incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.

and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this

# OpenCensus Agent Go Exporter
[![Build Status][travis-image]][travis-url] [![GoDoc][godoc-image]][godoc-url]
This repository contains the Go implementation of the OpenCensus Agent (OC-Agent) Exporter.
OC-Agent is a deamon process running in a VM that can retrieve spans/stats/metrics from
OpenCensus Library, export them to other backends and possibly push configurations back to
Library. See more details on [OC-Agent Readme][OCAgentReadme].
Note: This is an experimental repository and is likely to get backwards-incompatible changes.
Ultimately we may want to move the OC-Agent Go Exporter to [OpenCensus Go core library][OpenCensusGo].
## Installation
```bash
$ go get -u contrib.go.opencensus.io/exporter/ocagent
```
## Usage
```go
import (
"context"
"fmt"
"log"
"time"
"contrib.go.opencensus.io/exporter/ocagent"
"go.opencensus.io/trace"
)
func Example() {
exp, err := ocagent.NewExporter(ocagent.WithInsecure(), ocagent.WithServiceName("your-service-name"))
if err != nil {
log.Fatalf("Failed to create the agent exporter: %v", err)
}
defer exp.Stop()
// Now register it as a trace exporter.
trace.RegisterExporter(exp)
// Then use the OpenCensus tracing library, like we normally would.
ctx, span := trace.StartSpan(context.Background(), "AgentExporter-Example")
defer span.End()
for i := 0; i < 10; i++ {
_, iSpan := trace.StartSpan(ctx, fmt.Sprintf("Sample-%d", i))
<-time.After(6 * time.Millisecond)

Name *string `protobuf:"bytes,1,opt,name=name" json:"name,omitempty"`
// If non-empty, indicates that the named file should already exist, and the
// content here is to be inserted into that file at a defined insertion
// point. This feature allows a code generator to extend the output
// produced by another code generator. The original generator may provide
// insertion points by placing special annotations in the file that look
// like:
// @@protoc_insertion_point(NAME)
// The annotation can have arbitrary text before and after it on the line,
// which allows it to be placed in a comment. NAME should be replaced with
// an identifier naming the point -- this is what other generators will use
// as the insertion_point. Code inserted at this point will be placed
// immediately above the line containing the insertion point (thus multiple
// insertions to the same point will come out in the order they were added).
// The double-@ is intended to make it unlikely that the generated code
// could contain things that look like insertion points by accident.
//
// For example, the C++ code generator places the following line in the
// .pb.h files that it generates:
// // @@protoc_insertion_point(namespace_scope)
// This line appears within the scope of the file's package namespace, but
// outside of any particular class. Another plugin can then specify the
// insertion_point "namespace_scope" to generate additional classes or
// other declarations that should be placed in this scope.
//
// Note that if the line containing the insertion point begins with
// whitespace, the same whitespace will be added to every line of the
// inserted text. This is useful for languages like Python, where
// indentation matters. In these languages, the insertion point comment
// should be indented the same amount as any inserted code will need to be
// in order to work correctly in that context.
//
// The code generator that generates the initial file and the one which
// inserts into it must both run as part of a single invocation of protoc.
// Code generators are executed in the order in which they appear on the
// command line.
//
// If |insertion_point| is present, |name| must also be present.

// protoc (aka the Protocol Compiler) can be extended via plugins. A plugin is
// just a program that reads a CodeGeneratorRequest from stdin and writes a
// CodeGeneratorResponse to stdout.
//
// Plugins written using C++ can use google/protobuf/compiler/plugin.h instead
// of dealing with the raw protocol defined here.
//
// A plugin executable needs only to be placed somewhere in the path. The
// plugin should be named "protoc-gen-$NAME", and will then be used when the
// flag "--${NAME}_out" is passed to protoc.

// protobuf wire format. This theoretically could allow a plugin to stream
// in the FileDescriptorProtos and handle them one by one rather than read
// the entire set into memory at once. However, as of this writing, this
// is not similarly optimized on protoc's end -- it will store all fields in

//
// This should be used to indicate errors in .proto files which prevent the
// code generator from generating correct code. Errors which indicate a
// problem in protoc itself -- such as the input CodeGeneratorRequest being
// unparseable -- should be reported by writing a message to stderr and
// exiting with a non-zero status code.

// Represents a single generated file.
message File {
// The file name, relative to the output directory. The name must not
// contain "." or ".." components and must be relative, not be absolute (so,
// the file cannot lie outside the output directory). "/" must be used as
// the path separator, not "\".
//
// If the name is omitted, the content will be appended to the previous
// file. This allows the generator to break large files into small chunks,
// and allows the generated text to be streamed back to protoc so that large
// files need not reside completely in memory at one time. Note that as of
// this writing protoc does not optimize for this -- it will read the entire
// CodeGeneratorResponse before writing files to disk.
optional string name = 1;
// If non-empty, indicates that the named file should already exist, and the
// content here is to be inserted into that file at a defined insertion
// point. This feature allows a code generator to extend the output
// produced by another code generator. The original generator may provide
// insertion points by placing special annotations in the file that look
// like:
// @@protoc_insertion_point(NAME)
// The annotation can have arbitrary text before and after it on the line,
// which allows it to be placed in a comment. NAME should be replaced with
// an identifier naming the point -- this is what other generators will use
// as the insertion_point. Code inserted at this point will be placed
// immediately above the line containing the insertion point (thus multiple
// insertions to the same point will come out in the order they were added).
// The double-@ is intended to make it unlikely that the generated code
// could contain things that look like insertion points by accident.
//
// For example, the C++ code generator places the following line in the
// .pb.h files that it generates:
// // @@protoc_insertion_point(namespace_scope)
// This line appears within the scope of the file's package namespace, but
// outside of any particular class. Another plugin can then specify the
// insertion_point "namespace_scope" to generate additional classes or
// other declarations that should be placed in this scope.
//
// Note that if the line containing the insertion point begins with
// whitespace, the same whitespace will be added to every line of the
// inserted text. This is useful for languages like Python, where
// indentation matters. In these languages, the insertion point comment
// should be indented the same amount as any inserted code will need to be
// in order to work correctly in that context.
//
// The code generator that generates the initial file and the one which
// inserts into it must both run as part of a single invocation of protoc.
// Code generators are executed in the order in which they appear on the
// command line.
//
// If |insertion_point| is present, |name| must also be present.
optional string insertion_point = 2;
// The file contents.
optional string content = 15;
