What is the Sum formula?
The sum() formula adds up all values extracted from your data. Use it to analyze message payloads, context values, or results from other formulas in your log views and search fields.
Syntax
- From Message Body:
sum(body) - From Message Context:
sum(context('MessageContextKey')) - From Nested Formula:
sum(SomeOtherFormula(Content))
Examples: Input, Formula, and Result
Below are practical examples showing exactly what input is used, the formula expression, and the resulting output.

Formula
sum(jsonpath('$..value', body))
Result
4
Example 2: Plain Text Body
