- -2.20.1 (2019-11-08) -------------------- - -Minor patch via https://github.com/jaegertracing/jaeger-client-go/pull/468 - -- Make `AdaptiveSamplerUpdater` usable with default values; Resolves #467 -- Create `OperationNameLateBinding` sampler option and config option -- Make `SamplerOptions` var of public type, so that its functions are discoverable via godoc - - -2.20.0 (2019-11-06) -------------------- - -## New Features - -- Allow all in-process spans of a trace to share sampling state (#443) -- Prithvi Raj - - Sampling state is shared between all spans of the trace that are still in memory. - This allows implementation of delayed sampling decisions (see below). - -- Support delayed sampling decisions (#449) -- Yuri Shkuro - - This is a large structural change to how the samplers work. - It allows some samplers to be executed multiple times on different - span events (like setting a tag) and make a positive sampling decision - later in the span life cycle, or even based on children spans. - See [README](./README.md#delayed-sampling) for more details. - - There is a related minor change in behavior of the adaptive (per-operation) sampler, - which will no longer re-sample the trace when `span.SetOperation()` is called, i.e. the - operation used to make the sampling decision is always the one provided at span creation. - -- Add experimental tag matching sampler (#452) -- Yuri Shkuro - - A sampler that can sample a trace based on a certain tag added to the root - span or one of its local (in-process) children. The sampler can be used with - another experimental `PrioritySampler` that allows multiple samplers to try - to make a sampling decision, in a certain priority order. - -- [log/zap] Report whether a trace was sampled (#445) -- Abhinav Gupta -- Allow config.FromEnv() to enrich an existing config object (#436) -- Vineeth Reddy - -## Minor patches - -- Expose Sampler on Tracer and accept sampler options via Configuration (#460) -- Yuri Shkuro -- Fix github.com/uber-go/atomic import (#464) -- Yuri Shkuro -- Add nodejs to crossdock tests (#441) -- Bhavin Gandhi -- Bump Go compiler version to 1.13 (#453) -- Yuri Shkuro - -2.19.0 (2019-09-23) -------------------- - -- Upgrade jaeger-lib to 2.2 and unpin Prom client (#434) -- Yuri Shkuro - - -2.18.1 (2019-09-16) -------------------- - -- Remove go.mod / go.sum that interfere with `go get` (#432) - - -2.18.0 (2019-09-09) -------------------- - -- Add option "noDebugFlagOnForcedSampling" for tracer initialization [resolves #422] (#423) <Jun Guo> - - -2.17.0 (2019-08-30) -------------------- - -- Add a flag for firehose mode (#419) <Prithvi Raj> -- Default sampling server URL to agent (#414) <Bryan Boreham> -- Update default sampling rate when sampling strategy is refreshed (#413) <Bryan Boreham> -- Support "Self" Span Reference (#411) <dm03514> -- Don't complain about blank service name if tracing is Disabled (#410) Yuri <Shkuro> -- Use IP address from tag if exist (#402) <NikoKVCS> -- Expose span data to custom reporters [fixes #394] (#399) <Curtis Allen> -- Fix the span allocation in the pool (#381) <Dmitry Ponomarev> - - -2.16.0 (2019-03-24) -------------------- - -- Add baggage to B3 codec (#319) <Pavol Loffay> -- Add support for 128bit trace ids to zipkin thrift spans.

The error may be fixed by running -`make install` (it will install `dep` if you don't have it): - -```shell -go get -u github.com/uber/jaeger-client-go/ -cd $GOPATH/src/github.com/uber/jaeger-client-go/ -git submodule update --init --recursive -make install -``` - -## Initialization - -See tracer initialization examples in [godoc](https://godoc.org/github.com/uber/jaeger-client-go/config#pkg-examples) -and [config/example_test.go](./config/example_test.go). - -### Environment variables - -The tracer can be initialized with values coming from environment variables, if it is -[built from a config](https://pkg.go.dev/github.com/uber/jaeger-client-go/config?tab=doc#Configuration.NewTracer) -that was created via [FromEnv()](https://pkg.go.dev/github.com/uber/jaeger-client-go/config?tab=doc#FromEnv). -None of the env vars are required and all of them can be overridden via direct setting -of the property on the configuration object. - -Property| Description ---- | --- -JAEGER_SERVICE_NAME | The service name. -JAEGER_AGENT_HOST | The hostname for communicating with agent via UDP (default `localhost`). -JAEGER_AGENT_PORT | The port for communicating with agent via