|
||
Metric and trace exporters are split into separate packages: | ||

|
||
## 0.24.x to 0.25.x | ||
|
||
- SDKs packages for trace and metrics has been renamed to have a consistent naming schema: | ||
- @opentelemetry/tracing -> @opentelemetry/sdk-trace-base | ||
- @opentelemetry/node -> @opentelemetry/sdk-trace-node | ||
- @opentelemetry/web -> @opentelemetry/sdk-trace-web | ||
- @opentelemetry/metrics -> @opentelemetry/sdk-metrics-base | ||
- @opentelemetry/node-sdk -> @opentelemetry/sdk-node | ||
|
||
## 0.23.x to 0.24.x | ||
|
||
- `ResourceAttributes` renamed to `SemanticResourceAttributes` in the `@opentelemetry/semantic-conventions` package | ||
|
||
## 0.19.x to 0.20.0 | ||
|
||
- `HttpBaggage` renamed to `HttpBaggagePropagator` | ||
|
||
- `HttpTraceContext` renamed to `HttpTraceContextPropagator` | ||
|
||
- `JaegerHttpTracePropagator` renamed to `JaegerPropagator` | ||
|
||
- `serviceName` configuration removed from Collector exporters. Use `service.name` Resource attribute instead. | ||
|
||
- Prometheus exporter added suffix `_total` to counter metrics. | ||
|
||
## 0.18.x to 0.19.0 | ||
|
||
- API is now a peer dependency. This means that users will need to include `@opentelemetry/api` as a dependency of their project in order to use the SDK. NPM version 7+ (Node 15+) should do this automatically. | ||
|
||
- All plugins have been removed in favor of instrumentations. | ||
|
||
- The `@opentelemetry/propagator-b3` package previously exported three propagators: `B3Propagator`,`B3SinglePropagator`, and `B3MultiPropagator`, but now only exports the `B3Propagator`. It extracts b3 context in single and multi-header encodings, and injects context using the single-header encoding by default, but can be configured to inject context using the multi-header endcoding during construction: `new B3Propagator({ injectEncoding: B3InjectEncoding.MULTI_HEADER })`. If you were previously using the `B3SinglePropagator` or `B3MultiPropagator` directly, you should update your code to use the `B3Propagator` with the appropriate configuration. See the [readme][otel-propagator-b3] for full details and usage. | ||
|
||
- Sampling configuration via environment variable has changed. If you were using `OTEL_SAMPLING_PROBABILITY` then you should replace it with `OTEL_TRACES_SAMPLER=parentbased_traceidratio` and `OTEL_TRACES_SAMPLER_ARG=<number>` where `<number>` is a number in the [0..1] range, e.g. "0.25". Default is 1.0 if unset. | ||
|
||
## 0.17.0 to 0.18.0 | ||
|
||
- `diag.setLogLevel` is removed and LogLevel can be set by an optional second parameter to `setLogger` | ||
|
||
[PR-1975](https://github.com/open-telemetry/opentelemetry-js/pull/1975) | ||
|
||
- Breaking change - The resulting resource MUST have all attributes that are on any of the two input resources. If a key exists on both the old and updating resource, the value of the updating resource MUST be picked - previously it was opposite. | ||
|
||
## 0.16.0 to 0.17.0 | ||
|
||
[PR-1880](https://github.com/open-telemetry/opentelemetry-js/pull/1880) feat(diag-logger): introduce a new global level api.diag for internal diagnostic logging | ||
|
||
[PR-1925](https://github.com/open-telemetry/opentelemetry-js/pull/1925) feat(diag-logger): part 2 - breaking changes - remove api.Logger, api.NoopLogger, core.LogLevel, core.ConsoleLogger | ||
|
||
- These PR's remove the previous `Logger` and `LogLevel` implementations and change the way you should use the replacement `DiagLogger` and `DiagLogLevel`, below are simple examples of how to change your existing usages. | ||
|
||
### Setting the global diagnostic logger | ||
|
||
The new global [`api.diag`](https://github.com/open-telemetry/opentelemetry-js/blob/main/api/src/api/diag.ts) provides the ability to set the global diagnostic logger `setLogger()` and logging level `setLogLevel()`, it is also a `DiagLogger` implementation and should be directly to log diagnostic messages. | ||
|
||
All included logger references have been removed in preference to using the global `api.diag` directly, so you no longer need to pass around the logger instance via function parameters or included as part of the configuration for a component. | ||
|
||
```javascript | ||
import { diag, DiagConsoleLogger, DiagLogLevel } from "@opentelemetry/api"; | ||
