# Contributing to opentelemetry-go-contrib
The Go special interest group (SIG) meets regularly. See the
OpenTelemetry
[community](https://github.com/open-telemetry/community#golang-sdk)
repo for information on this and other language SIGs.
See the [public meeting
notes](https://docs.google.com/document/d/1A63zSWX0x2CyCK_LoNhmQC4rqhLpYXJzXbEPDUQ2n6w/edit#heading=h.9tngw7jdwd6b)
for a summary description of past meetings. To request edit access,
join the meeting or get in touch on
[Slack](https://cloud-native.slack.com/archives/C01NPAXACKT).
## Development
There are some generated files checked into the repo. To make sure
that the generated files are up-to-date, run `make` (or `make
precommit` - the `precommit` target is the default).
The `precommit` target also fixes the formatting of the code and
checks the status of the go module files.
If after running `make precommit` the output of `git status` contains
`nothing to commit, working tree clean` then it means that everything
is up-to-date and properly formatted.
## Pull Requests
### How to Send Pull Requests
Everyone is welcome to contribute code to `opentelemetry-go-contrib` via
GitHub pull requests (PRs).
To create a new PR, fork the project in GitHub and clone the upstream
repo:
```sh
$ git clone https://github.com/open-telemetry/opentelemetry-go-contrib
```
This would put the project in the `opentelemetry-go-contrib` directory in
current working directory.
Enter the newly created directory and add your fork as a new remote:
```sh
$ git remote add <YOUR_FORK> git@github.com:<YOUR_GITHUB_USERNAME>/opentelemetry-go
```
Check out a new branch, make modifications, run linters and tests, update
`CHANGELOG.md` and push the branch to your fork:
```sh
$ git checkout -b <YOUR_BRANCH_NAME>
# edit files
# update changelog
$ make precommit
$ git add -p
$ git commit
$ git push <YOUR_FORK> <YOUR_BRANCH_NAME>
```
Open a pull request against the main `opentelemetry-go-contrib` repo. Be sure to add the pull
request ID to the entry you added to `CHANGELOG.md`.
### How to Receive Comments
* If the PR is not ready for review, please put `[WIP]` in the title,
tag it as `work-in-progress`, or mark it as
[`draft`](https://github.blog/2019-02-14-introducing-draft-pull-requests/).
* Make sure CLA is signed and CI is clear.
### How to Get PRs Merged
A PR is considered to be **ready to merge** when:
* It has received two approvals from Approvers/Maintainers (at
different companies).
* 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 change (typo, cosmetic, doc, etc.) doesn't have to wait for
one day.
* `CHANGELOG.md` has been updated to reflect what has been
added, changed, removed, or fixed.
* Urgent fix can take exception as long as it has been actively
communicated.
Any Maintainer can merge the PR once it is **ready to merge**.
## Style Guide
* Make sure to run `make precommit` - this will find and fix the code
formatting.
* Check [opentelemetry-go Style Guide](https://github.com/open-telemetry/opentelemetry-go/blob/main/CONTRIBUTING.md#style-guide)
## Adding a new Contrib package
To add a new contrib package follow an existing one. An empty Sample instrumentation
provides base structure with an example and a test. Each contrib package
should be its own module. A contrib package may contain more than one go package.
### Folder Structure
- instrumentation/\<instrumentation-package> (**Common**)
- instrumentation/\<instrumentation-package>/trace (**specific to trace**)
- instrumentation/\<instrumentation-package>/metrics (**specific to metrics**)
#### Example
- instrumentation/gorm/trace
- instrumentation/kafka/metrics

# Release Process
There are two types of release for the `go.opentelemetry.io/contrib` repo
and submodules.
1. **Case 1** A release due to changes independent of the
`go.opentelemetry.io/otel` module, e.g. perhaps a critical bug fix in
one of the contrib modules.
2. **Case 2** A release due to a breaking API change in
`go.opentelemetry.io/otel` which all modules in this repo
depend on.
## Pre-Release
Update go.mod for submodules to depend on the upcoming new release of
the module in this repo, `go.opentelemetry.io/contrib`. Decide on the
next version of the semantic tag to apply to the contrib
module based on whether you fall into Case 1 or Case 2.
