## [Unreleased]
## [1.15.1/0.38.1] 2023-05-02
### Fixed
- Remove unused imports from `sdk/resource/host_id_bsd.go` which caused build failures. (#4040, #4041)
## [1.15.0/0.38.0] 2023-04-27
### Added

- The `Version` function to `go.opentelemetry.io/otel/sdk` to return the SDK version. (#3949)
- Add a `WithNamespace` option to `go.opentelemetry.io/otel/exporters/prometheus` to allow users to prefix metrics with a namespace. (#3970)
- The following configuration types were added to `go.opentelemetry.io/otel/metric/instrument` to be used in the configuration of measurement methods. (#3971)
- The `AddConfig` used to hold configuration for addition measurements
- `NewAddConfig` used to create a new `AddConfig`
- `AddOption` used to configure an `AddConfig`
- The `RecordConfig` used to hold configuration for recorded measurements
- `NewRecordConfig` used to create a new `RecordConfig`
- `RecordOption` used to configure a `RecordConfig`
- The `ObserveConfig` used to hold configuration for observed measurements
- `NewObserveConfig` used to create a new `ObserveConfig`
- `ObserveOption` used to configure an `ObserveConfig`
- `WithAttributeSet` and `WithAttributes` are added to `go.opentelemetry.io/otel/metric/instrument`.
They return an option used during a measurement that defines the attribute Set associated with the measurement. (#3971)
- The `Version` function to `go.opentelemetry.io/otel/exporters/otlp/otlpmetric` to return the OTLP metrics client version. (#3956)

### Changed
- The `Extrema` in `go.opentelemetry.io/otel/sdk/metric/metricdata` is redefined with a generic argument of `[N int64 | float64]`. (#3870)
- Update all exported interfaces from `go.opentelemetry.io/otel/metric` to embed their corresponding interface from `go.opentelemetry.io/otel/metric/embedded`.
This adds an implementation requirement to set the interface default behavior for unimplemented methods. (#3916)
- Move No-Op implementation from `go.opentelemetry.io/otel/metric` into its own package `go.opentelemetry.io/otel/metric/noop`. (#3941)

- Add all the methods from `"go.opentelemetry.io/otel/trace".SpanContext` to `bridgeSpanContext` by embedding `otel.SpanContext` in `bridgeSpanContext`. (#3966)
- Wrap `UploadMetrics` error in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/` to improve error message when encountering generic grpc errors. (#3974)
- The measurement methods for all instruments in `go.opentelemetry.io/otel/metric/instrument` accept an option instead of the variadic `"go.opentelemetry.io/otel/attribute".KeyValue`. (#3971)
- The `Int64Counter.Add` method now accepts `...AddOption`
- The `Float64Counter.Add` method now accepts `...AddOption`
- The `Int64UpDownCounter.Add` method now accepts `...AddOption`
- The `Float64UpDownCounter.Add` method now accepts `...AddOption`

- The `Float64Observer.Observe` method now accepts `...ObserveOption`
- The `Observer` methods in `go.opentelemetry.io/otel/metric` accept an option instead of the variadic `"go.opentelemetry.io/otel/attribute".KeyValue`. (#3971)
- The `Observer.ObserveInt64` method now accepts `...ObserveOption`
- The `Observer.ObserveFloat64` method now accepts `...ObserveOption`
- Move global metric back to `go.opentelemetry.io/otel/metric/global` from `go.opentelemetry.io/otel`. (#3986)
### Fixed
- `TracerProvider` allows calling `Tracer()` while it's shutting down.
It used to deadlock. (#3924)
- Use the SDK version for the Telemetry SDK resource detector in `go.opentelemetry.io/otel/sdk/resource`. (#3949)
- Fix a data race in `SpanProcessor` returned by `NewSimpleSpanProcessor` in `go.opentelemetry.io/otel/sdk/trace`. (#3951)
- Automatically figure out the default aggregation with `aggregation.Default`. (#3967)
### Deprecated
- The `go.opentelemetry.io/otel/metric/instrument` package is deprecated.
Use the equivalent types added to `go.opentelemetry.io/otel/metric` instead. (#4018)
## [1.15.0-rc.2/0.38.0-rc.2] 2023-03-23
This is a release candidate for the v1.15.0/v0.38.0 release.
That release will include the `v1` release of the OpenTelemetry Go metric API and will provide stability guarantees of that API.

