/*
Equal returns true iff protocol buffers a and b are equal.
The arguments must both be pointers to protocol buffer structs.
Equality is defined in this way:
- Two messages are equal iff they are the same type,
corresponding fields are equal, unknown field sets
are equal, and extensions sets are equal.
- Two set scalar fields are equal iff their values are equal.
If the fields are of a floating-point type, remember that
NaN != x for all x, including NaN. If the message is defined
in a proto3 .proto file, fields are not "set"; specifically,
zero length proto3 "bytes" fields are equal (nil == {}).
- Two repeated fields are equal iff their lengths are the same,
and their corresponding elements are equal. Note a "bytes" field,
although represented by []byte, is not a repeated field and the
rule for the scalar fields described above applies.
- Two unset fields are equal.
- Two unknown field sets are equal if their current
encoded state is equal.
- Two extension sets are equal iff they have corresponding
elements that are pairwise equal.
- Two map fields are equal iff their lengths are the same,
and they contain the same set of elements. Zero-length map
fields are equal.
- Every other combination of things are not equal.
The return value is undefined if a and b are not protocol buffers.

/*
Package proto converts data structures to and from the wire format of
protocol buffers. It works in concert with the Go source code generated
for .proto files by the protocol compiler.
A summary of the properties of the protocol buffer interface
for a protocol buffer variable v:
- Names are turned from camel_case to CamelCase for export.
- There are no methods on v to set fields; just treat
them as structure fields.
- There are getters that return a field's value if set,
and return the field's default value if unset.
The getters work even if the receiver is a nil message.
- The zero value for a struct is its correct initialization state.
All desired fields must be set before marshaling.
- A Reset() method will restore a protobuf struct to its zero state.
- Non-repeated fields are pointers to the values; nil means unset.
That is, optional or required field int32 f becomes F *int32.
- Repeated fields are slices.
- Helper functions are available to aid the setting of fields.
msg.Foo = proto.String("hello") // set field
- Constants are defined to hold the default values of all fields that
have them. They have the form Default_StructName_FieldName.
Because the getter methods handle defaulted values,
direct use of these constants should be rare.
- Enums are given type names and maps from names to values.
Enum values are prefixed by the enclosing message's name, or by the
enum's type name if it is a top-level enum. Enum types have a String
method, and a Enum method to assist in message construction.
- Nested messages, groups and enums have type names prefixed with the name of
the surrounding message type.
- Extensions are given descriptor names that start with E_,
followed by an underscore-delimited list of the nested messages
that contain it (if any) followed by the CamelCased name of the
extension field itself. HasExtension, ClearExtension, GetExtension
and SetExtension are functions for manipulating extensions.
- Oneof field sets are given a single field in their message,
with distinguished wrapper types for each possible field value.
- Marshal and Unmarshal are functions to encode and decode the wire format.
When the .proto file specifies `syntax="proto3"`, there are some differences:
- Non-repeated fields of non-message type are values instead of pointers.
- Enum types do not get an Enum method.
The simplest way to describe this is to see an example.
Given file test.proto, containing
package example;
enum FOO { X = 17; }
message Test {
required string label = 1;
optional int32 type = 2 [default=77];
repeated int64 reps = 3;

// 'type.googleapis.com/full.type.name' as the type URL and the unpack
// methods only use the fully qualified type name after the last '/'
// in the type URL, for example "foo.bar.com/x/y.z" will yield type
// name "y.z".
//
//
// JSON
// ====
// The JSON representation of an `Any` value uses the regular
// representation of the deserialized, embedded message, with an
// additional field `@type` which contains the type URL. Example:
//
// package google.profile;
// message Person {
// string first_name = 1;
// string last_name = 2;
// }
//
// {
// "@type": "type.googleapis.com/google.profile.Person",
// "firstName": <string>,
// "lastName": <string>
// }
//
// If the embedded message type is well-known and has a custom JSON
// representation, that representation will be embedded adding a field
// `value` which holds the custom JSON in addition to the `@type`
// field. Example (for message [google.protobuf.Duration][]):
//
// {
// "@type": "type.googleapis.com/google.protobuf.Duration",
// "value": "1.212s"
// }
//
type Any struct {
// A URL/resource name that uniquely identifies the type of the serialized
// protocol buffer message. This string must contain at least
// one "/" character. The last segment of the URL's path must represent
// the fully qualified name of the type (as in
// `path/google.protobuf.Duration`). The name should be in a canonical form
// (e.g., leading "." is not accepted).
//
// In practice, teams usually precompile into the binary all types that they
// expect it to use in the context of Any. However, for URLs which use the
// scheme `http`, `https`, or no scheme, one can optionally set up a type
// server that maps type URLs to message definitions as follows:
//
// * If no scheme is provided, `https` is assumed.
// * An HTTP GET on the URL must yield a [google.protobuf.Type][]
// value in binary format, or produce an error.
// * Applications are allowed to cache lookup results based on the
// URL, or have them precompiled into a binary to avoid any
// lookup. Therefore, binary compatibility needs to be preserved
// on changes to types. (Use versioned type names to manage
// breaking changes.)
//
// Note: this functionality is not currently available in the official
// protobuf release, and it is not used for type URLs beginning with
// type.googleapis.com.
//
// Schemes other than `http`, `https` (or the empty scheme) might be
// used with implementation specific semantics.
//
TypeUrl string `protobuf:"bytes,1,opt,name=type_url,json=typeUrl,proto3" json:"type_url,omitempty"`
// Must be a valid serialized protocol buffer of the above specified type.

