Outside of these two broad categories, instruments are described by the
function they are designed to serve. All Counters ([Int64Counter],
[Float64Counter], [Int64ObservableCounter], [Float64ObservableCounter]) are
[Float64Counter], [Int64ObservableCounter], and [Float64ObservableCounter]) are
designed to measure values that never decrease in value, but instead only
incrementally increase in value. UpDownCounters ([Int64UpDownCounter],

[Float64UpDownCounter], [Int64ObservableUpDownCounter], and
[Float64ObservableUpDownCounter]) on the other hand, are designed to measure
values that can increase and decrease. When more information
needs to be conveyed about all the synchronous measurements made during a

and their intended use.
# Measurements
Measurements are made by recording values and information about the values with
an instrument. How these measurements are recorded depends on the instrument.
Measurements for synchronous instruments ([Int64Counter], [Int64UpDownCounter],
[Int64Histogram], [Float64Counter], [Float64UpDownCounter], and
[Float64Histogram]) are recorded using the instrument methods directly. All
counter instruments have an Add method that is used to measure an increment
value, and all histogram instruments have a Record method to measure a data
point.
Asynchronous instruments ([Int64ObservableCounter],
[Int64ObservableUpDownCounter], [Int64ObservableGauge],
[Float64ObservableCounter], [Float64ObservableUpDownCounter], and
[Float64ObservableGauge]) record measurements within a callback function. The
callback is registered with the Meter which ensures the callback is called once
per collection cycle. A callback can be registered two ways: during the
instrument's creation using an option, or later using the RegisterCallback
method of the [Meter] that created the instrument.
If the following criteria are met, an option ([WithInt64Callback] or
[WithFloat64Callback]) can be used during the asynchronous instrument's
creation to register a callback ([Int64Callback] or [Float64Callback],
respectively):
- The measurement process is known when the instrument is created
- Only that instrument will make a measurement within the callback
- The callback never needs to be unregistered
If the criteria are not met, use the RegisterCallback method of the [Meter] that
created the instrument to register a [Callback].
