search processor how to # handle field values. # # Each stanza controls different search commands settings. # # There is a fields.conf file in the $SPLUNK_HOME/etc/system/default/ directory. # Never change or copy the configuration files in the default directory. # The files in the default directory must remain intact and in their original # location. # # To set custom configurations, create a new file with the name fields.conf in # the $SPLUNK_HOME/etc/system/local/ directory. Then add the specific settings # that you want to customize to the local configuration file. # For examples, see fields.conf.example. # You must restart the Splunk instance to enable configuration changes. # # To learn more about configuration files (including file precedence) see the # documentation located at # http://docs.splunk.com/Documentation/Splunk/latest/Admin/Aboutconfigurationfiles #
# # Use the [default] stanza to define any global settings. # * You can also define global settings outside of any stanza, at the top of # the file. # * Each conf file should have at most one default stanza. If there are # multiple default stanzas, attributes are combined. In the case of # multiple definitions of the same attribute, the last definition in the # file wins. # * If an attribute is defined at both the global level and in a specific # stanza, the value in the specific stanza takes precedence.
[<field name>|sourcetype::<sourcetype>::<wildcard expression>]
* The name of the field that you are configuring. This can be a simple field name, or it can be a wildcard expression that is scoped to a source type. * Field names can contain only "a-z", "A-Z", "0-9", "." , ":", and "_". They cannot begin with a number or "_". Field names cannot begin with a number "0-9" or an underscore "_". * Wildcard expressions have the same limitations as field names, but they can also contain and/or start with a *. * Do not create indexed fields with names that collide with names of fields that are extracted at search time. * A source-type-scoped wildcard expression causes all indexed fields that match the wildcard expression to be scoped with the specified source type. * Apply source-type-scoped wildcard expressions to all fields associated with structured data source types, such as JSON-formatted data. Do not apply it to mixed datatypes that contain both structured and unstructured data. * When you apply this method to structured data fields, searches against those fields should complete faster. * Example: '[sourcetype::splunk_resource_usage::data*]' defines all fields starting with "data" as indexed fields for 'sourcetype=splunk_resource_usage'. * The Splunk software processes source-type-scoped wildcard expressions before it processes source type aliases. * Source-type-scoped wildcard expressions require 'indexed_fields_expansion = t' in limits.conf. * Follow the stanza name with any number of the following attribute/value pairs. # 'TOKENIZER' enables you to indicate that a field value is a smaller part of a # token. For example, your raw event has a field with the value "abc123", but # you need this field to to be a multivalue field with both "abc" and "123" as # values. TOKENIZER = <regular expression> * A regular expression that indicates how the field can take on multiple values at the same time. * Use this setting to configure multivalue fields. Refer to the online documentation for multivalue fields. * If empty, the field can only take on a single value. * Otherwise, the first group is taken from each match to form the set of values. * This setting is used by the "search" and "where" commands, the summary and XML outputs of the asynchronous search API, and by the "top", "timeline", and "stats" commands. * Tokenization of indexed fields is not supported. If "INDEXED = true", the tokenizer attribute will be ignored. * No default. INDEXED = <boolean> * Indicates whether a field is indexed. * Set to "true" if the field is indexed. * Set to "false" for fields extracted at search time. This accounts for the majority of fields. * Default: false INDEXED_VALUE = [true|false|<sed-cmd>|<simple-substitution-string>] * Set to "true" if the value is in the raw text of the event. * Set to "false" if the value is not in the raw text of the event. * Setting this to "true" expands any search for "key=value" into a search for value AND key=value since value is indexed. * For advanced customization, this setting supports sed style substitution. For example, 'INDEXED_VALUE=s/foo/bar/g' takes the value of the field, replaces all instances of 'foo' with 'bar,' and uses that new value as the value to search in the index. * This setting also supports a simple substitution based on looking for the literal string '<VALUE>' (including the '<' and '>' characters). For example, 'INDEXED_VALUE=source::*<VALUE>*' takes a search for 'myfield=myvalue' and searches for 'source::*myvalue*' in the index as a single term. * For both substitution constructs, if the resulting string starts with a '[', Splunk interprets the string as a Splunk LISPY expression. For example, 'INDEXED_VALUE=[OR <VALUE> source::*<VALUE>]' turns 'myfield=myvalue' into applying the LISPY expression '[OR myvalue source::*myvalue]' (meaning it matches either 'myvalue' or 'source::*myvalue' terms). * NOTE: You only need to set 'indexed_value' if "indexed = false". * Default: true
# Version 8.1.0 # # This file contains an example fields.conf. Use this file to configure # dynamic field extractions. # # To use one or more of these configurations, copy the configuration block into # fields.conf in $SPLUNK_HOME/etc/system/local/. You must restart Splunk to # enable configurations. # # To learn more about configuration files (including precedence) please see the # documentation located at # http://docs.splunk.com/Documentation/Splunk/latest/Admin/Aboutconfigurationfiles # # These tokenizers result in the values of To, From and Cc treated as a list, # where each list element is an email address found in the raw string of data. [To] TOKENIZER = (\w[\w\.\-]*@[\w\.\-]*\w) [From] TOKENIZER = (\w[\w\.\-]*@[\w\.\-]*\w) [Cc] TOKENIZER = (\w[\w\.\-]*@[\w\.\-]*\w)
