Math processor

The Math processor evaluates arithmetic or logical expressions and stores the result in the target field.

To calculate a value using an expression and store the result in a target field:

1. Select Create → Create processor.
2. Select Math from the Processor menu.
3. Set the Target field where you want to write the expression result.
4. Set your expression in the Expression field. You can directly reference fields in your expression (for example, bytes / duration).

In YAML mode, configure the math processor using the following parameters. For the complete Streamlang syntax, refer to the Streamlang reference.

- action: math
  expression: "attributes.bytes / attributes.duration"
  to: attributes.throughput
