[維修小札] 如何持續測試網路PING值並且記錄 How to continuously test network ping values and record them

大概是這樣的功能，他會持續監測，並且記錄PING值。

如果有timeout，會另存檔案作紀錄。

The functionality is like this: 

      it continuously monitors and records ping values. 

The output file name is ping_log.txt. 

If there is a timeout, it saves the record in a separate file, ping_error_log.txt.

先建立一個純文字檔案，並且將下面程式碼貼入裡面。

然後將附檔名改成.ps1

First, create a plain text file and paste the following code into it. 

Then, change the file extension to .ps1.

$OutputFile = "ping_log.txt"

$ErrorFile = "ping_error_log.txt"

$PingTarget = "168.95.1.1"

while ($true) {

    $PingResult = Test-Connection -ComputerName $PingTarget -Count 1 -ErrorAction SilentlyContinue

    $Timestamp = Get-Date -Format "yyyy-MM-dd HH:mm:ss"

    if ($PingResult) {

        $LogEntry = "$Timestamp `t $($PingResult.Address) `t Time=$($PingResult.ResponseTime)ms `t TTL=$($PingResult.Ttl)"

        

        Add-Content -Path $OutputFile -Value $LogEntry

        

        if ($PingResult.ResponseTime -eq $null -or $PingResult.ResponseTime -eq 0) {

            $ErrorLogEntry = "$Timestamp `t $($PingResult.Address) `t Time=ms `t TTL=$($PingResult.Ttl)"

            # Write abnormal entries to the error log file

            Add-Content -Path $ErrorFile -Value $ErrorLogEntry

        }

    } else {

        $LogEntry = "$Timestamp `t $PingTarget `t Request timed out"

        

        Add-Content -Path $OutputFile -Value $LogEntry

        Add-Content -Path $ErrorFile -Value $LogEntry

    }

    Start-Sleep -Seconds 1

}

右鍵"用PowerShell執行"

他就會動產生 ping_log.txt隨時記錄，

並且在timeout的時候會另存ping_error_log.txt 方便觀測。

Right-click and select "Run with PowerShell".

It will generate ping_log.txt to continuously record.

It saves to ping_error_log.txt, when there is a timeout.
