SpringCloudでSleuth+ZipKinを使う

ソフトウェアバージョン
SpringBoot
2.1.4.RELEASE
SpringCloud
Greenwich.SR1
zipkin
2.12.2
ZipKinサービスの構築
Pomファイルへの依存関係の導入

    1.8
    2.12.2


    io.zipkin.java
    zipkin-server
    ${zipkin.version}


    io.zipkin.java
    zipkin-autoconfigure-ui
    ${zipkin.version}


    io.zipkin.java
    zipkin-autoconfigure-storage-mysql
    ${zipkin.version}

Javaコード

@SpringBootApplication
@EnableZipkinServer
public class ZipkinServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(ZipkinServerApplication.class, args);
    }
}

サービス構成
アプリケーションでyml zipkin構成を追加し、トレースデータをmysqlに保存することを指定します.

server:
  port: 9441
spring:
  application:
    name: zipkin-server
zipkin:
  storage:
    type: mysql
    mysql:
      jdbcUrl: jdbc:mysql://localhost:3306/zipkin?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=GMT%2B8
      username: root
      password: abcdefg
management:
  metrics:
    web:
      server:
        auto-time-requests: false #       

トレースデータをすべてMySQLに保存するため、データ構築文が必要です.SQLスクリプトはzipkin-storatge-mysql-v 1にあります.2.12.1.jarのmysql.sqlでは、コピーすればいいです.
起動およびアクセス
ZipkinServerApplicationを起動すると、アドレス

http://localhost:9441

を参照してください.
マイクロサービスでSleuthを使用する
マイクロサービスにおける相関依存の導入

    org.springframework.cloud
    spring-cloud-starter-sleuth


    org.springframework.cloud
    spring-cloud-sleuth-zipkin

サービス構成
アプリケーションでxmlでSleuthの関連パラメータを設定する

spring:
  application:
    name: sleuth-demo
  zipkin:
    base-url: http://localhost:9441
  sleuth:
    sampler:
      probability: 1.0 

spring.zipkin:zipkinサービスのアドレスを指定する

spring.sleuth.sampler.probability:サンプリングレートを指定します.デフォルトは0.1で、1.0に変更します.つまり、すべてのサンプリングです.

マイクロサービスの起動
マイクロサービスを開始し、リクエストを開始するとzipKinに追跡データが表示されます.