### Added
- The `WithHostID` option to `go.opentelemetry.io/otel/sdk/resource`. (#3812)
- The `WithoutTimestamps` option to `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric` to sets all timestamps to zero. (#3828)
- The new `Exemplar` type is added to `go.opentelemetry.io/otel/sdk/metric/metricdata`.
Both the `DataPoint` and `HistogramDataPoint` types from that package have a new field of `Exemplars` containing the sampled exemplars for their timeseries. (#3849)
- Configuration for each metric instrument in `go.opentelemetry.io/otel/sdk/metric/instrument`. (#3895)

- Both the `Histogram` and `HistogramDataPoint` are redefined with a generic argument of `[N int64 | float64]` in `go.opentelemetry.io/otel/sdk/metric/metricdata`. (#3849)
- The metric `Export` interface from `go.opentelemetry.io/otel/sdk/metric` accepts a `*ResourceMetrics` instead of `ResourceMetrics`. (#3853)
- Rename `Asynchronous` to `Observable` in `go.opentelemetry.io/otel/metric/instrument`. (#3892)
- Rename `Int64ObserverOption` to `Int64ObservableOption` in `go.opentelemetry.io/otel/metric/instrument`. (#3895)

### How to Get PRs Merged
A PR is considered to be **ready to merge** when:
A PR is considered **ready to merge** when:
* It has received two approvals from Collaborators/Maintainers (at
different companies). This is not enforced through technical means
and a PR may be **ready to merge** with a single approval if the change
and its approach have been discussed and consensus reached.
* Feedback has been addressed.
* Any substantive changes to your PR will require that you clear any prior
Approval reviews, this includes changes resulting from other feedback. Unless
the approver explicitly stated that their approval will persist across
changes it should be assumed that the PR needs their review again. Other
project members (e.g. approvers, maintainers) can help with this if there are
any questions or if you forget to clear reviews.
* It has been open for review for at least one working day. This gives
people reasonable time to review.
* Trivial changes (typo, cosmetic, doc, etc.) do not have to wait for
one day and may be merged with a single Maintainer's approval.
* `CHANGELOG.md` has been updated to reflect what has been
added, changed, removed, or fixed.
* `README.md` has been updated if necessary.
* Urgent fix can take exception as long as it has been actively
communicated.
* It has received two qualified approvals[^1].
Any Maintainer can merge the PR once it is **ready to merge**.
This is not enforced through automation, but needs to be validated by the
maintainer merging.
* The qualified approvals need to be from [Approver]s/[Maintainer]s
affiliated with different companies. Two qualified approvals from
[Approver]s or [Maintainer]s affiliated with the same company counts as a
single qualified approval.
* PRs introducing changes that have already been discussed and consensus
reached only need one qualified approval. The discussion and resolution
needs to be linked to the PR.
* Trivial changes[^2] only need one qualified approval.
* All feedback has been addressed.
* All PR comments and suggestions are resolved.
* All GitHub Pull Request reviews with a status of "Request changes" have
been addressed. Another review by the objecting reviewer with a different
status can be submitted to clear the original review, or the review can be
dismissed by a [Maintainer] when the issues from the original review have
been addressed.
* Any comments or reviews that cannot be resolved between the PR author and
reviewers can be submitted to the community [Approver]s and [Maintainer]s
during the weekly SIG meeting. If consensus is reached among the
[Approver]s and [Maintainer]s during the SIG meeting the objections to the
PR may be dismissed or resolved or the PR closed by a [Maintainer].
* Any substantive changes to the PR require existing Approval reviews be
cleared unless the approver explicitly states that their approval persists
across changes. This includes changes resulting from other feedback.
[Approver]s and [Maintainer]s can help in clearing reviews and they should
be consulted if there are any questions.
* The PR branch is up to date with the base branch it is merging into.
* To ensure this does not block the PR, it should be configured to allow
maintainers to update it.
* It has been open for review for at least one working day. This gives people
reasonable time to review.
* Trivial changes[^2] do not have to wait for one day and may be merged with
a single [Maintainer]'s approval.
* All required GitHub workflows have succeeded.
* Urgent fix can take exception as long as it has been actively communicated
among [Maintainer]s.
Any [Maintainer] can merge the PR once the above criteria have been met.
[^1]: A qualified approval is a GitHub Pull Request review with "Approve"
status from an OpenTelemetry Go [Approver] or [Maintainer].
[^2]: Trivial changes include: typo corrections, cosmetic non-substantive
changes, documentation corrections or updates, dependency updates, etc.

