How to set PowerShell eventlog max size in a GPO

Thomas Nielsen 21

Hi there.

I need to set the PowerShell event log in Windows max size in a GPO.

I allready got the Eventlog Max size for: Application, Security, Setup, and System down in the: "Windows Components/Event Log Services" area

My google foo has run out for this one.
Please help me out wise people :-)

Kind regards
Thomas....

Hey,

I've used the following registry key set via GPO Computer Configuration > Preferences > Windows Settings > Registry

HKLM:\Software\Microsoft\Windows\CurrentVersion\WINEVT\Channels\Microsoft-Windows-PowerShell/Operational

and set MaxSize value (in bytes)

GPO does not have out of the box ADMX/ADML file for PowerShell Event logs. If you can build your own ADML/ADMX or find some template, that can solve your problem.

Hi there,

Can you give this a try?

Open the registry editor and go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\<log_name>.
For example: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Directory Service
Set the MaxSize to the required decimal value (in bytes).
