네트워크 문제로 간헐적인 원격지의 DB 연결 실패가 의심될 때, 클라이언트에서 PsPing 툴을 이용하여 TCP Ping 테스트 결과를 로그로 남길 수 있습니다. TCP 특정 포트 연결 성공 여부와 지연을 체크해 볼 수 있겠습니다.

우선 탐색기에서 Psping.exe 를 실행하여 Sysinternals Software License Terms 을 체크합니다.

이후 아래 파워쉘 명령을 통해 1초 단위의 PsPing 결과를 PsPing_log.txt 에 기록합니다. 간격, 대상 IP, 포트, 파일명을 명시해 주시면 됩니다.

PS F:\PSTools> .\psping -t -i 1 192.168.1.10:1433 | foreach{"{0} - {1}" -f (Get-Date),$_} | Tee-object -FilePath PsPing_log.txt


기록된 로그를 살펴 봅니다.
