The following are the spec and example files for
# Version 7.1.5 # # 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. # Use this file if you are creating a field at index time (not advised). # # There is a fields.conf in $SPLUNK_HOME/etc/system/default/. To set custom # configurations, place a fields.conf in $SPLUNK_HOME/etc/system/local/. For # examples, see fields.conf.example. 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
# 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.
* Name of the field you're configuring. * Follow this stanza name with any number of the following attribute/value pairs. * Field names can only contain a-z, A-Z, 0-9, and _, but cannot begin with a number or _ # TOKENIZER indicates that your configured field's value is a smaller part of a # token. For example, your field's value is "123" but it occurs as "foo123" in # your event. TOKENIZER = <regular expression> * Use this setting to configure multivalue fields (refer to the online documentation for multivalue fields). * A regular expression that indicates how the field can take on multiple values at the same time. * 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 (INDEXED = true) is not supported so this attribute is ignored for indexed fields. * Default to empty. INDEXED = [true|false] * Indicate whether a field is indexed or not. * Set to true if the field is indexed. * Set to false for fields extracted at search time (the majority of fields). * Defaults to false. INDEXED_VALUE = [true|false|<sed-cmd>|<simple-substitution-string>] * Set this to true if the value is in the raw text of the event. * Set this 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 of 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' would take the value of the field, replace all instances of 'foo' with 'bar,' and use 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>*' would take a search for 'myfield=myvalue' and search 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>]' would turn 'myfield=myvalue' into applying the LISPY expression '[OR myvalue source::*myvalue]' (meaning it matches either 'myvalue' or 'source::*myvalue' terms). * Defaults to true. * NOTE: You only need to set indexed_value if indexed = false.
# Version 7.1.5 # # 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)
