Possible Write-log bug

Francois · November 13, 2015, 3:49pm

Hi,

I am running a function returning an array of values then I convert it to string and using write-log to pipe it in my log in CMTrace format. But instead, I see the value in the log with Notepad but not with CMTrace. And, worst, after that if I run the script again the log is no more recognise as CMTrace.

<code>
Function Get-MonitorInfo
{
    [CmdletBinding()]
    Param
    (
        [Parameter(
        Position=0,
        ValueFromPipeLine=$true,
        ValueFromPipeLineByPropertyName=$true)]
        [string]$name = &#039;.&#039;
    )
    Begin { 

		## Get the name of this function and write header
		#[string]${CmdletName} = $PSCmdlet.MyInvocation.MyCommand.Name
		Set-StrictMode -off
			#Write-FunctionHeaderOrFooter -CmdletName ${CmdletName} -CmdletBoundParameters $PSBoundParameters -Header
		Set-StrictMode -Version Latest

	 }## End Begin Script Block 
 
    Process
    {
 
        $ActiveMonitors = Get-WmiObject -Namespace root\wmi -Class wmiMonitorID -ComputerName $name
        $monitorInfo = @()
 
        foreach ($monitor in $ActiveMonitors)
        {
            $mon = New-Object PSObject
            $manufacturer = $null
            $product = $null
            $serial = $null
            $name = $null
            $week = $null
            $year = $null

            $monitor.SerialNumberID | foreach {$serial += [char]$_}

    End {

	}## End End 
}
</code>

<code>

Thanks,

I think the problem is that you’re not using the Write-Log function as it’s designed to be used. Model your Write-Log call like the other calls in the toolkit.

Write-Log -Message $StrMonitorDataTexte -Source ${CmdletName}

Hi,

Seems not.

Possibly the array cannot be directly pipe (even with | out-string) to the log. Any idea?

Francois · November 13, 2015, 4:48pm

Seems Write-log does love the empty line between monitors.

Manufacturer : DEL
ProductCode : A07E
SerialNumber : xxx
Name : DELL P2212H
Week : 47
Year : 2013

Manufacturer : DEL
ProductCode : A098
SerialNumber : xxx
Name : DELL P2214H
Week : 28
Year : 2015

If I remove it manually or put === then everything is fine. Any idea how making write-log accepting it or replacing the empty line with === ?

mmashwani · November 13, 2015, 6:15pm

Are you sure you’re using the new version of CMTrace that came with SCCM 2012? The older version of the utility does not work with the new CMTrace log format.

mmashwani · November 13, 2015, 6:25pm

Well I guess you do have the latest version of CMTrace if it works when you get rid of the empty line. There must be some character code of some sort that messes up the log file when you turn that array into a string using Out-String.

Do this instead to join the array into a string:
[string]$StrMonitorData=$monitorInfo | Format-List | Out-String

Francois · November 13, 2015, 7:45pm

I am running CMTrace 5.0.7804-1000 (32-bit). No the problem is still there.

<code>
[string]$StrMonitorData=$monitorInfo | Format-List | Out-String
Write-Log -Message &amp;quot;Ecran: </code>

n$($StrMonitorData)" -Source ${CmdletName}

`

In CMTrace it did not show up.
With Notepad, I get:

]LOG]!><time="14:39:30.046-300" date="11-13-2015" component="Get-PendingReboot" context="xxx\xxx" type="1" thread="3000" file="Info_Depannage1.0_Frv1.ps1"> <![LOG[[Installation] :: Période d'allumage: 0 jours 6 heures 16 minutes]LOG]!><time="14:39:30.093-300" date="11-13-2015" component="" context="xxx\xxx" type="1" thread="3000" file=""> <![LOG[[Installation] :: Ecran:

If manually I am removing a line at the end of that list or between both monitor then I will be correct in CMTrace.

Hi,

I just made a test script with lesser script line and the problem is still appearing.
Easy to reproduce:
