Evaluation functions

Use the evaluation functions to evaluate an expression, based on your events, and return a result.

Quick reference

See the Supported functions and syntax section for a quick reference list of the evaluation functions.

Commands

You can use evaluation functions with the eval, fieldformat, and where commands, and as part of eval expressions with other commands.

Usage

• All functions that accept strings can accept literal strings or any field. 
• All functions that accept numbers can accept literal numbers or any numeric field.

String arguments and fields

For most evaluation functions, when a string argument is expected, you can specify either a literal string or a field name. Literal strings must be enclosed in double quotation marks. In other words, when the function syntax specifies a string you can specify any expression that results in a string. For example, you have a field called name that contains the names of your servers. If you want to append the literal string server at the end of the name, you would use dot notation like this in your search: name."server".​

Nested functions

You can specify a function as an argument to another function.

In the following example, the cidrmatch function is used as the first argument in the if function.

... | eval isLocal=if(cidrmatch("123.132.32.0/25",ip), "local", "not local")

The following example shows how to use the true() function to provide a default to the case function.

... | eval error=case(status == 200, "OK", status == 404, "Not found", true(), "Other")
