Task Sequence – Split Times

Seen a few examples out there where others have been outputting the start and end times of a Task Sequence to a text file, so wanted to take this one step further and provide you with Split Timings of a running Task Sequence

The script will write to a comma-separated log file of each time it is called and then calculate the split time from the last time it was executed.

Create a Standard Package with a file containing the script ‘Get-TimeStamp.ps1

Get-TimeStamp.ps1 – Script also available at https://github.com/Drakey2000/CommunityHelper/tree/master/Get-TimeStamp

<#
.SYNOPSIS
    Enables you to add Task Sequence Task Steps and it will record the time it was initiated and calculate the duration
    of time passed from when it was last initiated

.DESCRIPTION
    Get-TimeStamp is a function that returns all time stamps and differencec from a running task sequnce

.PARAMETER State
    None


.EXAMPLE
     Get-TimeStamp

.OUTPUTS
    C:\Windows\Logs\ComputaCenter\TaskSequenceName-Timestamp.log

Try{
    # Import Microsoft.SMS.TSEnvironment
    $TSEnv = New-Object -COMObject Microsoft.SMS.TSEnvironment

    # Get Script Name - Without Extention
    $FileName = (Get-Item $PSCommandPath).Basename

    # Set Log File
    $Logfile = "$($env:windir)\CCM\Logs\_$($TSEnv.Value('_SMSTSPackageName'))-$FileName.log"

    # Create Log Folder
    New-Item -Path (Split-Path -Path $Logfile) -ItemType Directory -Force

    # Create Column Headers
    If(!(Test-Path -Path $Logfile)){Add-Content $Logfile -Value "Step Name,Start Timestamp,Duration Split - Days.Hrs.Mins:Secs"}

    # Get Current Time Stamp
    $CurrentTime=(Get-Date)

    # Get Running Step
    $Step = $TSEnv.Value('_SMSTSCurrentActionName')

    # Get Previous Time Stamp to Work Out Duration
    Try{

        # Calculate Time Split
        $Duration = (New-TimeSpan -Start $TSEnv.Value('LastTimeStamp') –End $CurrentTime)

        # Convert Time Split to Days. Hours : Minutes : Seconds
        $DurationString = "{0:dd}.{0:hh}:{0:mm}:{0:ss}" -f $Duration

    }Catch{}

    # Write TimeStamp Log - Comma Seperated
    Add-Content $Logfile -Value "$Step,$CurrentTime,$DurationString"

    # Update LastTimeStamp
    $TSEnv.Value('LastTimeStamp') = $CurrentTime

}Catch{ Add-Content $Logfile -Value $_.Exception.Message; Exit 1}




Then simply add a Run PowerShell script at every point in the Task Sequence you are looking to produce a Time Stamp for


Type : Run PowerShell Script
Name : ‘Step # and description’
Package: ‘Package containing the Get-TimeStamp.ps1’
Script name: Get-TimeStamp.ps1
PowerShell Execution policy : Bypass

After the Task Sequence has completed you will be able to find the corresponding Get-TimeStamp log in the folder C:\Windows\CCM\Logs\_tasksequencename-Get-TimeStamp.log’

As the log file has been written to as comma-separated-values, you can view in a text viewer, or see the information clearly when import into excel, through Data – From Text/CSV

Example

The Duration Split is the time difference from the previous step – Have fun playing !
