- 23. Spring Boot Actuator Metrics URL /actuator/metrics/jvm.memory.used
- 24. Metrics Endpoint
- 25. Metrics Endpoint Metrics – Spring Boot 1 계층적 지표 구조 200 응답 /some-url 요청 수 - counter.status.200.some-url 404 응답 /** 요청 수 - counter.status.404.star-star
- 26. Metrics Endpoint Metrics – Spring Boot 1 “/some-url“ Requests counter.status.200.some-url with region and cloud and exception region.cloud. .exception A Cloud에서 발생한 모든 예외 요청의 수를 보고 싶어요.
- 27. Metrics Endpoint Metrics – Spring Boot 1
- 28. Metrics Endpoint Metrics – Spring Boot 2 Dimensional 지표 구조 Tags == Dimension == key/value pair 장점 - 이해하기 쉬움 - 여러 관점에서 지표 분석 가능 - 유연함. 손쉬운 Tag 추가/삭제

- 30. Metrics Endpoint Metrics with Tags - /actuator/metrics/jvm.memory.used ? tag=area:heap
- 31. Metrics Endpoint Metrics with Tags - /actuator/metrics/jvm.memory.used ? tag=area:heap & tag=id:Par+Eden+Space
- 32. Metrics Endpoint Metrics – Infra Resource system.cpu.usage system.cpu.count system.load.average.1m process.cpu.usage process.file.open process.uptime
- 33. Metrics Endpoint Metrics – JVM jvm.memory.used, committed, max jvm.threads.states jvm.gc.pause jvm.classes.loaded jvm.buffer.capacity
- 34. Metrics Endpoint http.server.requests http.client.requests logback.events tomcat.* jdbc.* Metrics - Application
- 35. Metrics Endpoint http.server.requests http.client.requests logback.events tomcat.* jdbc.* Metrics - Application

- 37. Metrics Endpoint Metric - http.server.requests
- 38. Metrics Endpoint Metric - http.server.requests
- 39. Metrics Endpoint Metric - http.server.requests outcome tag - 1xx -> INFORMATIONAL - 2xx -> SUCCESS - 3xx -> REDIECTION - 4xx -> CLIENT_ERROR - 5xx -> SERVER_ERROR
- 40. Metrics Endpoint Rate and Duration of Success - http.server.requests?tag=outcome:SUCCESS Rate and Duration of Errors - http.server.requests?tag=outcome:SERVER_ERROR - http.server.requests?tag=exception:IllegalArgumentException Metric - http.server.requests

- 67. Conclusion Spring Boot Actuator Endpoint Metrics Micrometer Registry Meter Tag
- 69. Conclusion
- 70. Conclusion
- 71. Conclusion
- 73. Conclusion Dependencies For Monitoring Spring Boot 1.5
- 74. Conclusion Pros Cons - Spring Boot Ecosystem - 손쉬운 설치 - 손쉬운 배포 - 손쉬운 커스터마이징 - 백엔드로부터 독립적 - 코드 수준의 상세한 프로파일링 지표 미제공 - Auto Configuration Spring Boot Only 기존 모니터링 에이전트와의 차이점?
- 75. Conclusion 모든 것을 해결해주지는 않는다. No Silver Bullet! 그러나 짐을 덜어줄 수는 있을 것이다.
