Argument	Description
`online`	Analyze stacks during collection.
`offline`	Analyze stacks after collection.

offline

Set to offline in the following cases:

Survey analysis overhead exceeds 1.1x
A large quantity of data is allocated on the stack, which is a common case for Fortran applications or applications with a large number of small, parallel, OpenMP* regions

Otherwise, set to online. This mode improves stack accuracy but increases overhead.

Run a Survey analysis. Analyze stacks during collection.
