mdb searchstack parameter

From reading the documentation, it sounds like when configuring this

parameter you need to strike a balance between potential performance impact if it is too low, and wasted memory if it is too high. While running, is there any way to tell whether or not a search exceeded your configured value and required additional allocation? Whether via the monitor backend, or a log entry, or? Ideally, it would be nice to be able to tell if your configured value was too low and adjust as necessary.

Thanks.