### Case 1
If the changes are all internal to this repo, then the new tag will
most often be a patch or minor version upgrade to the existing tag on
this module. Let's call this `<new_contrib_tag>`.
### Case 2
If a new release is required due to breaking changes in
`go.opentelemetry.io/otel`, then the new semantic tag for this repo
should be bumped to match the `go.opentelemetry.io/otel` new tag.
Let's call this `<new_otel_tag>`. The script checks that
`go.opentelemetry.io/otel@v<new_otel_tag>` is a valid tag, so you need
to wait until that tag has been pushed in the main repo.
In nearly all cases, `<new_contrib_tag>` should be the same as
`<new_otel_tag>`.
1. Run `pre_release.sh` script to create a branch `pre_release_<new_contrib_tag>`.
The script will also run `go mod tidy` and `make ci`.
* **Case 1** `./pre_release.sh -t <new_contrib_tag>`
* **Case 2** `./pre_release.sh -o <new_otel_tag> [-t <new_contrib_tag>]`
2. If you used `-o <new_otel_tag>` to rewrite the modules to depend on
a new version of `go.opentelemetry.io/otel`, there will likely be
breaking changes that require fixes to the files in this
`contrib` repo. Make the appropriate fixes to address any API
breaks and run through the
```
git commit -m "fixes due to API changes"
make precommit
```
cycle until everything passes
4. Push the changes to upstream.
```
git diff main
git push
```
5. Create a PR on github and merge the PR once approved.
### Tag
Now create a `<new_contrib_tag>` on the commit hash of the changes made in pre-release step,
1. Run the tag.sh script.
```
./tag.sh <new_contrib_tag> <commit-hash>
```
2. Push tags upstream. Make sure you push upstream for all the sub-module tags as well.
```
git push upstream <new_contrib_tag>
git push upstream <submodules-path/new_contrib_tag>
...
```
## Release
Now create a release for the new `<new_contrib_tag>` on github.
The release body should include all the release notes in the Changelog for this release.
Additionally, the `tag.sh` script generates commit logs since last release which can be used to suppliment the release notes.
<!-- ## Verify Examples -->
<!-- After releasing run following script to verify that examples build outside of the otel repo. -->
<!-- The script copies examples into a different directory and builds them. -->
<!-- ``` -->
<!-- ./verify_examples.sh -->
<!-- ``` -->

@ -8,17 +8,199 @@ This project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.htm
## [Unreleased]
## [1.2.0] - 2021-11-12
## Changed
- Metric SDK `export.ExportKind`, `export.ExportKindSelector` types have been renamed to `aggregation.Temporality` and `aggregation.TemporalitySelector` respectively to keep in line with current specification and protocol along with built-in selectors (e.g., `aggregation.CumulativeTemporalitySelector`, ...). (#2274)
- The Metric `Exporter` interface now requires a `TemporalitySelector` method instead of an `ExportKindSelector`. (#2274)
- Metrics API cleanup. The `metric/sdkapi` package has been created to relocate the API-to-SDK interface:
- The following interface types simply moved from `metric` to `metric/sdkapi`: `Descriptor`, `MeterImpl`, `InstrumentImpl`, `SyncImpl`, `BoundSyncImpl`, `AsyncImpl`, `AsyncRunner`, `AsyncSingleRunner`, and `AsyncBatchRunner`
- The following struct types moved and are replaced with type aliases, since they are exposed to the user: `Observation`, `Measurement`.
- The No-op implementations of sync and async instruments are no longer exported, new functions `sdkapi.NewNoopAsyncInstrument()` and `sdkapi.NewNoopSyncInstrument()` are provided instead. (#2271)
- Update the SDK `BatchSpanProcessor` to export all queued spans when `ForceFlush` is called. (#2080, #2335)
### Added
- Add the `"go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc".WithGRPCConn` option so the exporter can reuse an existing gRPC connection. (#2002)
- Added a new `schema` module to help parse Schema Files in OTEP 0152 format. (#2267)
- Added a new `MapCarrier` to the `go.opentelemetry.io/otel/propagation` package to hold propagated coss-cutting concerns as a `map[string]string` held in memory. (#2334)
## [1.1.0] - 2021-10-27
### Added
- Add the `"go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc".WithGRPCConn` option so the exporter can reuse an existing gRPC connection. (#2002)
- Add the `go.opentelemetry.io/otel/semconv/v1.7.0` package.
