由于上證所，深交所level1，level2金融數據服務器在上午9：00開始到11：30和下午13：00開始到15：30一共大約5個小時的時間內流量比較大所以被監控服務器的網絡流速算是一個被監控的重要指標。可以通過累加一段時間內各個網卡的上行，下行流量除以這個時間間隔計算出這段時間內的平均網速，我現在的采集頻率是1分鐘采集一次，在實際開盤期間運行過程中得到的網速監控信息用還是比較準確的，都保持在5M/S左右的速度，有時候在平時非服務期看見某臺服務器的內網網卡網速達到5M/S ，果然就是有人在大手筆傳輸。
獨立的監控腳本是返回一個列表嵌套元組的數據結構，最后再匯總成一個完整的XML數據島，為了調試方便腳本的每一個中間結果都導出到一個臨時文本中。
運行以下腳本要確定你的linux裝了ethtool工具，在ubuntu2.6.27-7-server，ubuntu22.6.27.19-5-default，suse 2.6.27.19-5-default 測試通過。

使用例子：
每一個列表元素元組里面第二個元素第一個字段為網速 Bytes/S，例如eth1網卡的網速就是3.3KB/s，eth0網速是2.9KB/s，今天是周六這個流量很正常
