Create iPoints nested in JSON Values of Variables

[e0x70i]

Supports creating insertion points on Variables whose value is JSON. Will iterate through the JSON adding insertion points to every JSON primitive in the tree.

For example

{"testType":["test1","test2"],"test2Type":["test1"],"test3":["three"],"count":5} generates the following insertion points [var]testType[0]:index [var]testType[1]:metric [var]test2Type[0]:test1 [var]test3[0]:three [var]count:5
