Member Function Documentation

◆ addSample()

bool isc::perfmon::MonitoredDuration::addSample ( const Duration & sample )

Add a sample to the duration's current interval.

If there is no current interval start a new one otherwise if the current interval has expired move it to the previous interval, set the return flag to true, then start a new interval. Add the sample to the current interval.

Parameters

sample duration value to add

Returns: True if there is a newly completed (i.e. previous) interval to report.

◆ clear()

void isc::perfmon::MonitoredDuration::clear ( )

Deletes the current and previous intervals.

Definition at line 307 of file monitored_duration.cc.

◆ expireCurrentInterval()

void isc::perfmon::MonitoredDuration::expireCurrentInterval ( )

Concludes the current interval.

Rotates current interval to previous and resets curent interval to empty.

Exceptions

InvalidOperation if there is no current interval.
