makemv
Description
Converts a single valued field into a multivalue field by splitting it on a simple string delimiter, which can be a multicharacter. Alternatively, splits field by using a regex.
Syntax
makemv [delim=<string> | tokenizer=<string>] [allowempty=<bool>] [setsv=<bool>] <field>
Required arguments
- field
- Syntax: <field>
- Description: Specify the name of a field.
Optional arguments
- delim
- Syntax: delim=<string>
- Description: A string value used as a delimiter. Splits the values in
fieldon every occurrence of this string. - Default: A single space (" ").
- tokenizer
- Syntax: tokenizer=<string>
- Description: A
regex, with a capturing group, that is repeat-matched against the text of field. For each match, the first capturing group is used as a value of the newly created multivalue field.
- allowempty
- Syntax: allowempty=<bool>
- Description: Specifies whether to permit empty string values in the multivalue field. When using
delim=true, repeats of the delimiter string produce empty string values in the multivalue field. For example ifdelim=","andfield="a,,b", by default does not produce any value for the empty string. When using thetokenizerargument, zero length matches produce empty string values. By default they produce no values. - Default: false
- setsv
- Syntax: setsv=<bool>
- Description: If true, the
makemvcommand combines the decided values of the field into a single value, which is set on the same field. (The simultaneous existence of a multivalue and a single value for the same field is a problematic aspect of this flag.) - Default: false
Usage
There evaluation functions and statistical functions that you can use on multivalue fields or to return multivalue fields.
Examples
Example 1:
For sendmail search results, separate the values of "senders" into multiple values. Display the top values.
eventtype="sendmail" | makemv delim="," senders | top senders
Example 2:
Separate the value of "foo" into multiple values.
... | makemv delim=":" allowempty=true foo