The package contains semantic conventions from the `v1.7.0` version of the OpenTelemetry specification. (#2320)
- Add the `go.opentelemetry.io/otel/semconv/v1.6.1` package.
The package contains semantic conventions from the `v1.6.1` version of the OpenTelemetry specification. (#2321)
- Add the `go.opentelemetry.io/otel/semconv/v1.5.0` package.
The package contains semantic conventions from the `v1.5.0` version of the OpenTelemetry specification. (#2322)
- When upgrading from the `semconv/v1.4.0` package note the following name changes:
- `K8SReplicasetUIDKey` -> `K8SReplicaSetUIDKey`
- `K8SReplicasetNameKey` -> `K8SReplicaSetNameKey`
- `K8SStatefulsetUIDKey` -> `K8SStatefulSetUIDKey`
- `k8SStatefulsetNameKey` -> `K8SStatefulSetNameKey`
- `K8SDaemonsetUIDKey` -> `K8SDaemonSetUIDKey`
- `K8SDaemonsetNameKey` -> `K8SDaemonSetNameKey`
### Changed
### Deprecated
### Removed
- Links added to a span will be dropped by the SDK if they contain an invalid span context (#2275).
### Fixed
### Security
- The `"go.opentelemetry.io/otel/semconv/v1.4.0".HTTPServerAttributesFromHTTPRequest` now correctly only sets the HTTP client IP attribute even if the connection was routed with proxies and there are multiple addresses in the `X-Forwarded-For` header. (#2282, #2284)
- The `"go.opentelemetry.io/otel/semconv/v1.4.0".NetAttributesFromHTTPRequest` function correctly handles IPv6 addresses as IP addresses and sets the correct net peer IP instead of the net peer hostname attribute. (#2283, #2285)
- The simple span processor shutdown method deterministically returns the exporter error status if it simultaneously finishes when the deadline is reached. (#2290, #2289)
## [1.0.1] - 2021-10-01
### Fixed
- json stdout exporter no longer crashes due to concurrency bug. (#2265)
## [Metrics 0.24.0] - 2021-10-01
### Changed
- NoopMeterProvider is now private and NewNoopMeterProvider must be used to obtain a noopMeterProvider. (#2237)
- The Metric SDK `Export()` function takes a new two-level reader interface for iterating over results one instrumentation library at a time. (#2197)
- The former `"go.opentelemetry.io/otel/sdk/export/metric".CheckpointSet` is renamed `Reader`.
- The new interface is named `"go.opentelemetry.io/otel/sdk/export/metric".InstrumentationLibraryReader`.
## [1.0.0] - 2021-09-20
This is the first stable release for the project.
This release includes an API and SDK for the tracing signal that will comply with the stability guarantees defined by the projects [versioning policy](./VERSIONING.md).
### Added
- OTLP trace exporter now sets the `SchemaURL` field in the exported telemetry if the Tracer has `WithSchemaURL` option. (#2242)
### Fixed
- Slice-valued attributes can correctly be used as map keys. (#2223)
### Removed
- Removed the `"go.opentelemetry.io/otel/exporters/zipkin".WithSDKOptions` function. (#2248)
- Removed the deprecated package `go.opentelemetry.io/otel/oteltest`. (#2234)
- Removed the deprecated package `go.opentelemetry.io/otel/bridge/opencensus/utils`. (#2233)
- Removed deprecated functions, types, and methods from `go.opentelemetry.io/otel/attribute` package.
Use the typed functions and methods added to the package instead. (#2235)
- The `Key.Array` method is removed.
- The `Array` function is removed.
- The `Any` function is removed.
- The `ArrayValue` function is removed.
- The `AsArray` function is removed.
