-------------------------------------------------------------------------------------------------- This is a standard module with a set of standard functions used across multiple scripts within CT. Any changes to this module need to be published using the powershell script "Build_CT_Module.ps1" -------------------------------------------------------------------------------------------------- HOW TO IMPORT INTO SCRIPT: -------------------------------------------------------------------------------------------------- This module should be imported using the commands below (do not copy the asterix's, just whats between). This will import this module AND initialise the script with all the standard features required by scripts, including all the log files for each transaction ***************** [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12 Install-Module -Name CT-PS-Standard -Force -AllowClobber Initialize-Script ***************** -------------------------------------------------------------------------------------------------- -------------------------------------------------------------------------------------------------- LOG FILES -------------------------------------------------------------------------------------------------- There are four log files initialised by this module that can be used for output. You can write to each of these logs accordingly. $Output_Log: This is the standard console output. $Transcript_log: This is where the transcript is written to. You will need to start and stop the transcript inside your script by using the command "Start-Transcript -Path $Transcript_log -append | Out-Null" $API_log: This is where the output from API posts should be sent. $Install_log: This is where output from MSIEXEC commands should be logged -------------------------------------------------------------------------------------------------- #> function Initialize-Script { [CmdletBinding(SupportsShouldProcess)] param() <# ---- STANDARD SCRIPT BLOCK ---- This block is standard script settings used across all scripts and enables some consistency. It sets up some standard variables and starts transcript so any errors are caught and can be viewed. If installations are taking place via MSIEXEC, it also establishes the log file. If you are installing more than one installation, make sure you setup multiple Install_Log variables for each installation and name the end of the log file accordingly It starts transcript to the transcript log file so the history can be accessed anytime in the future The script then tests for the CT_DEST folder and creates it if its not there. #> Begin{ # Display some troubleshoot info [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12 Write-Verbose "MyInvocation info: MyCommand: $($MyInvocation.MyCommand) ScriptName: $($MyInvocation.ScriptName) PSScriptRoot: $($MyInvocation.PSScriptRoot) PSCommandPath: $($MyInvocation.PSCommandPath) InvocationName: $($MyInvocation.InvocationName) ScriptLineNumber: $($MyInvocation.ScriptLineNumber) " $P_MyInvocation = $PSCmdlet.SessionState.PSVariable.Get('MyInvocation').Value Write-Verbose "Parent MyInvocation info: MyCommand: $($P_MyInvocation.MyCommand) ScriptName: $($P_MyInvocation.ScriptName) PSScriptRoot: $($P_MyInvocation.PSScriptRoot) PSCommandPath: $($P_MyInvocation.PSCommandPath) InvocationName: $($P_MyInvocation.InvocationName) ScriptLineNumber: $($P_MyInvocation.ScriptLineNumber) " $global:ErrorActionPreference = "Stop" if ($MyInvocation.ScriptName.Length -gt 4) { try { $Global:Script_Name = ($MyInvocation.ScriptName).Replace("$($MyInvocation.PSScriptRoot)\","") $Global:Script_Name = ($Global:Script_Name).Substring(0,($Global:Script_Name).Length-4) } catch { $Global:Script_Name = "Terminal" } } else { $Global:Script_Name = "Terminal" } $global:CT_DEST="C:\CT" # Where the files are downloaded to $global:DateStamp = get-date -Format yyyyMMddTHHmmss # A formatted date strong $global:Output_log = "$CT_DEST\logs\$($Script_Name)\$($DateStamp)_output.log" # The output $global:Transcript_log = "$CT_DEST\logs\$($Script_Name)\$($DateStamp)_transcript.log" # The powershell transcript file $global:API_log = "$($CT_DEST)\logs\$($Script_Name)\$($DateStamp)_API.log" $global:Install_log = "$CT_DEST\logs\$($Script_Name)\$($DateStamp)_install.log" # The powershell installation file } Process { <# This next block is better placed in the script itself, not in this module write-output "********************** Script $($Script_Name) starting. **********************" Write-OutputLog "Output log : $($Output_log)" -verbose:$VerbosePreference Write-OutputLog "Transcript log : $($Transcript_log)" -verbose:$VerbosePreference Write-OutputLog "API log : $($API_log)" -verbose:$VerbosePreference Write-OutputLog "Install log (if used) : $($Install_log)" -verbose:$VerbosePreference Write-Output "Log files can be found at $($CT_DEST)\logs\$($Script_Name)\" #> # Check for a CT folder on the C: and if not, create it, however that location should already exist as part of the Start-Transcript command. if(-not( Test-Path -Path $CT_DEST )) { try{ mkdir $CT_DEST > $null #Transcript-Log "New folder created at $CT_DEST." }catch{ #Can't create the folder, therefore cannot continue Write-Error "Cannot create folder $CT_DEST. $($Error[0].Exception.Message)" Write-Error $_ -verbose:$VerbosePreference #Stop-Transcript exit 1 } } if(-not( Test-Path -Path "$($CT_DEST)\logs" )) { try{ mkdir "$($CT_DEST)\logs" > $null #Transcript-Log "New logs folder created at $CT_DEST." }catch{ #Can't create the folder, therefore cannot continue Write-Error "Cannot create logs folder in $CT_DEST. $($Error[0].Exception.Message)" Write-Error $_ -verbose:$VerbosePreference #Stop-Transcript exit 3 } } if(-not( Test-Path -Path "$($CT_DEST)\logs\$($Script_Name)" )) { try{ mkdir "$($CT_DEST)\logs\$($Script_Name)" > $null #Transcript-Log "New logs folder for $($Script_Name) created at $CT_DEST." }catch{ #Can't create the folder, therefore cannot continue Write-Error "Cannot create logs folder for $($Script_Name) in $CT_DEST. $($Error[0].Exception.Message)" Write-Error $_ #Stop-Transcript exit 4 } } $global:CT_Reg_Path = "HKLM:\Software\CT\Monitoring" $global:CT_Reg_Key = "$($CT_Reg_Path)\$($Script_Name)" if(-not( Test-Path -Path $CT_Reg_Key )) { try{ $CTMonitoringReg = New-Item -Path $CT_Reg_Path -Name $Script_Name -Force Set-ItemProperty -Path "HKLM:\Software\CT" -Name "CustomerNo" -Value $customer }catch{ #Can't create the regkey, therefore cannot continue Write-Error "Cannot create registry key at $($CT_Reg_Key). $($Error[0].Exception.Message)" Write-Error "$($CTMonitoringReg)" Write-Error $_ #Stop-Transcript exit 5 } } # Create Transcript header Write-OutputLog "**********************" Write-OutputLog "Script: $($PSCmdlet.MyInvocation.ScriptName)."
