WCF Trace & View Trace Logs

12/02/2008

이미 관련글들이 많습니다만 일단 정보를 한곳에 모은다는 생각으로 글을 올립니다.

WCF 응용프로그램을 작성하고 테스트를 진행하다 보면 메시지의 흐름이나 실제 패킨의 생김새를 확인하면서 진행해야 할 경우 생기게 됩니다.

Configuring Tracing

https://msdn2.microsoft.com/en-us/library/ms733025.aspx

이때 아래의 링크를 이용해서 Application 이나 Service의 configuration 파일의 내용을 변경하고 실행하게 되면 .svclog 파일들이 생성됩니다.

Configuration 파일의 대략적인 샘플은 아래와 같습니다. 아래에서 {LogFolder} 를 실제 작업 폴더로 설정하시면 됩니다. 당연히 관련 폴더에 대해서 실행 프로세스의 권한으로 파일을 읽고 쓸 수 있도록 권한도 주셔야 합니다.

만일 실제 이동되는 실제 자료까지 확인이 필요하고 netmon등의 사용이 여의치 않은 경우는 아래 설정을 해주시면 비슷한 효과를 보실 수 있습니다. 물론 정확한 자료는 netmon이나 WhireShark등을 통해서 가능 하겠지요.

처음 설정예와 달리 각 Source들의 로깅 레벨을 한군데에 모아서 변하게 변경하려면 아래와 같이 Switches를 이용하면 됩니다.

물론 위의 설정으로 수집되는 파일들을 저장할 listener 도 등록이 되어야 겠지요.

아래는 위의 설정에서 수집된 자료의 예 입니다.

연결되는 서버와 전달되는 헤더, 데이터가 보여지고 있네요.