UDP (default `6831`). -JAEGER_ENDPOINT | The HTTP endpoint for sending spans directly to a collector, i.e. http://jaeger-collector:14268/api/traces. If specified, the agent host/port are ignored. -JAEGER_USER | Username to send as part of "Basic" authentication to the collector endpoint. -JAEGER_PASSWORD | Password to send as part of "Basic" authentication to the collector endpoint. -JAEGER_REPORTER_LOG_SPANS | Whether the reporter should also log the spans" `true` or `false` (default `false`). -JAEGER_REPORTER_MAX_QUEUE_SIZE | The reporter's maximum queue size (default `100`). -JAEGER_REPORTER_FLUSH_INTERVAL | The reporter's flush interval, with units, e.g. `500ms` or `2s` ([valid units][timeunits]; default `1s`). -JAEGER_REPORTER_ATTEMPT_RECONNECTING_DISABLED | When true, disables udp connection helper that periodically re-resolves the agent's hostname and reconnects if there was a change (default `false`). -JAEGER_REPORTER_ATTEMPT_RECONNECT_INTERVAL | Controls how often the agent client re-resolves the provided hostname in order to detect address changes ([valid units][timeunits]; default `30s`). -JAEGER_SAMPLER_TYPE | The sampler type: `remote`, `const`, `probabilistic`, `ratelimiting` (default `remote`). See also https://www.jaegertracing.io/docs/latest/sampling/. -JAEGER_SAMPLER_PARAM | The sampler parameter (number). -JAEGER_SAMPLER_MANAGER_HOST_PORT | (deprecated) The HTTP endpoint when using the `remote` sampler. -JAEGER_SAMPLING_ENDPOINT | The URL for the sampling configuration server when using sampler type `remote` (default `http://127.0.0.1:5778/sampling`). -JAEGER_SAMPLER_MAX_OPERATIONS | The maximum number of operations that the sampler will keep track of (default `2000`). -JAEGER_SAMPLER_REFRESH_INTERVAL | How often the `remote` sampler should poll the configuration server for the appropriate sampling strategy, e.g. "1m" or "30s" ([valid units][timeunits]; default `1m`). -JAEGER_TAGS | A comma separated list of `name=value` tracer-level tags, which get added to all reported spans. The value can also refer to an environment variable using the format `${envVarName:defaultValue}`. -JAEGER_DISABLED | Whether the tracer is disabled or not. If `true`, the `opentracing.NoopTracer` is used (default `false`). -JAEGER_RPC_METRICS | Whether to store RPC metrics, `true` or `false` (default `false`). - -By default, the client sends traces via UDP to the agent at `localhost:6831`. Use `JAEGER_AGENT_HOST` and -`JAEGER_AGENT_PORT` to send UDP traces to a different `host:port`. If `JAEGER_ENDPOINT` is set, the client sends traces -to the endpoint via `HTTP`, making the `JAEGER_AGENT_HOST` and `JAEGER_AGENT_PORT` unused. If `JAEGER_ENDPOINT` is -secured, HTTP basic authentication can be performed by setting the `JAEGER_USER` and `JAEGER_PASSWORD` environment -variables. - -### Closing the tracer via `io.Closer` - -The constructor function for Jaeger Tracer returns the tracer itself and an `io.Closer` instance. -It is recommended to structure your `main()` so that it calls the `Close()` function on the closer -before exiting, e.g. - -```go -tracer, closer, err := cfg.NewTracer(...) -defer closer.Close() -``` - -This is especially useful for command-line tools that enable tracing, as well as -for the long-running apps that support graceful shutdown. For example, if your deployment -system sends SIGTERM instead of killing the process and you trap that signal to do a graceful -exit, then having `defer closer.Close()` ensures that all buffered spans are flushed. - -### Metrics & Monitoring - -The tracer emits a number of different metrics, defined in -[metrics.go](metrics.go). The monitoring backend is expected to support -tag-based metric names, e.g. instead of `statsd`-style string names -like `counters.my-service.jaeger.spans.started.sampled`, the metrics -are defined by a short name and a collection of key/value tags, for -example: `name:jaeger.traces, state:started, sampled:y`. See [metrics.go](./metrics.go) -file for the full list and descriptions of emitted metrics. - -The monitoring backend is represented by the `metrics.Factory` interface from package -[`"github.com/uber/jaeger-lib/metrics"`](https://github.com/jaegertracing/jaeger-lib/tree/master/metrics). An implementation -of that interface can be passed as an option to either the Configuration object or the Tracer -constructor, for example: - -```go -import ( - "github.com/uber/jaeger-client-go/config" - "github.com/uber/jaeger-lib/metrics/prometheus" -) - - metricsFactory := prometheus.New() - tracer, closer, err := config.Configuration{ - ServiceName: "your-service-name", - }.NewTracer( - config.Metrics(metricsFactory), - ) -``` - -By default, a no-op `metrics.NullFactory` is used. - -### Logging - -The tracer can be configured with an optional logger, which will be -used to log communication errors, or log spans if a logging reporter -option is specified in the configuration. The logging API is abstracted -by the [Logger](logger.go) interface. A logger instance implementing -this interface can be set on the `Config` object before calling the -`New` method. - -Besides the [zap](https://github.com/uber-go/zap) implementation -bundled with this package there is also a [go-kit](https://github.com/go-kit/kit) -one in the [jaeger-lib](https://github.com/jaegertracing/jaeger-lib) repository. - -## Instrumentation for Tracing - -Since this tracer is fully compliant with OpenTracing API 1.0, -all code instrumentation should only use the API itself, as described -in the [opentracing-go](https://github.com/opentracing/opentracing-go) documentation. - -## Features - -### Reporters - -A "reporter" is a component that receives the finished spans and reports -them to somewhere. Under normal circumstances, the Tracer -should use the default `RemoteReporter`, which sends the spans out of -process via configurable "transport". For testing purposes, one can -use an `InMemoryReporter` that accumulates spans in a buffer and -allows to retrieve them for later verification. Also available are -`NullReporter`, a no-op reporter that does nothing, a `LoggingReporter` -which logs all finished spans using their `String()` method, and a -`CompositeReporter` that can be used to combine more than one reporter -into one, e.g. to attach a logging reporter to the main remote reporter. - -### Span Reporting Transports - -The remote reporter uses "transports" to actually send the spans out -of process. Currently the supported transports include: - * [Jaeger Thrift](https://github.com/jaegertracing/jaeger-idl/blob/master/thrift/agent.thrift) over UDP or HTTP, - * [Zipkin Thrift](https://github.com/jaegertracing/jaeger-idl/blob/master/thrift/zipkincore.thrift) over HTTP. - -### Sampling - -The tracer does not record all spans, but only those that have the -sampling bit set in the `flags`. When a new trace is started and a new -unique ID is generated, a sampling decision is made whether this trace -should be sampled. The sampling decision is propagated to all downstream -calls via the `flags` field of the trace context. The following samplers -are available: - 1. `RemotelyControlledSampler` uses one of the other simpler samplers - and periodically updates it by polling an external server. This - allows dynamic control of the sampling strategies. - 1. `ConstSampler` always makes the same sampling decision for all - trace IDs. it can be configured to either sample all traces, or - to sample none. - 1. `ProbabilisticSampler` uses a fixed sampling rate as a probability - for a given trace to be sampled. The actual decision is made by - comparing the trace ID with a random number multiplied by the - sampling rate. - 1. `RateLimitingSampler` can be used to allow only a certain fixed - number of traces to be sampled per second. - -#### Delayed sampling - -Version 2.20 introduced the ability to delay sampling decisions in the life cycle -of the root span. It involves several features and architectural changes: - * **Shared sampling state**: the sampling state is shared across all local - (i.e. in-process) spans for a given trace. - * **New `SamplerV2` API** allows the sampler to be called at multiple points - in the life cycle of a span: - * on span creation - * on overwriting span operation name - * on setting span tags - * on finishing the span - * **Final/non-final sampling state**: the new `SamplerV2` API allows the sampler - to indicate if the negative sampling decision is final or not (positive sampling - decisions are always final). If the decision is not final, the sampler will be - called again on further span life cycle events, like setting tags. - -These new features are used in the experimental `x.TagMatchingSampler`, which -can sample a trace based on a certain tag added to the root -span or one of its local (in-process) children. The sampler can be used with -another experimental `x.PrioritySampler` that allows multiple