Strange problem



Hi, where is the problem?

My Code:


set-item wsman:\localhost\Client\TrustedHosts -value $hvHost -Force
$password = ConvertTo-SecureString "xxxxx" -AsPlainText -Force
$user = "LAIAUTO\support"
$cred = New-Object System.Management.Automation.PSCredential ($user,$password)
$s = New-PSSession -ComputerName $hvHost -Credential $cred

Invoke-Command -Session $s{

# -----------------------

$CurrentDate = (Get-Date)

$Results = Get-VMReplication | Select VMName, VMId, ReplicationMode, ReplicationHealth, ComputerName,`
                                             PrimaryServer, ReplicaServer, LastReplicationTime, ReplicationState `
                                             | Where-Object ReplicationMode -eq "Primary"

$xmlstring = "<?xml version=`"1.0`"?>`n    <prtg>`n"

ForEach ($eachresult IN $Results) {

$TotalMinutes = (New-Timespan –Start $eachresult.LastReplicationTime –End $CurrentDate).TotalMinutes

$xmlstring += "    <result>`n"
$xmlstring += "        <channel>$($eachresult.VMname)</channel>`n"
$xmlstring += "        <unit>Custom</unit>`n"
$xmlstring += "        <CustomUnit>min</CustomUnit>`n"
$xmlstring += "        <mode>Absolute</mode>`n"
$xmlstring += "        <showChart>1</showChart>`n"
$xmlstring += "        <showTable>1</showTable>`n"
$xmlstring += "        <float>0</float>`n"
$xmlstring += "        <value>$(IF ($TotalMinutes -lt 1) {"0"} ELSE {IF ($TotalMinutes -le 60) {$TotalMinutes.ToString("#")} ELSE {"60"}})</value>`n"
$xmlstring += "        <LimitMaxError>59</LimitMaxError>`n"
$xmlstring += "        <LimitMaxWarning>20</LimitMaxWarning>`n"
$xmlstring += "        <LimitWarningMsg>Hyper-V Replication for this VM is in Warning state</LimitWarningMsg>`n"
$xmlstring += "        <LimitErrorMsg>Hyper-V Replication failed for this VM and is in Critical state</LimitErrorMsg>`n"
$xmlstring += "        <LimitMode>1</LimitMode>`n"
$xmlstring += "    </result>`n"


$xmlstring += "    </prtg>"

Write-Host $xmlstring

If I run this on PS console work fine
PS C:\Program Files (x86)\PRTG Network Monitor\Custom Sensors\EXEXML> .\Replica.ps1 -hvHost
<?xml version="1.0"?>
        <channel>VM2019OR-01 (SALONE)</channel>
        <LimitWarningMsg>Hyper-V Replication for this VM is in Warning state</LimitWarningMsg>
        <LimitErrorMsg>Hyper-V Replication failed for this VM and is in Critical state</LimitErrorMsg>

But my PRTG server send me error

Sensor XML Custom EXE/Script Sensor

XML: The returned XML does not match the expected schema. (code: PE233) -- JSON: The returned JSON does not match the expected structure (No mapping for the Unicode character exists in the target multi-byte code page). (code: PE231)

And log file is:

A command that prompts the user for information failed because the host program or command type does not support user interactions. Try a host program that supports such interactions, such as the Windows PowerShell console or Windows PowerShell ISE, and remove prompt-related commands from command types that don't support user interactions, such as Windows PowerShell workflows.

Whre is the problem????? Ty

Just to make sure, are you using the Exe/Script or Exe/Script Advanced sensor?
The Output your scripts provides is formatted for the Exe/Script Advanced sensor (EXEXML folder in PRTG).

If you are already using the Advanced sensor, you can check under what security context the sensor runs in its Settings tab. We recommend to use the Windows credentials of the parent device, and in the device have the same user configured that you used to run the script manually.

In this case, I would recommend that you open a support ticket. You can do this by sending a email at [email protected].

When you open the ticket it would be good to include screenshots of the Overview, Log and Settings tab of the sensor.
