Math Expressions

You can use general mathematical expressions on numerical data extracted from log lines. 


| expression [as <field>]


  • The term "expression" is evaluated as a mathematical expression in the context of existing fields.
  • Parentheses can be used to group operations.
  • The ternary operator is supported so you can use "condition ? value_if_true : value_if_false".
  • Supported mathematical operators +, -, *, /, %


  • Boolean expression tests like: disk > 0.8 ? 1 : 0 as overcapacity
  • Math function calls like: min((fps / 10 + 1) * 10, 70) as bucket
  • Assuming x = 1, 2, then ceil(sqrt(x*x + y*y)) as d should result in d = 2.0

Java Math Class

Sumo Logic does not officially support all of Java's Math class functions. 

The Sumo Logic Java library includes the Math class functions, though they are not documented.

The following example uses the pow() function:

| 10 as number | pow(number, 10) as newnumber

To reference Java's Math class functions, see Oracle's Math documentation.
