Create a performance monitor that collects statistics on a schedule.

Synopsis

Declared in <balb_performancemonitor.h>

PerformanceMonitor(
    bdlmt::TimerEventScheduler* scheduler,
    double interval,
    bslma::Allocator* basicAllocator = 0);

Description

Create an instance of this class that uses the specified scheduler to automatically collect performance statistics every specified interval (specified in seconds). Optionally specify a basicAllocator used to supply memory. If basicAllocator is 0, the currently installed default allocator is used. A non‐positive interval value indicates that performance statistics should not be automatically collected‐‐in this case the user is responsible for manually calling the collect function.
