spring cloud 與zipkin集成

根據前面介紹的，zipkin主要分爲客戶端和服務集成兩部分。java

服務端web

主要技術點：spring

Collector：rabbitmqsql

測試服務類：

HelloController.java

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {
	@RequestMapping("hello")
	public String hello() {

後記

本章採用zipkin2.9.4與spring boot 2.1.0.BUILD-SNAPSHOT集成。消息通道由默認的http協議更換爲rabbitmq，解決高性能和高併發問題。因爲是測試環境，採用內存存儲。生產環境建議更換爲elasticsearch存儲。

客戶端採集只記錄了服務間調用的性能數據採集，sql、方法間調用的性能數據沒有收集。測試採樣率爲1.0，即爲全量採集，能夠修改spring.sleuth.sampler.probability參數，默認爲0.1。生產環境不建議開啓全量採集。

曾經在生產環境部署apm工具，一個應用集羣一天採集64g日誌數據，這個數據量較大，對服務器帶寬會形成極大衝擊，在生產環境使用須要合理考慮組網問題。