// `Any` contains an arbitrary serialized protocol buffer message along with a

// Foo foo = ...;
// Any any;
// any.PackFrom(foo);
// ...
// if (any.UnpackTo(&foo)) {
// ...
// }

//
// Foo foo = ...;
// Any any = Any.pack(foo);
// ...
// if (any.is(Foo.class)) {
// foo = any.unpack(Foo.class);
// }
//
// Example 3: Pack and unpack a message in Python.
//
// foo = Foo(...)
// any = Any()
// any.Pack(foo)
// ...
// if any.Is(Foo.DESCRIPTOR):
// any.Unpack(foo)
// ...
//
// Example 4: Pack and unpack a message in Go
//
// foo := &pb.Foo{...}

// A Duration represents a signed, fixed-length span of time represented
// as a count of seconds and fractions of seconds at nanosecond
// resolution. It is independent of any calendar and concepts like "day"
// or "month". It is related to Timestamp in that the difference between
// two Timestamp values is a Duration and it can be added or subtracted
// from a Timestamp. Range is approximately +-10,000 years.
//
// # Examples
//
// Example 1: Compute Duration from two Timestamps in pseudo code.
//
// Timestamp start = ...;
// Timestamp end = ...;
// Duration duration = ...;
//
// duration.seconds = end.seconds - start.seconds;
// duration.nanos = end.nanos - start.nanos;
//
// if (duration.seconds < 0 && duration.nanos > 0) {
// duration.seconds += 1;
// duration.nanos -= 1000000000;
// } else if (duration.seconds > 0 && duration.nanos < 0) {
// duration.seconds -= 1;
// duration.nanos += 1000000000;
// }
//
// Example 2: Compute Timestamp from Timestamp + Duration in pseudo code.
//
// Timestamp start = ...;
// Duration duration = ...;
// Timestamp end = ...;
//
// end.seconds = start.seconds + duration.seconds;
// end.nanos = start.nanos + duration.nanos;
//
// if (end.nanos < 0) {

// Example 3: Compute Duration from datetime.timedelta in Python.
//
// td = datetime.timedelta(days=3, minutes=10)
// duration = Duration()

//
// In JSON format, the Duration type is encoded as a string rather than an
// object, where the string ends in the suffix "s" (indicating seconds) and
// is preceded by the number of seconds, with nanoseconds expressed as
// fractional seconds. For example, 3 seconds with 0 nanoseconds should be
// encoded in JSON format as "3s", while 3 seconds and 1 nanosecond should
// be expressed in JSON format as "3.000000001s", and 3 seconds and 1
// microsecond should be expressed in JSON format as "3.000001s".

