Zipkin |
Zipkin is a OpenTracing plugin.
It's also works with Apache SkyWalking
, which is support Zipkin v1/v2 format.
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 specify your external ip address. |
Here's an example, enable the zipkin plugin on the specified route:
curl http://127.0.0.1:9080/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:
e.g. using docker:
sudo docker run -d -p 9411:9411 openzipkin/zipkin
Here is a test example:
$ 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
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:
$ 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.
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()
})
}
