Zipkin

Zipkin 은 분산 트레이싱 시스템입니다. 마이크로서비스 분산 환경 모니터링을 위해서, Spring Cloud Sleuth와 Zipkin을 연동하여 분산환경에서의 이벤트 로그를 모니터링할 수 있습니다.

Zipkin의 Quickstart에는 Zipkin을 시작하는 3가지 방법이 소개되어 있습니다. 여기서는 Java로 실행하는 것을 다룹니다.

설치

latest release 를 다운로드합니다(ex. zipkin-server-2.12.0-exec.jar).

$ cd /c/infra/                              # 다운로드 정위치는 C:\infra 라고 정  
$ java -jar zipkin-server-2.12.0-exec.jar   # http://localhost:9411

실행 예시

다음은 Zipkin 서버 실행로그입니다.
