Using trace route script shows hop count in PRTG monitor

Hello Tenshin,

Thanks for the KB post.

Can you run the script that the sensor uses, manually in PowerShell and check if you get valid results? Also, please send me the result of the output you get from the script.

With kind regards

Dear Siau Hen,

Thanks your reply , I run the script manually in PowerShell param( [string]$target ) $trace=tnc $target -TraceRoute $count=[string]$trace.TraceRoute.Count foreach ($ip in $trace.TraceRoute) { $result=$result+$ip+" > " } $result=$result.Substring(0,$result.Length-3) $message=$count+" hops to reach "+$target+" via "+$result write-host $count":"$message but reports error below Resolve-DnsName : 無法驗證 'Name' 參數上的引數。引數為 Null 或空的。請提供一個不為 Null 或空白的引數，然後嘗試重新執行該命令。 位於 C:\windows\system32\WindowsPowerShell\v1.0\Modules\NetTCPIP\Test-NetConnection.psm1:313 字元:74 + ... ctionResult.DNSOnlyRecords = @( Resolve-DnsName $ComputerName -DnsOnl ... + ~~~~~~~~~~~~~ + CategoryInfo : InvalidData: (:) [Resolve-DnsName]，ParameterBindingValidationException + FullyQualifiedErrorId : ParameterArgumentValidationError,Microsoft.DnsClient.Commands.ResolveDnsName I think this error due to there is no parameter input , so I assign the parameter in the script like below, and marking the variable param with "# "

#param(
#[string]$target
#)
$target="www.google.com.tw"
$trace=tnc $target -TraceRoute
$count=[string]$trace.TraceRoute.Count
foreach ($ip in $trace.TraceRoute) {
$result=$result+$ip+" > "
}
$result=$result.Substring(0,$result.Length-3)
$message=$count+" hops to reach "+$target+" via "+$result
write-host $count":"$message

It is worked , so I think this problem is PRTG can't send parameter back correctly ,

Any suggestion will be appreciated .

If you have e-mail , I can send more detail information to you , by the way , our PRTG major distributor tells me , this question is out off scope of our maintenance , Oh my god! , dumbfounding!

Hi Tenshin,

If you check the settings of the sensor, you may see the Parameter fields there for you to key in.

Paessler indeed doesn't support the script, but we will help our user to solve the issue if it's related to PRTG.

In case you still face an issue, could you please send in your query to [email protected]? Please put PAE2308683 as the email subject.

Thanks!
