請問網路流量紀錄。可以記錄到每分鐘
我有測試過NetWorx,WatchLan似乎都只能記錄每日，保留記錄3天內
而我想要記錄到每分鐘，這是因為我們有一個設備類似WebCam，是直接透過網路線傳輸影像到電腦
但常常在半夜設備系統會當機，設備商說有可能是因為網路傳輸訊號的問題(異常)，所以想找可每分鐘紀錄網路流量的軟體，來判斷當機前後幾分鐘是否網路流量瞬間過大，進而影響系統或設備傳輸訊號

謝謝一級屠豬士的指教，我是根據一級屠豬士的提示，用C#方式寫出來的，因為我沒學過Python
，但我這種小程式，實在不敢發表什麼技術文件，所以把程式都貼在下面，(大多程式碼都是網路搜尋後結合的)
功能:每天產生一個年月日.txt的文件檔，然後每5秒計算一次流量，寫入文件檔