/*
Package metric provides an implementation of the metrics part of the
OpenTelemetry API.
Package metric provides the OpenTelemetry API used to measure metrics about
source code operation.
This package is currently in a pre-GA phase. Backwards incompatible changes
may be introduced in subsequent minor version releases as we work to track the
evolving OpenTelemetry specification and user feedback.
This API is separate from its implementation so the instrumentation built from
it is reusable. See [go.opentelemetry.io/otel/sdk/metric] for the official
OpenTelemetry implementation of this API.
All measurements made with this package are made via instruments. These
instruments are created by a [Meter] which itself is created by a
[MeterProvider]. Applications need to accept a [MeterProvider] implementation
as a starting point when instrumenting. This can be done directly, or by using
the OpenTelemetry global MeterProvider via [GetMeterProvider]. Using an
appropriately named [Meter] from the accepted [MeterProvider], instrumentation
can then be built from the [Meter]'s instruments.
# Instruments
Each instrument is designed to make measurements of a particular type. Broadly,
all instruments fall into two overlapping logical categories: asynchronous or
synchronous, and int64 or float64.
All synchronous instruments ([Int64Counter], [Int64UpDownCounter],
[Int64Histogram], [Float64Counter], [Float64UpDownCounter], [Float64Histogram])
are used to measure the operation and performance of source code during the
source code execution. These instruments only make measurements when the source
code they instrument is run.
All asynchronous instruments ([Int64ObservableCounter],
[Int64ObservableUpDownCounter], [Int64ObservableGauge],
[Float64ObservableCounter], [Float64ObservableUpDownCounter],
[Float64ObservableGauge]) are used to measure metrics outside of the execution
of source code. They are said to make "observations" via a callback function
called once every measurement collection cycle.
Each instrument is also grouped by the value type it measures. Either int64 or
float64. The value being measured will dictate which instrument in these
categories to use.
Outside of these two broad categories, instruments are described by the
function they are designed to serve. All Counters ([Int64Counter],
[Float64Counter], [Int64ObservableCounter], [Float64ObservableCounter]) are
designed to measure values that never decrease in value, but instead only
incrementally increase in value. UpDownCounters ([Int64UpDownCounter],
[Float64UpDownCounter], [Int64ObservableUpDownCounter],
[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
collection cycle, a Histogram ([Int64Histogram], [Float64Histogram]) should be
used. Finally, when just the most recent measurement needs to be conveyed about an
asynchronous measurement, a Gauge ([Int64ObservableGauge],
[Float64ObservableGauge]) should be used.
See the [OpenTelemetry documentation] for more information about instruments
and their intended use.
# API Implementations
This package does not conform to the standard Go versioning policy, all of its
interfaces may have methods added to them without a package major version bump.
This non-standard API evolution could surprise an uninformed implementation
author. They could unknowingly build their implementation in a way that would
result in a runtime panic for their users that update to the new API.
The API is designed to help inform an instrumentation author about this
non-standard API evolution. It requires them to choose a default behavior for
unimplemented interface methods. There are three behavior choices they can
make:
- Compilation failure
- Panic
- Default to another implementation
All interfaces in this API embed a corresponding interface from
[go.opentelemetry.io/otel/metric/embedded]. If an author wants the default
behavior of their implementations to be a compilation failure, signaling to
their users they need to update to the latest version of that implementation,
they need to embed the corresponding interface from
[go.opentelemetry.io/otel/metric/embedded] in their implementation. For
example,
import "go.opentelemetry.io/otel/metric/embedded"
type MeterProvider struct {
embedded.MeterProvider
// ...
}
If an author wants the default behavior of their implementations to a panic,
they need to embed the API interface directly.
import "go.opentelemetry.io/otel/metric"
type MeterProvider struct {
metric.MeterProvider
// ...
}
This is not a recommended behavior as it could lead to publishing packages that
contain runtime panics when users update other package that use newer versions
of [go.opentelemetry.io/otel/metric].
Finally, an author can embed another implementation in theirs. The embedded
implementation will be used for methods not defined by the author. For example,
an author who want to default to silently dropping the call can use
[go.opentelemetry.io/otel/metric/noop]:
import "go.opentelemetry.io/otel/metric/noop"
type MeterProvider struct {
noop.MeterProvider
// ...
}
It is strongly recommended that authors only embed
[go.opentelemetry.io/otel/metric/noop] if they choose this default behavior.
That implementation is the only one OpenTelemetry authors can guarantee will
fully implement all the API interfaces when a user updates their API.