samplers to try -to make a sampling decision, in a certain priority order. - -### Baggage Injection - -The OpenTracing spec allows for [baggage][baggage], which are key value pairs that are added -to the span context and propagated throughout the trace. An external process can inject baggage -by setting the special HTTP Header `jaeger-baggage` on a request: - -```sh -curl -H "jaeger-baggage: key1=value1, key2=value2" http://myhost.com -``` - -Baggage can also be programatically set inside your service: - -```go -if span := opentracing.SpanFromContext(ctx); span != nil { - span.SetBaggageItem("key", "value") -} -``` - -Another service downstream of that can retrieve the baggage in a similar way: - -```go -if span := opentracing.SpanFromContext(ctx); span != nil { - val := span.BaggageItem("key") - println(val) -} -``` - -### Debug Traces (Forced Sampling) - -#### Programmatically - -The OpenTracing API defines a `sampling.priority` standard tag that -can be used to affect the sampling of a span and its children: - -```go -import ( - "github.com/opentracing/opentracing-go" - "github.com/opentracing/opentracing-go/ext" -) - -span := opentracing.SpanFromContext(ctx) -ext.SamplingPriority.Set(span, 1) -``` - -#### Via HTTP Headers - -Jaeger Tracer also understands a special HTTP Header `jaeger-debug-id`, -which can be set in the incoming request, e.g. - -```sh -curl -H "jaeger-debug-id: some-correlation-id" http://myhost.com -``` - -When Jaeger sees this header in the request that otherwise has no -tracing context, it ensures that the new trace started for this -request will be sampled in the "debug" mode (meaning it should survive -all downsampling that might happen in the collection pipeline), and the -root span will have a tag as if this statement was executed: - -```go -span.SetTag("jaeger-debug-id", "some-correlation-id") -``` - -This allows using Jaeger UI to find the trace by this tag. - -### Zipkin HTTP B3 compatible header propagation - -Jaeger Tracer supports Zipkin B3 Propagation HTTP headers, which are used -by a lot of Zipkin tracers. This means that you can use Jaeger in conjunction with e.g. [these OpenZipkin tracers](https://github.com/openzipkin). - -However it is not the default propagation format, see [here](zipkin/README.md#NewZipkinB3HTTPHeaderPropagator) how to set it up. - -## SelfRef - -Jaeger Tracer supports an additional [span reference][] type call `Self`, which was proposed -to the OpenTracing Specification (https://github.com/opentracing/specification/issues/81) -but not yet accepted. This allows the caller to provide an already created `SpanContext` -when starting a new span. The `Self` reference bypasses trace and span id generation, -as well as sampling decisions (i.e. the sampling bit in the `SpanContext.flags` must be -set appropriately by the caller). - -The `Self` reference supports the following use cases: - * the ability to provide externally generated trace and span IDs - * appending data to the same span from different processes, such as loading and continuing spans/traces from offline (ie log-based) storage - -Usage requires passing in a `SpanContext` and the `jaeger.Self` reference type: -``` -span := tracer.StartSpan( - "continued_span", - jaeger.SelfRef(yourSpanContext), -) -... -defer span.Finish() -``` - -## License - -[Apache 2.0 License](LICENSE). - - -[doc-img]: https://godoc.org/github.com/uber/jaeger-client-go?status.svg -[doc]: https://godoc.org/github.com/uber/jaeger-client-go -[ci-img]: https://travis-ci.org/jaegertracing/jaeger-client-go.svg?branch=master -[ci]: https://travis-ci.org/jaegertracing/jaeger-client-go -[cov-img]: https://codecov.io/gh/jaegertracing/jaeger-client-go/branch/master/graph/badge.svg -[cov]: https://codecov.io/gh/jaegertracing/jaeger-client-go -[ot-img]: https://img.shields.io/badge/OpenTracing--1.0-enabled-blue.svg -[ot-url]: http://opentracing.io -[baggage]: https://github.com/opentracing/specification/blob/master/specification.md#set-a-baggage-item -[timeunits]: https://golang.org/pkg/time/#ParseDuration -[span reference]: https://github.com/opentracing/specification/blob/1.1/specification.md#references-between-spans diff --git a/vendor/github.com/uber/jaeger-client-go/RELEASE.md b/vendor/github.com/uber/jaeger-client-go/RELEASE.md deleted file mode 100644 index 12438d841..000000000 --- a/vendor/github.com/uber/jaeger-client-go/RELEASE.md +++ /dev/null @@ -1,12 +0,0 @@ -# Release Process - -1.
