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")
Supported functions and syntax
There are two ways that you can see information about the supported evaluation functions:
