ULS log files are created but are empty

Problem: I have created a SharePoint 2013 farm with a custom location for my log files e.g. d:\logs.  On the 1st SP2013 VM that created the SP farm using AutoSPInstaller, the logs are present and logging correctly.  On the other/remaining SP VM's, the logs are created every 30 min however, the lof files are empty.

Initial Hypothesis: I had no idea and after looking at google the answer is permissions on the local file system.  Justin Kobel's post gives the fix.

Resolution:

Or run this Powershell on each VM:

PS> $computer= "$env:computername"
PS> $group="Performance Log Users"
PS> $domain="demo"
PS> $user="pbeck"
PS> $de = [ADSI]"WinNT://$computer/$Group,group"
PS> $de.psbase.Invoke("Add",([ADSI]"WinNT://$domain/$user").path)

PS> net stop SPTraceV4
PS> net start SPTraceV4

 

Tip: Using the Invoke-Command you can loop thru and connect to the SP VM's remotely and run the change on each VM in the SP far.  PS to loop thru and change local security groups is here and the xml is here.

You will notice that the files within Windows explorer are shown with a blue colour.  This is to show the files/folders are compressed. 
Blue means compressed.