## [1.0.0-RC3] - 2021-09-02
### Added
- Added `ErrorHandlerFunc` to use a function as an `"go.opentelemetry.io/otel".ErrorHandler`. (#2149)
- Added `"go.opentelemetry.io/otel/trace".WithStackTrace` option to add a stack trace when using `span.RecordError` or when panic is handled in `span.End`. (#2163)
- Added typed slice attribute types and functionality to the `go.opentelemetry.io/otel/attribute` package to replace the existing array type and functions. (#2162)
- `BoolSlice`, `IntSlice`, `Int64Slice`, `Float64Slice`, and `StringSlice` replace the use of the `Array` function in the package.
- Added the `go.opentelemetry.io/otel/example/fib` example package.
Included is an example application that computes Fibonacci numbers. (#2203)
### Changed
- Metric instruments have been renamed to match the (feature-frozen) metric API specification:
- ValueRecorder becomes Histogram
- ValueObserver becomes Gauge
- SumObserver becomes CounterObserver
- UpDownSumObserver becomes UpDownCounterObserver
The API exported from this project is still considered experimental. (#2202)
- Metric SDK/API implementation type `InstrumentKind` moves into `sdkapi` sub-package. (#2091)
- The Metrics SDK export record no longer contains a Resource pointer, the SDK `"go.opentelemetry.io/otel/sdk/trace/export/metric".Exporter.Export()` function for push-based exporters now takes a single Resource argument, pull-based exporters use `"go.opentelemetry.io/otel/sdk/metric/controller/basic".Controller.Resource()`. (#2120)
- The JSON output of the `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` is harmonized now such that the output is "plain" JSON objects after each other of the form `{ ... } { ... } { ... }`. Earlier the JSON objects describing a span were wrapped in a slice for each `Exporter.ExportSpans` call, like `[ { ... } ][ { ... } { ... } ]`. Outputting JSON object directly after each other is consistent with JSON loggers, and a bit easier to parse and read. (#2196)
- Update the `NewTracerConfig`, `NewSpanStartConfig`, `NewSpanEndConfig`, and `NewEventConfig` function in the `go.opentelemetry.io/otel/trace` package to return their respective configurations as structs instead of pointers to the struct. (#2212)
### Deprecated
- The `go.opentelemetry.io/otel/bridge/opencensus/utils` package is deprecated.
All functionality from this package now exists in the `go.opentelemetry.io/otel/bridge/opencensus` package.
The functions from that package should be used instead. (#2166)
- The `"go.opentelemetry.io/otel/attribute".Array` function and the related `ARRAY` value type is deprecated.
Use the typed `*Slice` functions and types added to the package instead. (#2162)
- The `"go.opentelemetry.io/otel/attribute".Any` function is deprecated.
Use the typed functions instead. (#2181)
- The `go.opentelemetry.io/otel/oteltest` package is deprecated.
The `"go.opentelemetry.io/otel/sdk/trace/tracetest".SpanRecorder` can be registered with the default SDK (`go.opentelemetry.io/otel/sdk/trace`) as a `SpanProcessor` and used as a replacement for this deprecated package. (#2188)
### Removed
- Removed metrics test package `go.opentelemetry.io/otel/sdk/export/metric/metrictest`. (#2105)
### Fixed
- The `fromEnv` detector no longer throws an error when `OTEL_RESOURCE_ATTRIBUTES` environment variable is not set or empty. (#2138)
- Setting the global `ErrorHandler` with `"go.opentelemetry.io/otel".SetErrorHandler` multiple times is now supported. (#2160, #2140)
- The `"go.opentelemetry.io/otel/attribute".Any` function now supports `int32` values. (#2169)
- Multiple calls to `"go.opentelemetry.io/otel/sdk/metric/controller/basic".WithResource()` are handled correctly, and when no resources are provided `"go.opentelemetry.io/otel/sdk/resource".Default()` is used. (#2120)
- The `WithoutTimestamps` option for the `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` exporter causes the exporter to correctly ommit timestamps. (#2195)
- Fixed typos in resources.go. (#2201)
## [1.0.0-RC2] - 2021-07-26
### Added
- Added `WithOSDescription` resource configuration option to set OS (Operating System) description resource attribute (`os.description`). (#1840)
- Added `WithOS` resource configuration option to set all OS (Operating System) resource attributes at once. (#1840)
- Added the `WithRetry` option to the `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` package.
