The first is to speak -// the low-level message protocol, reading from a Conn using ReadRequest and -// writing using the various Respond methods. This approach is closest to -// the actual interaction with the kernel and can be the simplest one in contexts -// such as protocol translators. -// -// Servers of synthesized file systems tend to share common -// bookkeeping abstracted away by the second approach, which is to -// call fs.Serve to serve the FUSE protocol using an implementation of -// the service methods in the interfaces FS* (file system), Node* (file -// or directory), and Handle* (opened file or directory). -// There are a daunting number of such methods that can be written, -// but few are required. -// The specific methods are described in the documentation for those interfaces. -// -// The hellofs subdirectory contains a simple illustration of the fs.Serve approach. -// -// Service Methods -// -// The required and optional methods for the FS, Node, and Handle interfaces -// have the general form -// -// Op(ctx context.Context, req *OpRequest, resp *OpResponse) error -// -// where Op is the name of a FUSE operation. Op reads request -// parameters from req and writes results to resp. An operation whose -// only result is the error result omits the resp parameter. -// -// Multiple goroutines may call service methods simultaneously; the -// methods being called are responsible for appropriate -// synchronization. -// -// The operation must not hold on to the request or response, -// including any []byte fields such as WriteRequest.Data or -// SetxattrRequest.Xattr. -// -// Errors -// -// Operations can return errors. The FUSE interface can only -// communicate POSIX errno error numbers to file system clients, the -// message is not visible to file system clients. The returned error -// can implement ErrorNumber to control the errno returned. Without -// ErrorNumber, a generic errno (EIO) is returned. -// -// Error messages will be visible in the debug log as part of the -// response. -// -// Interrupted Operations -// -// In some file systems, some operations -// may take an undetermined amount of time. For example, a Read waiting for -// a network message or a matching Write might wait indefinitely. If the request -// is cancelled and no longer needed, the context will be cancelled. -// Blocking operations should select on a receive from ctx.Done() and attempt to -// abort the operation early if the receive succeeds (meaning the channel is closed). -// To indicate that the operation failed because it was aborted, return fuse.EINTR. -// -// If an operation does not block for an indefinite amount of time, supporting -// cancellation is not necessary. -// -// Authentication -// -// All requests types embed a Header, meaning that the method can -// inspect req.Pid, req.Uid, and req.Gid as necessary to implement -// permission checking.

The error may be fixed by running -`make install` (it will install `glide` if you don't have it): - -```shell -go get -u github.com/uber/jaeger-client-go/ -cd $GOPATH/src/github.com/uber/jaeger-client-go/ -git submodule update --init --recursive -make install -``` - -## Initialization - -See tracer initialization examples in [godoc](https://godoc.org/github.com/uber/jaeger-client-go/config#pkg-examples) -and [config/example_test.go](./config/example_test.go). - -### Environment variables - -The tracer can be initialized with values coming from environment variables. None of the env vars are required -and all of them can be overriden via direct setting of the property on the configuration object. - -Property| Description ---- | --- -JAEGER_SERVICE_NAME | The service name -JAEGER_AGENT_HOST | The hostname for communicating with agent via UDP -JAEGER_AGENT_PORT | The port for communicating with agent via UDP -JAEGER_REPORTER_LOG_SPANS | Whether the reporter should also log the spans -JAEGER_REPORTER_MAX_QUEUE_SIZE | The reporter's maximum queue size -JAEGER_REPORTER_FLUSH_INTERVAL | The reporter's flush interval (ms) -JAEGER_SAMPLER_TYPE | The sampler type -JAEGER_SAMPLER_PARAM | The sampler parameter (number) -JAEGER_SAMPLER_MANAGER_HOST_PORT | The host name and port when using the remote controlled sampler -JAEGER_SAMPLER_MAX_OPERATIONS | The maximum number of operations that the sampler will keep track of -JAEGER_SAMPLER_REFRESH_INTERVAL | How often the remotely controlled sampler will poll jaeger-agent for the appropriate sampling strategy -JAEGER_TAGS | A comma separated list of `name = value` tracer level tags, which get added to all reported spans. The value can also refer to an environment variable using the format `${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 - -### 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 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 115e49ab8a..0000000000 --- a/vendor/github.com/uber/jaeger-client-go/RELEASE.md +++ /dev/null @@ -1,11 +0,0 @@ -# Release Process - -1.
