ObservableUpDownCounter<T> Class

Definition

A metrics-observable instrument that reports increasing or decreasing values when the instrument is being observed. Use this instrument to monitor the process heap size or the approximate number of items in a lock-free circular buffer, for example. To create an ObservableUpDownCounter object, use the CreateObservableUpDownCounter methods.

Properties

Description

Gets the instrument description.

(Inherited from Instrument)
Enabled

Gets a value that indicates if there are any listeners for this instrument.

(Inherited from Instrument)
IsObservable

Gets a value that indicates if the instrument is an observable instrument.

(Inherited from ObservableInstrument<T>)
Meter

Gets the Meter that created the instrument.

(Inherited from Instrument)
Name

Gets the instrument name.

(Inherited from Instrument)
Tags

Returns the tags associated with the instrument.

(Inherited from Instrument)
Unit

Gets the instrument unit of measurements.

Methods

Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object)
GetHashCode()

Serves as the default hash function.

(Inherited from Object)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
Observe()

Fetches the current measurements being tracked by this instrument. All classes extending ObservableInstrument{T} need to implement this method.

(Inherited from ObservableInstrument<T>)
Publish()

Activates the instrument to start recording measurements and to allow listeners to start listening to such measurements.

(Inherited from Instrument)
ToString()

Returns a string that represents the current object.
