예외

ArgumentOutOfRangeException

지정된 값이 64보다 작거나 4194240보다 크거나 64의 짝수 배수가 아닌 경우

InvalidOperationException

Log 값이 올바른 로그 이름이 아닌 경우

또는

이벤트 로그의 레지스트리 키를 대상 컴퓨터에서 열 수 없는 경우

예제

다음 예제에서는 로컬 컴퓨터에 정의된 이벤트 로그를 열거하고 각 이벤트 로그에 대한 구성 세부 정보를 표시합니다.

설명

속성은 MaximumKilobytes 이벤트 로그 파일의 크기 제한을 나타냅니다. 이벤트 로그가 크기 제한에 도달하면 구성된 OverflowAction 값은 새 항목이 삭제되는지 또는 새 항목이 이전 항목을 덮어쓸지 여부를 결정합니다.

참고

이 속성은 이 instance 나타내는 이벤트 로그에 대한 구성 설정을 나타냅니다. 이벤트 로그가 최대 크기에 도달하면 이 속성은 운영 체제가 이벤트 로그에 등록된 모든 이벤트 원본에서 작성한 새 항목을 처리하는 방법을 지정합니다.