This option is a replacement for the removed `WithMaxAttempts` and `WithBackoff` options. (#2095)
- Added API `LinkFromContext` to return Link which encapsulates SpanContext from provided context and also encapsulates attributes. (#2115)
- Added a new `Link` type under the SDK `otel/sdk/trace` package that counts the number of attributes that were dropped for surpassing the `AttributePerLinkCountLimit` configured in the Span's `SpanLimits`.
This new type replaces the equal-named API `Link` type found in the `otel/trace` package for most usages within the SDK.
For example, instances of this type are now returned by the `Links()` function of `ReadOnlySpan`s provided in places like the `OnEnd` function of `SpanProcessor` implementations. (#2118)
- Added the `SpanRecorder` type to the `go.opentelemetry.io/otel/skd/trace/tracetest` package.
This type can be used with the default SDK as a `SpanProcessor` during testing. (#2132)
### Changed
- The `SpanModels` function is now exported from the `go.opentelemetry.io/otel/exporters/zipkin` package to convert OpenTelemetry spans into Zipkin model spans. (#2027)
- Rename the `"go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc".RetrySettings` to `RetryConfig`. (#2095)
### Deprecated
- The `TextMapCarrier` and `TextMapPropagator` from the `go.opentelemetry.io/otel/oteltest` package and their associated creation functions (`TextMapCarrier`, `NewTextMapPropagator`) are deprecated. (#2114)
- The `Harness` type from the `go.opentelemetry.io/otel/oteltest` package and its associated creation function, `NewHarness` are deprecated and will be removed in the next release. (#2123)
- The `TraceStateFromKeyValues` function from the `go.opentelemetry.io/otel/oteltest` package is deprecated.
Use the `trace.ParseTraceState` function instead. (#2122)
### Removed
- Removed the deprecated package `go.opentelemetry.io/otel/exporters/trace/jaeger`. (#2020)
- Removed the deprecated package `go.opentelemetry.io/otel/exporters/trace/zipkin`. (#2020)
- Removed the `"go.opentelemetry.io/otel/sdk/resource".WithBuiltinDetectors` function.
The explicit `With*` options for every built-in detector should be used instead. (#2026 #2097)
- Removed the `WithMaxAttempts` and `WithBackoff` options from the `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` package.
The retry logic of the package has been updated to match the `otlptracegrpc` package and accordingly a `WithRetry` option is added that should be used instead. (#2095)
- Removed `DroppedAttributeCount` field from `otel/trace.Link` struct. (#2118)
### Fixed
- When using WithNewRoot, don't use the parent context for making sampling decisions. (#2032)
- `oteltest.Tracer` now creates a valid `SpanContext` when using `WithNewRoot`. (#2073)
- OS type detector now sets the correct `dragonflybsd` value for DragonFly BSD. (#2092)
- The OTel span status is correctly transformed into the OTLP status in the `go.opentelemetry.io/otel/exporters/otlp/otlptrace` package.
This fix will by default set the status to `Unset` if it is not explicitly set to `Ok` or `Error`. (#2099 #2102)
- The `Inject` method for the `"go.opentelemetry.io/otel/propagation".TraceContext` type no longer injects empty `tracestate` values. (#2108)
- Use `6831` as default Jaeger agent port instead of `6832`. (#2131)
## [Experimental Metrics v0.22.0] - 2021-07-19
### Added
- Adds HTTP support for OTLP metrics exporter. (#2022)
### Removed
- Removed the deprecated package `go.opentelemetry.io/otel/exporters/metric/prometheus`. (#2020)

## Documentation
Each non-example Go Module should have its own `README.md` containing:
- A pkg.go.dev badge which can be generated [here](https://pkg.go.dev/badge/).
- Brief description.
- Installation instructions (and requirements if applicable).
- Hyperlink to an example. Depending on the component the example can be:
- An `example_test.go` like [here](exporters/stdout/stdouttrace/example_test.go).
- A sample Go application with its own `README.md`, like [here](example/zipkin).
