# 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)
|
|
iSpan.End()
|
|
}
|
|
}
|
|
```
