|
|
|
## Attributes
|
|
|

| Name | Type | Requirement | Default | Valid | Description |
|
|
| ------------ | ------ | ----------- | -------- | ------------ | ------------------------------------------------------------------------------- |
|
|
| endpoint | string | required | | | the http endpoint of Ziplin, for example: `http://127.0.0.1:9411/api/v2/spans`. |
|
|
| sample_ratio | number | required | | [0.00001, 1] | the ratio of sample |
|
|
| service_name | string | optional | "APISIX" | | service name for zipkin reporter |
|
|
| server_addr | string | optional | | | IPv4 address for zipkin reporter, default is nginx built-in variables $server_addr, here you can speific your external ip address. |
|
|
|
|
## How To Enable
|
|
|
|
Here's an example, enable the zipkin plugin on the specified route:
|
|
|
|
```shell
|
|
curl http://127.0.0.1:9180/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
|
{
|
|
"methods": ["GET"],
|
|
"uri": "/index.html",
|
|
"plugins": {
|
|
"zipkin": {
|
|
"endpoint": "http://127.0.0.1:9411/api/v2/spans",
|
|
"sample_ratio": 1,
|
|
"service_name": "APISIX-IN-SG",
|
|
"server_addr": "192.168.3.50"
|
|
}
|
|
},
|
|
"upstream": {
|
|
"type": "roundrobin",
|
|
"nodes": {
|
|
"39.97.63.215:80": 1
|
|
}
|
|
}
|
|
}'
|
|
```
|
|
|
|
You can open dashboard with a browser: `http://127.0.0.1:9080/apisix/dashboard/`, to complete the above operation through the web interface, first add a route:
|
|
|
|

|
|
|
|
Then add zipkin plugin:
|
|
|
|
![](../images/plugin/zipkin-2.png)
|
|
|
|
## Test Plugin
|
|
|
|
### run the Zipkin instance
|
|
|
|
e.g. using docker:
|
|
|
|
```
|
|
sudo docker run -d -p 9411:9411 openzipkin/zipkin
|
|
```
|
|
|
|
Here is a test example:
|
|
|
|
```shell
|
|
$ curl http://127.0.0.1:9080/index.html
|
|
HTTP/1.1 200 OK
|
|
...
|
|
```
|
|
|
|
Then you can use a browser to access the webUI of Zipkin:
|
|
|
|
```
|
|
http://127.0.0.1:9411/zipkin
|
|
```

|
## Disable Plugin
|
|
|
|
When you want to disable the zipkin plugin, it is very simple,
|
|
you can delete the corresponding json configuration in the plugin configuration,
|
|
no need to restart the service, it will take effect immediately:
|
|
|
|
```shell
|
|
$ curl http://127.0.0.1:2379/v2/keys/apisix/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d value='
|
|
{
|
|
"methods": ["GET"],
|
|
"uri": "/index.html",
|
|
"plugins": {
|
|
},
|
|
"upstream": {
|
|
"type": "roundrobin",
|
|
"nodes": {
|
|
"39.97.63.215:80": 1
|
|
}
|
|
}
|
|
}'
|
|
```
|
|
|
|
The zipkin plugin has been disabled now. It works for other plugins.

## example code for upstream ( golang with Gin )
|
|
|
|
```golang
|
|
func GetTracer(serviceName string, port int, enpoitUrl string, rate float64) *zipkin.Tracer {
|
|
// create a reporter to be used by the tracer
|
|
reporter := httpreporter.NewReporter(enpoitUrl)
|
|
// set-up the local endpoint for our service host is ip:host
|
|
|
|
thisip, _ := GetLocalIP()
|
|
|
|
host := fmt.Sprintf("%s:%d", thisip, port)
|
|
endpoint, _ := zipkin.NewEndpoint(serviceName, host)
|
|
// set-up our sampling strategy
|
|
sampler, _ := zipkin.NewCountingSampler(rate)
|
|
// initialize the tracer
|
|
tracer, _ := zipkin.NewTracer(
|
|
reporter,
|
|
zipkin.WithLocalEndpoint(endpoint),
|
|
zipkin.WithSampler(sampler),
|
|
)
|
|
return tracer
|
|
}
|
|
|
|
func main(){
|
|
r := gin.Default()
|
|
|
|
tracer := GetTracer(...)
|
|
|
|
// use middleware to extract parentID from http header that injected by APISIX
|
|
r.Use(func(c *gin.Context) {
|
|
span := this.Tracer.Extract(b3.ExtractHTTP(c.Request))
|
|
childSpan := this.Tracer.StartSpan(spanName, zipkin.Parent(span))
|
|
defer childSpan.Finish()
|
|
c.Next()
|
|
})
|
|
|
|
}
|
|
```
