What is the Length formula?
The Length() formula returns the length of 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:
Length(body, [bool unique = true]) - From Message Context:
Length(context('MessageContextKey'), [bool unique = true]) - From Nested Formula:
Length(SomeOtherFormula(Content), [bool unique = true])
Examples: Input, Formula, and Result
Below are practical examples showing exactly what input is used, the formula expression, and the resulting output.
Example 1: XML Message Body
Input
<ns0:Orders xmlns:ns0="SupplyChain.Schemas/1.0">
<Order>
<Id>1337</Id>
<Amount>666</Amount>
<City>New York</City>
<Partner>QWNtZQ==</Partner>
</Order>
</ns0:Orders>
Formula
Length(xpath('Orders/Order/City', body))
Result
8
Example 2: Plain Text Body
Input
Nodinite
Formula
Length(body)
Result
8
The result is 8 because the message body contains 8 characters.
Example 3: Message Context Value
Input
demo001
Formula
Length(context('id'))
Result
7
The result is 7 because the context value for 'id' is 7 characters long.
Example 4: JSON with Nested Formula
Input
{"a":[{"b":"This"},{"b":"is"},{"b":"Formula Plugin"}]}
Formula
Length(jsonpath('a[*].b', body))
Result
4, 2, 14
The result is 4, 2, and 14 because the extracted values have those lengths.
