class StallObserver

Defined at line 83 of file ../../zircon/kernel/lib/stall/include/lib/stall.h

A stall observer that keeps a circular queue with the last N samples (where N corresponds to the

number of samples covering the requested time window).

Every time a new sample is pushed into it, it tests if the sum of all the stored samples is

greater than or equal to the given threshold value and then notifies its callback function

accordingly.

This class doesn't need to be thread safe because all its usages are protected by the

StallAggregator's observers_lock_.