// Setting the default Global logger to use the Console | ||
// And optionally change the logging level (Defaults to INFO) | ||
diag.setLogger(new DiagConsoleLogger(), DiagLogLevel.ERROR) | ||
``` | ||
|
||
### Using the logger anywhere in the code | ||
|
||
```typescript | ||
import { diag } from "@opentelemetry/api"; | ||
|
||
// Remove or make optional the parameter and don't use it. | ||
export function MyFunction() { | ||
diag.debug("..."); | ||
diag.info("..."); | ||
diag.warn("..."); | ||
diag.error("..."); | ||
diag.verbose(".."); | ||
} | ||
|
||
``` | ||
|
||
### Setting the logger back to a noop | ||
|
||
```typescript | ||
import { diag } from "@opentelemetry/api"; | ||
diag.setLogger(); | ||
|
||
``` | ||
|
||
[PR-1855](https://github.com/open-telemetry/opentelemetry-js/pull/1855) Use instrumentation loader to load plugins and instrumentations | ||
|
||
- Providers do no load the plugins anymore. Also PluginLoader has been removed from providers, use `registerInstrumentations` instead | ||
|
||
```javascript | ||
//Previously in node | ||
const provider = new NodeTracerProvider({ | ||
plugins: { | ||
'@grpc/grpc-js': { | ||
enabled: true, | ||
path: '@opentelemetry/plugin-grpc-js', | ||
}, | ||
} | ||
}); | ||
|
||
// Now | ||
const provider = new NodeTracerProvider(); | ||
const { registerInstrumentations } = require('@opentelemetry/instrumentation'); | ||
registerInstrumentations({ | ||
instrumentations: [ | ||
{ | ||
plugins: { | ||
'@grpc/grpc-js': { | ||
enabled: true, | ||
path: '@opentelemetry/plugin-grpc-js', | ||
}, | ||
} | ||
} | ||
], | ||
tracerProvider: provider, | ||
}); | ||
|
||
// or if you want to load only default instrumentations / plugins | ||
registerInstrumentations({ | ||
tracerProvider: provider, | ||
}); | ||
|
||
//Previously in browser | ||
const provider = new WebTracerProvider({ | ||
plugins: [ | ||
new DocumentLoad() | ||
] | ||
}); | ||
// Now | ||
const { registerInstrumentations } = require('@opentelemetry/instrumentation'); | ||
const provider = new WebTracerProvider(); | ||
registerInstrumentations({ | ||
instrumentations: [ | ||
new DocumentLoad(), | ||
], | ||
}); | ||
``` | ||
|
||
- `registerInstrumentations` supports loading old plugins and instrumentations together. It also supports setting tracer provider and meter provider on instrumentations | ||
|
||
[PR-1874](https://github.com/open-telemetry/opentelemetry-js/pull/1874) More specific API type names | ||
|
||
Some types exported from `"@opentelemetry/api"` have been changed to be more specific. | ||
|
||
- `AttributeValue` renamed to `SpanAttributeValue` | ||
- `Attributes` renamed to `SpanAttributes` | ||
- `EntryTtl` renamed to `BaggageEntryTtl` | ||
- `EntryValue` renamed to `BaggageEntryValue` | ||
- `Status` renamed to `SpanStatus` | ||
- `StatusCode` renamed to `SpanStatusCode` | ||
|
||
## 0.15.0 to 0.16.0 | ||
|
||
[PR-1863](https://github.com/open-telemetry/opentelemetry-js/pull/1863) removed public attributes `keepAlive` and `httpAgentOptions` from nodejs `CollectorTraceExporter` and `CollectorMetricExporter` | ||
|
||
## 0.14.0 to 0.15.0 | ||
|
||
[PR-1764](https://github.com/open-telemetry/opentelemetry-js/pull/1764) removed some APIs from `Tracer`: | ||
|
||
- `Tracer.getCurrentSpan()`: use `api.getSpan(api.context.active())` | ||
- `Tracer.withSpan(span)`: use `api.context.with(api.setSpan(api.context.active(), span))` | ||
- `Tracer.bind(target)`: use `api.context.bind(target)` | ||
|
||
[PR-1797](https://github.com/open-telemetry/opentelemetry-js/pull/1797) chore!: split metrics into its own api package: | ||
|
||
- Any references to `require("@opentelemetry/api").metrics` will need to be changed to `require("@opentelemetry/api-metrics").metrics` | ||
|
||
[PR-1725](https://github.com/open-telemetry/opentelemetry-js/pull/1725) Use new gRPC default port | ||
|
||
- The default port used by `@opentelemetry/exporter-collector-grpc` is changed from `55680` to `4317` | ||
|
||
[PR-1749](https://github.com/open-telemetry/opentelemetry-js/pull/1749) chore: improve naming of span related context APIs | ||
|
||
- Rename `[gs]etActiveSpan()` to `[gs]etSpan()` | ||
- Rename `setExtractedSpanContext()` to `setSpanContext()` | ||
- Rename `getParentSpanContext()` to `getSpanContext()` |
