通过 VBScript 从主机名列表对 Excel 进行持续 ping 更新

Question

以下 VBScript 将显示主机名列表中单个 ping 命令的状态到 Excel 电子表格：

Set objExcel = CreateObject("Excel.Application")
 
objExcel.Visible = True
 
objExcel.Workbooks.Add
 
intRow = 2
 
'# Define Labels 
objExcel.Cells(1, 1).Value = "Node"
 
objExcel.Cells(1, 2).Value = "Status"

'# Create file system object for reading the hosts from text file

Set Fso = CreateObject("Scripting.FileSystemObject")
 
Set InputFile = fso.OpenTextFile("MachineList.Txt")
 
'# Loop thru the text file till the end 
 
Do While Not (InputFile.atEndOfStream)
 
HostName = InputFile.ReadLine
  
'# Create shell object for Pinging the host machines
Set WshShell = WScript.CreateObject("WScript.Shell")
 
Ping = WshShell.Run("ping -n 1 " & HostName, 0, True)
 
 
objExcel.Cells(intRow, 1).Value = HostName
 
'# use switch case for checking the machine updown status
 
Select Case Ping
Case 0
    objExcel.Cells(intRow, 2).Value = "Up"
    objExcel.Cells(intRow, 2).Interior.Color = vbGreen
Case 1
    objExcel.Cells(intRow, 2).Value = "Down"
    objExcel.Cells(intRow, 2).Interior.Color = vbRed
End Select
 
intRow = intRow + 1
 
Loop
 
'# Format the excel
 
objExcel.Range("A1:B1").Select
 
objExcel.Selection.Interior.ColorIndex = 19
 
objExcel.Selection.Font.ColorIndex = 11
 
objExcel.Selection.Font.Bold = True
 
objExcel.Cells.EntireColumn.AutoFit

此代码按预期工作。

我想不断 ping 主机名并实时更新到 Excel。我尝试将-t添加到 ping 命令中 - 而不是像在命令提示符下那样-n 1，但脚本被挂起，因为它将在列表中的第一个主机名上停止，并且不会进一步进展。

我的问题：如何实现连续 ping 命令或重复运行脚本？

在网上搜索了几天的解决方案后，我找不到。

使用wscript.sleep并将结果写入文本文件

Dim txt, fso, InputFile, OutputFile, arr, h, Ping, sep
Set fso = CreateObject("Scripting.FileSystemObject")
Set WshShell = wscript.CreateObject("WScript.Shell")
'# load the hosts from a text file into an array
Set InputFile = fso.OpenTextFile("MachineList.Txt")
arr = Split(InputFile.readall(), vbCrLf)
InputFile.Close
Do
    txt = Now & vbcrlf 'add a timestamp
    sep = ""
    For Each h In arr
        Ping = WshShell.Run("ping -n 1 " & h, 0, True)
        txt = txt & sep & h & ","
        If Ping = 1 Then
            txt = txt & "Up"
        ElseIf Ping = 0 Then
            txt = txt & "Down"
        Else
            txt = txt & "???"
        End If
        sep = vbCrLf
    Next 
    Set OutputFile = fso.createTextFile("Results.Txt")
    OutputFile.write txt
    OutputFile.Close
    wscript.sleep 1000 * 60 '60 sec
Loop