// A Timestamp represents a point in time independent of any time zone or local
// calendar, encoded as a count of seconds and fractions of seconds at
// nanosecond resolution. The count is relative to an epoch at UTC midnight on
// January 1, 1970, in the proleptic Gregorian calendar which extends the
// Gregorian calendar backwards to year one.
//
// All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
// second table is needed for interpretation, using a [24-hour linear
// smear](https://developers.google.com/time/smear).
//
// The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
// restricting to that range, we ensure that we can convert to and from [RFC
// 3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
//
// # Examples
//
// Example 1: Compute Timestamp from POSIX `time()`.
//
// Timestamp timestamp;
// timestamp.set_seconds(time(NULL));
// timestamp.set_nanos(0);
//
// Example 2: Compute Timestamp from POSIX `gettimeofday()`.
//
// struct timeval tv;
// gettimeofday(&tv, NULL);
//
// Timestamp timestamp;
// timestamp.set_seconds(tv.tv_sec);
// timestamp.set_nanos(tv.tv_usec * 1000);
//
// Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
//
// FILETIME ft;
// GetSystemTimeAsFileTime(&ft);
// UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
//
// // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
// // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
// Timestamp timestamp;
// timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
// timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
//
// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
//
// long millis = System.currentTimeMillis();
//
// Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
// .setNanos((int) ((millis % 1000) * 1000000)).build();
//
//
// Example 5: Compute Timestamp from current time in Python.
//
// timestamp = Timestamp()
// timestamp.GetCurrentTime()
//
// # JSON Mapping
//
// In JSON format, the Timestamp type is encoded as a string in the
// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
// where {year} is always expressed using four digits while {month}, {day},
// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
// is required. A proto3 JSON serializer should always use UTC (as indicated by
// "Z") when printing the Timestamp type and a proto3 JSON parser should be
// able to accept both UTC and other timezones (as indicated by an offset).
//
// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
// 01:30 UTC on January 15, 2017.
//
// In JavaScript, one can convert a Date object to this format using the
// standard
// [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
// method. In Python, a standard `datetime.datetime` object can be converted
// to this format using
// [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
// the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
// the Joda Time's [`ISODateTimeFormat.dateTime()`](
// http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D
// ) to obtain a formatter capable of generating timestamps in this format.

// A Timestamp represents a point in time independent of any time zone or local
// calendar, encoded as a count of seconds and fractions of seconds at
// nanosecond resolution. The count is relative to an epoch at UTC midnight on
// January 1, 1970, in the proleptic Gregorian calendar which extends the
// Gregorian calendar backwards to year one.
//
// All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
// second table is needed for interpretation, using a [24-hour linear
// smear](https://developers.google.com/time/smear).
//
// The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
// restricting to that range, we ensure that we can convert to and from [RFC
// 3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
//
// # Examples
//
// Example 1: Compute Timestamp from POSIX `time()`.
//
// Timestamp timestamp;
// timestamp.set_seconds(time(NULL));
// timestamp.set_nanos(0);
//
// Example 2: Compute Timestamp from POSIX `gettimeofday()`.
//
// struct timeval tv;
// gettimeofday(&tv, NULL);
//
// Timestamp timestamp;
// timestamp.set_seconds(tv.tv_sec);
// timestamp.set_nanos(tv.tv_usec * 1000);
//
// Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
//
// FILETIME ft;
// GetSystemTimeAsFileTime(&ft);
// UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
//
// // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
// // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
// Timestamp timestamp;
// timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
// timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
//
// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
//
// long millis = System.currentTimeMillis();
//
// Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
// .setNanos((int) ((millis % 1000) * 1000000)).build();
//
//
// Example 5: Compute Timestamp from current time in Python.
//
// timestamp = Timestamp()
// timestamp.GetCurrentTime()
//
// # JSON Mapping
//
// In JSON format, the Timestamp type is encoded as a string in the
// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
// where {year} is always expressed using four digits while {month}, {day},
// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
// is required. A proto3 JSON serializer should always use UTC (as indicated by
// "Z") when printing the Timestamp type and a proto3 JSON parser should be
// able to accept both UTC and other timezones (as indicated by an offset).
//
// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
// 01:30 UTC on January 15, 2017.
//
// In JavaScript, one can convert a Date object to this format using the
// standard
// [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
// method. In Python, a standard `datetime.datetime` object can be converted
// to this format using
// [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
// the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
// the Joda Time's [`ISODateTimeFormat.dateTime()`](
// http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D
// ) to obtain a formatter capable of generating timestamps in this format.
//
//
message Timestamp {
// Represents seconds of UTC time since Unix epoch
// 1970-01-01T00:00:00Z. Must be from 0001-01-01T00:00:00Z to
// 9999-12-31T23:59:59Z inclusive.

Changes by Version
==================
2.25.0 (2020-07-13)
-------------------
## Breaking changes
- [feat] Periodically re-resolve UDP server address, with opt-out (#520) -- Trevor Foster
The re-resolving of UDP address is now enabled by default, to make the client more robust in Kubernetes deployments.
The old resolve-once behavior can be restored by setting DisableAttemptReconnecting=true in the Configuration struct,
or via JAEGER_REPORTER_ATTEMPT_RECONNECTING_DISABLED=true environment variable.
## Bug fixes
- Do not add invalid context to references (#521) -- Yuri Shkuro

