Detailed Description

template<typename unit = std::chrono::microseconds>
class Monitored::Timer< unit >

A monitored timer.

The time is measured either between explicit stop/start calls or between the creation and the time the value is read by the monitoring tool.

A strict naming convention is enforced. Timers need to start with the string "TIME_".

Template Parameters

unit	Unit of elapsed time (std::chrono::duration)

Examples

  // The name of the monitored timer has to start with "TIME", else runtime error.
  auto t1 = Monitored::Timer( "TIME_t1" );  // default is microseconds
  auto t2 = Monitored::Timer<std::chrono::milliseconds>( "TIME_t2" );
  {
    auto group = Monitored::Group( monTool, t1, t2 );
    std::this_thread::sleep_for(std::chrono::milliseconds(10));
  }
