SharePoint Trace Logs Files 0kb

If you plan to use a low privilege account to run "SharePoint Tracing Service" (that is raccomanded), probably this will result in 0kb log files. This is due to lack of permission of this account to the LOG folder.
Instead of add the user directly to the folder you should add this account to a specific Windows Local Group named "Performance Log Users".

Once added the account, restart "SharePoint Tracing Service" in order to Apply changes.

From this point, Trace Log files will be correctly populate.
