Concatenates string values from 2 or more fields. Combines together string values and literals into a new field. A destination field name is specified at the end of the strcat command.


strcat [allrequired=<bool>] <source-fields> <dest-field>

Required arguments

Syntax: <string>
Description: A destination field to save the concatenated string values in, as defined by the <source-fields> argument. The destination field is always at the end of the series of source fields.
Syntax: (<field> | <quoted-str>)...
Description: Specify the field names and literal string values that you want to concatenate. Literal values must be enclosed in quotation marks.
Syntax: "<string>"
Description: Quoted string literals.
Examples: "/" or ":"

Optional arguments

Syntax: allrequired=<bool>
Description: Specifies whether or not all source fields need to exist in each event before values are written to the destination field. If allrequired=f, the destination field is always written and source fields that do not exist are treated as empty strings. If allrequired=t, the values are written to destination field only if all source fields exist.
Default: false


The strcat command is a distributable streaming command. See Command types.


Example 1:

Add a field called comboIP, which combines the source and destination IP addresses. Separate the addresses with a forward slash character.

... | strcat sourceIP "/" destIP comboIP

Example 2:

Add a field called comboIP, which combines the source and destination IP addresses. Separate the addresses with a forward slash character. Create a chart of the number of occurrences of the field values.

host="mailserver" | strcat sourceIP "/" destIP comboIP | chart count by comboIP

Example 3:

Add a field called address, which combines the host and port values into the format <host>::<port>.

... | strcat host "::" port address
