Public Function CreateObservableUpDownCounter(Of T As Structure) (name As String, observeValues As Func(Of IEnumerable(Of Measurement(Of T))), Optional unit As String = Nothing, Optional description As String = Nothing) As ObservableUpDownCounter(Of T)

Type Parameters

T

The numerical type of the measurement.

Parameters

name

String

The instrument name. Cannot be null.

observeValues

Func<IEnumerable<Measurement<T>>>

The callback to call to get the measurements when the Observe() is called by RecordObservableInstruments().

unit

String

Optional instrument unit of measurements.

description

String

Returns

ObservableUpDownCounter<T>

A new observable up down counter.

Remarks

Example uses for ObservableUpDownCounter: the process heap size or the approximate number of items in a lock-free circular buffer.
