Member Function Documentation

GetCounter() [1/2]

std::shared_ptr< Counter > iceberg::MetricsContext::GetCounter ( std::string_view  name )

inline

Get or create a count-unit Counter by name.

Convenience overload defaulting to CounterUnit::kCount.

GetCounter() [2/2]

virtual std::shared_ptr< Counter > iceberg::MetricsContext::GetCounter ( std::string_view  name, CounterUnit  unit  )

pure virtual

Get or create a named Counter with an explicit unit.

Implemented in iceberg::DefaultMetricsContext, and iceberg::DefaultMetricsContext.

GetTimer() [1/2]

std::shared_ptr< Timer > iceberg::MetricsContext::GetTimer ( std::string_view  name )

inline

Get or create a nanosecond-precision Timer by name.

Convenience overload defaulting to TimerUnit::kNanoseconds.

GetTimer() [2/2]

virtual std::shared_ptr< Timer > iceberg::MetricsContext::GetTimer ( std::string_view  name, TimerUnit  unit  )

pure virtual

Get or create a named Timer with an explicit unit.

Implemented in iceberg::DefaultMetricsContext, and iceberg::DefaultMetricsContext.

Noop()

const std::shared_ptr< MetricsContext > & iceberg::MetricsContext::Noop ( )

static

Return the no-op MetricsContext singleton.

All metrics returned by the no-op context are noop; nothing is allocated.
