Synchronous instruments are called by the user with a -Context. Asynchronous instruments are called by the SDK during collection. -Additive instruments are semantically intended for capturing a sum. Grouping -instruments are intended for capturing a distribution. - -Additive instruments may be monotonic, in which case they are non-decreasing -and naturally define a rate. - -The synchronous instrument names are: - - Counter: additive, monotonic - UpDownCounter: additive - ValueRecorder: grouping - -and the asynchronous instruments are: - - SumObserver: additive, monotonic - UpDownSumObserver: additive - ValueObserver: grouping - -All instruments are provided with support for either float64 or int64 input -values. - -An instrument is created using a Meter. Additionally, a Meter is used to -record batches of synchronous measurements or asynchronous observations. A -Meter is obtained using a MeterProvider. A Meter, like a Tracer, is unique to -the instrumentation it instruments and must be named and versioned when -created with a MeterProvider with the name and version of the instrumentation -library. - -Instrumentation should be designed to accept a MeterProvider from which it can -create its own unique Meter.
