ScriptLogger PowerShell Module

PowerShell Module to provide logging capabilities for PowerShell controller scripts.


With the ScriptLogger module, you are able to log error, warning, informational and verbose messages into log files, the Windows event log and the current console host. You can start and stop the logger as required. Works great in cooperation with the ScriptConfig module to improve controller scripts.


The following minimum requirements are necessary to use this module:

  • Windows PowerShell 3.0
  • Windows Server 2008 R2 / Windows 7


With PowerShell 5.0, the new PowerShell Gallery was introduced. Additionally, the new module PowerShellGet was added to the default WMF 5.0 installation. With the cmdlet Install-Module, a published module from the PowerShell Gallery can be downloaded and installed directly within the PowerShell host, optionally with the scope definition:

Install-Module ScriptLogger [-Scope {CurrentUser | AllUsers}]

Alternatively, download the latest release from GitHub and install the module manually on your local system:

  1. Download the latest release from GitHub as a ZIP file: GitHub Releases
  2. Extract the module and install it: Installing a PowerShell Module


  • Start-ScriptLogger
    Start the script logger inside the current PowerShell session.

  • Stop-ScriptLogger
    Stop the script logger inside the current PowerShell session.

  • Set-ScriptLogger
    Update the script logger log configuration.

  • Get-ScriptLogger
    Get the current script logger object.

  • Write-VerboseLog
    Log a verbose message.

  • Write-InformationLog
    Log an information message.

  • Write-WarningLog
    Log a warning message.

  • Write-ErrorLog
    Log an error message.


The following example show two options how to start the script logger, the logger management and how to log the log messages.

# Initialize the logger with default values

# Second options, specify multiple custom settings for the logger
Start-ScriptLogger -Path 'C:\Temp\test.log' -Format '{0:yyyy-MM-dd}   {0:HH:mm:ss}   {1}   {2}   {3,-11}   {4}' -Level Warning -Encoding 'UTF8' -NoEventLog -NoConsoleOutput

# Get the current script logger configuration object

# Update the script logger configuration
Set-ScriptLogger -Level Verbose

# Log an error record
try { 0 / 0 } catch { Write-ErrorLog -ErrorRecord $_ }

# Log an error message
Write-ErrorLog -Message 'My Error Message'

# Log a warning massage
Write-WarningLog -Message 'My Warning Message'

# Log an information message
Write-InformationLog -Message 'My Information Message'

# Log a verbose message
Write-VerboseLog -Message 'My Verbose Message'

# Disable the logger

Please feel free to contribute by opening new issues or providing pull requests. For the best development experience, open this project as a folder in Visual Studio Code and ensure that the PowerShell extension is installed.

This module is tested with the PowerShell testing framework Pester. To run all tests, just start the included test script .\Scripts\test.ps1 or invoke Pester directly with the Invoke-Pester cmdlet. The tests will automatically download the latest meta test from the claudiospizzi/PowerShellModuleBase repository.

To debug the module, just copy the existing .\Scripts\debug.default.ps1 file to .\Scripts\debug.ps1, which is ignored by git. Now add the command to the debug file and start it.
