Here are code snippets +demonstrating some important use cases. + +#### Singleton initialization + +The simplest starting point is `./default_tracer.go`. As early as possible, call + +```go + import "github.com/opentracing/opentracing-go" + import ".../some_tracing_impl" + + func main() { + opentracing.SetGlobalTracer( + // tracing impl specific: + some_tracing_impl.New(...), + ) + ... + } +``` + +#### Non-Singleton initialization + +If you prefer direct control to singletons, manage ownership of the +`opentracing.Tracer` implementation explicitly. + +#### Creating a Span given an existing Go `context.Context` + +If you use `context.Context` in your application, OpenTracing's Go library will +happily rely on it for `Span` propagation. To start a new (blocking child) +`Span`, you can use `StartSpanFromContext`. + +```go + func xyz(ctx context.Context, ...) { + ... + span, ctx := opentracing.StartSpanFromContext(ctx, "operation_name") + defer span.Finish() + span.LogFields( + log.String("event", "soft error"), + log.String("type", "cache timeout"), + log.Int("waited.millis", 1500)) + ... + } +``` + +#### Starting an empty trace by creating a "root span" + +It's always possible to create a "root" `Span` with no parent or other causal +reference. + +```go + func xyz() { + ... + sp := opentracing.StartSpan("operation_name") + defer sp.Finish() + ... + } +``` + +#### Creating a (child) Span given an existing (parent) Span + +```go + func xyz(parentSpan opentracing.Span, ...) { + ... + sp := opentracing.StartSpan( + "operation_name", + opentracing.ChildOf(parentSpan.Context())) + defer sp.Finish() + ... + } +``` + +#### Serializing to the wire + +```go + func makeSomeRequest(ctx context.Context) ... { + if span := opentracing.SpanFromContext(ctx); span != nil { + httpClient := &http.Client{} + httpReq, _ := http.NewRequest("GET", "http://myservice/", nil) + + // Transmit the span's TraceContext as HTTP headers on our + // outbound request. + opentracing.GlobalTracer().Inject( + span.Context(), + opentracing.HTTPHeaders, + opentracing.HTTPHeadersCarrier(httpReq.Header)) + + resp, err := httpClient.Do(httpReq) + ... + } + ... + } +``` + +#### Deserializing from the wire + +```go + http.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) { + var serverSpan opentracing.Span + appSpecificOperationName := ... + wireContext, err := opentracing.GlobalTracer().Extract( + opentracing.HTTPHeaders, + opentracing.HTTPHeadersCarrier(req.Header)) + if err != nil { + // Optionally record something about err here + } + + // Create the span referring to the RPC client if available. + // If wireContext == nil, a root span will be created. + serverSpan = opentracing.StartSpan( + appSpecificOperationName, + ext.RPCServerOption(wireContext)) + + defer serverSpan.Finish() + + ctx := opentracing.ContextWithSpan(context.Background(), serverSpan) + ... + } +``` + +#### Conditionally capture a field using `log.Noop` + +In some situations, you may want to dynamically decide whether or not +to log a field. For example, you may want to capture additional data, +such as a customer ID, in non-production environments: + +```go + func Customer(order *Order) log.Field { + if os.Getenv("ENVIRONMENT") == "dev" { + return log.String("customer", order.Customer.ID) + } + return log.Noop() + } +``` + +#### Goroutine-safety + +The entire public API is goroutine-safe and does not require external +synchronization. + +## API pointers for those implementing a tracing system + +Tracing system implementors may be able to reuse or copy-paste-modify the `basictracer` package, found [here](https://github.com/opentracing/basictracer-go). In particular, see `basictracer.New(...)`. + +## API compatibility + +For the time being, "mild" backwards-incompatible changes may be made without changing the major version number.

None of the env vars are required +and all of them can be overriden 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 +JAEGER_AGENT_PORT | The port for communicating with agent via UDP +JAEGER_ENDPOINT | The HTTP endpoint for sending spans directly to a collector, i.e. http://jaeger-collector:14268/api/traces +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 +JAEGER_REPORTER_MAX_QUEUE_SIZE | The reporter's maximum queue size +JAEGER_REPORTER_FLUSH_INTERVAL | The reporter's flush interval, with units, e.g. "500ms" or "2s" ([valid units][timeunits]) +JAEGER_SAMPLER_TYPE | The sampler type +JAEGER_SAMPLER_PARAM | The sampler parameter (number) +JAEGER_SAMPLER_MANAGER_HOST_PORT | The HTTP endpoint when using the remote sampler, i.e. http://jaeger-agent:5778/sampling +JAEGER_SAMPLER_MAX_OPERATIONS | The maximum number of operations that the sampler will keep track of +JAEGER_SAMPLER_REFRESH_INTERVAL | How often the remotely controlled sampler will poll jaeger-agent for the appropriate sampling strategy, with units, e.g. "1m" or "30s" ([valid units][timeunits]) +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:default}`, where the `:default` is optional, and identifies a value to be used if the environment variable cannot be found +JAEGER_DISABLED | Whether the tracer is disabled or not. If true, the default `opentracing.NoopTracer` is used. +JAEGER_RPC_METRICS | Whether to store RPC metrics + +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.Closer()` 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. + +### 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. + +## 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 diff --git a/vendor/github.com/uber/jaeger-client-go/baggage_setter.go b/vendor/github.com/uber/jaeger-client-go/baggage_setter.go new file mode 100644 index 000000000..1037ca0e8 --- /dev/null +++ b/vendor/github.com/uber/jaeger-client-go/baggage_setter.go @@ -0,0 +1,77 @@ +// Copyright (c) 2017 Uber Technologies, Inc. +// +// Licensed under the Apache License, Version 2.0 (the "License");