- Additional documentation sections such us:
- Configuration,
- Contributing,
- References.
[Here](exporters/jaeger/README.md) is an example of a concise `README.md`.
Moreover, it should be possible to navigate to any `README.md` from the

## Semantic Convention Generation
If a new version of the OpenTelemetry Specification has been released it will be necessary to generate a new
semantic convention package from the YAML definitions in the specification repository. There is a utility in

tagged. Make sure that the specification repo contains a checkout of the the latest tagged release so that the

## Pre-Release
First, decide which module sets will be released and update their versions
in `versions.yaml`. Commit this change to a new branch.
Update go.mod for submodules to depend on the new release which will happen in the next step.
1. Run the pre-release script. It creates a branch `pre_release_<new tag>` that will contain all release changes.
1. Run the `prerelease` make target. It creates a branch
`prerelease_<module set>_<new tag>` that will contain all release changes.
```
./pre_release.sh -t <new tag>
make prerelease MODSET=<module set>
```
2. Verify the changes.
```
git diff main
git diff ...prerelease_<module set>_<new tag>
```
This should have changed the version for all modules to be `<new tag>`.
If these changes look correct, merge them into your pre-release branch:
```go
git merge prerelease_<module set>_<new tag>
```

# OpenTelemetry-Go OTLP Span Exporter
[![Go Reference](https://pkg.go.dev/badge/go.opentelemetry.io/otel/exporters/otlp/otlptrace.svg)](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace)
[OpenTelemetry Protocol Exporter](https://github.com/open-telemetry/opentelemetry-specification/blob/v1.5.0/specification/protocol/exporter.md) implementation.
## Installation
```
go get -u go.opentelemetry.io/otel/exporters/otlp/otlptrace
```
## Examples
- [Exporter setup and examples](./otlptracehttp/example_test.go)
- [Full example sending telemetry to a local collector](../../../example/otel-collector)
## [`otlptrace`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace)
The `otlptrace` package provides an exporter implementing the OTel span exporter interface.
This exporter is configured using a client satisfying the `otlptrace.Client` interface.
This client handles the transformation of data into wire format and the transmission of that data to the collector.
## [`otlptracegrpc`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc)
The `otlptracegrpc` package implements a client for the span exporter that sends trace telemetry data to the collector using gRPC with protobuf-encoded payloads.
## [`otlptracehttp`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp)
The `otlptracehttp` package implements a client for the span exporter that sends trace telemetry data to the collector using HTTP with protobuf-encoded payloads.
## Configuration
### Environment Variables
The following environment variables can be used
(instead of options objects) to override the default configuration.
| Environment variable | Option | Default value |
| ------------------------------------------------------------------------ |------------------------------ | ----------------------------------- |
| `OTEL_EXPORTER_OTLP_ENDPOINT` `OTEL_EXPORTER_OTLP_TRACES_ENDPOINT` | `WithEndpoint` `WithInsecure` | `https://localhost:4317` |
| `OTEL_EXPORTER_OTLP_CERTIFICATE` `OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE` | `WithTLSClientConfig` | |
| `OTEL_EXPORTER_OTLP_HEADERS` `OTEL_EXPORTER_OTLP_TRACES_HEADERS` | `WithHeaders` | |
| `OTEL_EXPORTER_OTLP_COMPRESSION` `OTEL_EXPORTER_OTLP_TRACES_COMPRESSION` | `WithCompression` | |
| `OTEL_EXPORTER_OTLP_TIMEOUT` `OTEL_EXPORTER_OTLP_TRACES_TIMEOUT` | `WithTimeout` | `10s` |
Configuration using options have precedence over the environment variables.

Instruments are categorized as Synchronous or Asynchronous and independently
as Adding or Grouping. 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
Adding 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
Adding 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
Counter: adding, monotonic
UpDownCounter: adding
Histogram: grouping
and the asynchronous instruments are:
SumObserver: additive, monotonic
UpDownSumObserver: additive
ValueObserver: grouping
CounterObserver: adding, monotonic
UpDownCounterObserver: adding
GaugeObserver: grouping
All instruments are provided with support for either float64 or int64 input
values.
