  • 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 encoding 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 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

  • 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 feat(diag-logger): introduce a new global level api.diag for internal diagnostic logging

PR-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 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.

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

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

import { diag } from "@opentelemetry/api";
diag.setLogger();

PR-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
//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 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 removed public attributes keepAlive and httpAgentOptions from Node.js CollectorTraceExporter and CollectorMetricExporter

0.14.0 to 0.15.0

PR-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 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 Use new gRPC default port

  • The default port used by @opentelemetry/exporter-collector-grpc is changed from 55680 to 4317

PR-1749 chore: improve naming of span related context APIs

  • Rename [gs]etActiveSpan() to [gs]etSpan()
  • Rename setExtractedSpanContext() to setSpanContext()
  • Rename getParentSpanContext() to getSpanContext()