- Support custom HTTP headers when reporting spans over HTTP ([#479](https://github.com/jaegertracing/jaeger-client-go/pull/479)) -- Albert Teoh
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

contributor, have the legal right to make the contribution. See the [DCO](DCO)
file for details.
## Getting Started
This library uses [dep](https://golang.github.io/dep/) to manage dependencies.
To get started, make sure you clone the Git repository into the correct location
`github.com/uber/jaeger-client-go` relative to `$GOPATH`:
```
mkdir -p $GOPATH/src/github.com/uber
cd $GOPATH/src/github.com/uber
git clone git@github.com:jaegertracing/jaeger-client-go.git jaeger-client-go
cd jaeger-client-go
git submodule update --init --recursive
```
Then install dependencies and run the tests:
```
make install
make test
```
## Imports grouping
This projects follows the following pattern for grouping imports in Go files:
* imports from standard library
* imports from other projects
* imports from `jaeger-client-go` project
For example:
```go
import (
"fmt"
"github.com/uber/jaeger-lib/metrics"
"go.uber.org/zap"
"github.com/uber/jaeger-client-go/config"
)
```
## Making A Change
*Before making any significant changes, please [open an
issue](https://github.com/jaegertracing/jaeger-client-go/issues).* Discussing your proposed
changes ahead of time will make the contribution process smooth for everyone.
Once we've discussed your changes and you've got your code ready, make sure
that tests are passing (`make test` or `make cover`) and open your PR. Your
pull request is most likely to be accepted if it:
* Includes tests for new functionality.
* Follows the guidelines in [Effective
Go](https://golang.org/doc/effective_go.html) and the [Go team's common code
review comments](https://github.com/golang/go/wiki/CodeReviewComments).
* Has a [good commit message](https://chris.beams.io/posts/git-commit/):
* Separate subject from body with a blank line
* Limit the subject line to 50 characters
* Capitalize the subject line
* Do not end the subject line with a period
* Use the imperative mood in the subject line
* Wrap the body at 72 characters
* Use the body to explain _what_ and _why_ instead of _how_
* Each commit must be signed by the author ([see below](#sign-your-work)).
## License
By contributing your code, you agree to license your contribution under the terms
of the [Apache License](LICENSE).
If you are adding a new file it should have a header like below. The easiest
way to add such header is to run `make fmt`.
```
// Copyright (c) 2017 The Jaeger Authors.
//
// Licensed under the Apache License, Version 2.0 (the "License");
// you may not use this file except in compliance with the License.
// You may obtain a copy of the License at

// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.

```
## Sign your work
The sign-off is a simple line at the end of the explanation for the
patch, which certifies that you wrote it or otherwise have the right to
pass it on as an open-source patch. The rules are pretty simple: if you
can certify the below (from
[developercertificate.org](http://developercertificate.org/)):
```
Developer Certificate of Origin
Version 1.1
Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
660 York Street, Suite 102,
San Francisco, CA 94110 USA
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license
indicated in the file; or
(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified
it.
(d) I understand and agree that this project and the contribution
are public and that a record of the contribution (including all
personal information I submit with it, including my sign-off) is
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
```
then you just add a line to every git commit message:
Signed-off-by: Joe Smith <joe@gmail.com>
using your real name (sorry, no pseudonyms or anonymous contributions.)
You can add the sign off when creating the git commit via `git commit -s`.
If you want this to be automatic you can set up some aliases:
```
git config --add alias.amend "commit -s --amend"
git config --add alias.c "commit -s"
```

# Jaeger Bindings for Go OpenTracing API
Instrumentation library that implements an
[OpenTracing Go](https://github.com/opentracing/opentracing-go) Tracer for Jaeger (https://jaegertracing.io).
**IMPORTANT**: The library's import path is based on its original location under `github.com/uber`. Do not try to import it as `github.com/jaegertracing`, it will not compile. We might revisit this in the next major release.
* :white_check_mark: `import "github.com/uber/jaeger-client-go"`
* :x: `import "github.com/jaegertracing/jaeger-client-go"`
## How to Contribute
Please see [CONTRIBUTING.md](CONTRIBUTING.md).
## Installation
We recommended using a dependency manager like [dep](https://golang.github.io/dep/)
and [semantic versioning](http://semver.org/) when including this library into an application.
For example, Jaeger backend imports this library like this:
```toml
[[constraint]]
name = "github.com/uber/jaeger-client-go"
version = "2.17"
```
If you instead want to use the latest version in `master`, you can pull it via `go get`.
Note that during `go get` you may see build errors due to incompatible dependencies, which is why
we recommend using semantic versions for dependencies. 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()
```
