Scripted Multi Sensor Addition

Hi

I have the following script (I know the output format isn't correct) that I would like to use to monitor a Hyper-v Cluster.

Script Start
==========
function Get-ClusterVM {

[CmdletBinding()]
param(
[Parameter(Position=0,Mandatory=$true,HelpMessage="Name of the Cluster to fetch inventory from",
ValueFromPipeline=$true,ValueFromPipelineByPropertyName=$true)]
[System.String]
$ClusterName
)

process {

$Cluster = Get-Cluster -Name $ClusterName
$HVHosts = $Cluster | Get-ClusterNode

foreach ($HVHost in $HVHosts) {
    Get-VM -Computer $HVHost | where {$_.ResourceMeteringEnabled -like "False"} | Enable-VMResourceMetering 
	$VMs = Get-VM -Computer $HVHost | Measure-VM
	foreach ($VM in $VMs) {
		write-host "*********"
		write-host "VMName: "$VM.VMName
        write-host "AvgCPU(Mhz): "$VM.AvgCPU
        write-host "AvgRAM(M): "$VM.AvgRAM
        write-host "AggregatedAverageNormalizedIOPS: "$VM.AggregatedAverageNormalizedIOPS
        write-host "AggregatedAverageLatency: "$VM.AggregatedAverageLatency
        write-host "AggregatedDiskDataRead: "$VM.AggregatedDiskDataRead
        write-host "AggregatedDiskDataWritten: "$VM.AggregatedDiskDataWritten
        write-host "MeteringDuration: "$VM.MeteringDuration
        $InboundTraffic = ($VM.NetworkMeteredTrafficReport | where {($_.Direction -eq "Inbound")} | measure-object TotalTraffic -sum).sum
        $OutboundTraffic = ($VM.NetworkMeteredTrafficReport | where {($_.Direction -eq "Outbound")} | measure-object TotalTraffic -sum).sum
        write-host "InboundTraffic(M): "$InboundTraffic
        write-host "OutboundTraffic(M): "$OutboundTraffic

        $TotalIO = ($VM.AggregatedDiskDataRead + $VM.AggregatedDiskDataWritten)
        if ($TotalIO -eq "0") {
           $ReadPercent = "0"
           $WritePercent = "0"
        }
        else {
        $ReadPercent = ($VM.AggregatedDiskDataRead/$TotalIO)*100
        $ReadPercent = [math]::round($ReadPercent)
        $WritePercent = ($VM.AggregatedDiskDataWritten/$TotalIO)*100
        $WritePercent = [math]::round($WritePercent)
        }

        write-host "Total IO: "$TotalIO
        write-host "% Read Data: "$ReadPercent
        write-host "% Write Data: "$WritePercent
		write-host "*********"    

        #Cleanup Values
        $InboundTraffic = ""
        $OutboundTraffic = ""
        $TotalIO = ""
        $ReadPercent = ""
        $WritePercent = ""
		} 
     Get-VM -Computer $HVHost | Reset-VMResourceMetering
     Get-VM -Computer $HVHost | Enable-VMResourceMetering
	}
} 
}

Get-ClusterVM -clustername $ClusterName

Exit 0
=========

Does anyone know how to take each returned set of data (per VM in this instance) and create a sensor with multiple channels for that sensor? This Sensor would be update on subsequent runs

Any help is appreciated

Thanks

Add something like this to the loop and take it from there:

	$result+="   <result>`r`n"
	$result+="       <channel>AvgCPU(Mhz) " + $VM.VMName + "</channel>`r`n"
	$result+="       <unit>#</unit>`r`n"
	$result+="       <value>"+$VM.AvgCPU+"</value>`r`n"
	$result+="   </result>`r`n"
}		
$result+="   <text>OK</text>`r`n"
$result+="</prtg>`r`n"
$result

Hi

Thanks, but wont the above create multiple channels in a single sensor ?

Thanks

Hello rhyse,
thank you for your reply.

Yes, that's correct. Doing a "loop" for every instance will create a multi-channel sensor which isn't always desirable.

We've recently introduced (In PRTG 16.1.22) a way to do a so-called "metascan" for Exe-sensors, this way the sensor can do a "metascan" (where it will query the list of available instances) and deploy one sensor per instance, please review the official KB-post on the subject:

Best Regards,
